directlx 520b8d08c3 Fix YAML syntax errors in remediation playbooks
Remove document separators (---) between plays in multi-play playbooks.
Ansible expects multiple plays to be in a single YAML document, not
separated by document delimiters.

Fixed files:
- remediate-storage-critical-issues.yml
- remediate-docker-storage.yml
- remediate-stopped-containers.yml
- configure-storage-monitoring.yml

All playbooks now pass ansible-playbook --syntax-check validation.

# CLAUDE.md - dlx-ansible
Infrastructure as Code for DirectLX - Ansible playbooks, roles, and inventory for managing a Proxmox-based homelab infrastructure with multiple services.
## Project Overview
This repository manages 16 servers across Proxmox hypervisors, databases, web services, infrastructure services, and applications using Ansible automation.
## Infrastructure
### Server Inventory
**Proxmox Cluster**:
- proxmox-00 (192.168.200.10) - Primary hypervisor
- proxmox-01 (192.168.200.11) - Secondary hypervisor
- proxmox-02 (192.168.200.12) - Tertiary hypervisor
**Database Servers**:
- postgres (192.168.200.103) - PostgreSQL database
- mysql (192.168.200.110) - MySQL/MariaDB database
- mongo (192.168.200.111) - MongoDB database
**Web/Proxy Servers**:
- nginx (192.168.200.65) - Web server
- npm (192.168.200.71) - Nginx Proxy Manager for SSL termination
**Infrastructure Services**:
- docker (192.168.200.200) - Docker host for various containerized services
- pihole (192.168.200.100) - DNS server and ad-blocking
- gitea (192.168.200.102) - Self-hosted Git service
- jenkins (192.168.200.91) - CI/CD server + SonarQube
**Application Servers**:
- hiveops (192.168.200.112) - HiveOps incident management (Spring Boot)
- smartjournal (192.168.200.114) - Journal tracking application
- odoo (192.168.200.61) - ERP system
**Control**:
- ansible-node (192.168.200.106) - Ansible control node
### Common Access Patterns
- **User**: dlxadmin (passwordless sudo on all servers)
- **SSH**: Key-based authentication (password disabled on most servers)
- **Exception**: Jenkins server has password auth enabled for AWS Jenkins Master connection
- **Firewall**: UFW managed via common role
## Quick Start Commands
### Basic Ansible Operations
```bash
# Check connectivity to all servers
ansible all -m ping
# Check connectivity to specific group
ansible webservers -m ping
# Run ad-hoc command
ansible all -m shell -a "uptime" -b
# Gather facts about servers
ansible all -m setup
```
### Playbook Execution
```bash
# Run main site playbook
ansible-playbook playbooks/site.yml
# Limit to specific servers
ansible-playbook playbooks/site.yml -l jenkins,npm
# Limit to server group
ansible-playbook playbooks/site.yml -l webservers
# Use tags
ansible-playbook playbooks/site.yml --tags firewall
# Dry run (check mode)
ansible-playbook playbooks/site.yml --check
# Verbose output
ansible-playbook playbooks/site.yml -v
ansible-playbook playbooks/site.yml -vvv # very verbose
```
### Security Operations
```bash
# Run comprehensive security audit
ansible-playbook playbooks/security-audit-v2.yml
# View audit results
cat /tmp/security-audit-*/report.txt
cat docs/SECURITY-AUDIT-SUMMARY.md
# Apply security updates
ansible all -m apt -a "update_cache=yes upgrade=dist" -b
# Check firewall status
ansible all -m shell -a "ufw status verbose" -b
# Configure Docker server firewall (when ready)
ansible-playbook playbooks/secure-docker-server-firewall.yml
```
### Server Management
```bash
# Reboot servers
ansible all -m reboot -b
# Check disk space
ansible all -m shell -a "df -h" -b
# Check memory usage
ansible all -m shell -a "free -h" -b
# Check running services
ansible all -m shell -a "systemctl status" -b
# Update packages
ansible all -m apt -a "update_cache=yes" -b
```

## Key Configuration Patterns
### Firewall Management
Firewall is managed by the common role. Configuration is per-host in `host_vars/`:
```yaml
# Example: host_vars/jenkins.yml
common_firewall_enabled: true
common_firewall_allowed_ports:
- "22/tcp" # SSH
- "8080/tcp" # Jenkins
- "9000/tcp" # SonarQube
```
**Firewall Disabled Hosts**:
- docker, hiveops, smartjournal, odoo (disabled for Docker networking)
### SSH Configuration
Most servers use key-only authentication:
```yaml
PasswordAuthentication no
PubkeyAuthentication yes
PermitRootLogin no # (except Proxmox nodes)
```
**Exception**: Jenkins has password authentication enabled for AWS Jenkins Master.
### Spring Boot SSL Offloading
For Spring Boot applications behind Nginx Proxy Manager:
```yaml
environment:
SERVER_FORWARD_HEADERS_STRATEGY: native
SERVER_USE_FORWARD_HEADERS: true
```
This prevents redirect loops when NPM terminates SSL.
### Docker Compose
When .env is not in same directory as compose file:
```bash
docker compose -f docker/docker-compose.yml --env-file .env up -d
```
**Container updates**: Always recreate (not restart) when changing environment variables.
## Critical Knowledge
See `~/.claude/projects/-source-dlx-src-dlx-ansible/memory/MEMORY.md` for detailed infrastructure knowledge including:
- SSL offloading configuration
- Jenkins connectivity troubleshooting
- Storage remediation procedures
- Security audit findings
- Common fixes and solutions
## Common Tasks
### Add New Server
1. Add to `inventory/hosts.yml`:
```yaml
newserver:
ansible_host: 192.168.200.xxx
```
2. Create `host_vars/newserver.yml` (if custom config needed)
3. Run setup:
```bash
ansible-playbook playbooks/site.yml -l newserver
```
### Update Firewall Rules
1. Edit `host_vars/<server>.yml`:
```yaml
common_firewall_allowed_ports:
- "22/tcp"
- "80/tcp"
- "443/tcp"
```
2. Apply changes:
```bash
ansible-playbook playbooks/site.yml -l <server> --tags firewall
```
### Enable Automatic Security Updates
```bash
ansible all -m apt -a "name=unattended-upgrades state=present" -b
ansible all -m copy -a "dest=/etc/apt/apt.conf.d/20auto-upgrades content='APT::Periodic::Update-Package-Lists \"1\";\nAPT::Periodic::Unattended-Upgrade \"1\";' mode=0644" -b
```
### Run Monthly Security Audit
```bash
ansible-playbook playbooks/security-audit-v2.yml
cat docs/SECURITY-AUDIT-SUMMARY.md
```
## Git Workflow
- **Main Branch**: Production-ready configurations
- **Commit Messages**: Descriptive, include what was changed and why
- **Co-Authored-By**: Include for Claude-assisted work
- **Testing**: Always test with `--check` before applying changes
Example commit:
```bash
git add playbooks/new-playbook.yml
git commit -m "Add playbook for X configuration
This playbook automates Y to solve Z problem.
Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>"
```
## Troubleshooting
### SSH Connection Issues
```bash
# Test SSH connectivity
ansible <server> -m ping
# Check SSH with verbose output
ssh -vvv dlxadmin@<server-ip>
# Test from control machine
ansible <server> -m shell -a "whoami" -b
```
### Firewall Issues
```bash
# Check firewall status
ansible <server> -m shell -a "ufw status verbose" -b
# Temporarily disable (for debugging)
ansible <server> -m ufw -a "state=disabled" -b
# Re-enable
ansible <server> -m ufw -a "state=enabled" -b
```
### Playbook Failures
```bash
# Run with verbose output
ansible-playbook playbooks/site.yml -vvv
# Check syntax
ansible-playbook playbooks/site.yml --syntax-check
# List tasks
ansible-playbook playbooks/site.yml --list-tasks
# Start at specific task
ansible-playbook playbooks/site.yml --start-at-task="task name"
```
## Security Best Practices
1. **Always test with --check first**
2. **Limit scope with -l when testing**
3. **Keep firewall rules minimal**
4. **Use key-based SSH authentication**
5. **Enable automatic security updates**
6. **Run monthly security audits**
7. **Document changes in memory**
8. **Never commit secrets** (use Ansible Vault when needed)
## Important Notes
- Jenkins password auth is intentional (for AWS Jenkins Master access)
- Firewall disabled on hiveops/smartjournal/odoo for Docker networking
- Proxmox nodes may require root login for management
- NPM server (192.168.200.71) handles SSL termination for web services
- Pi-hole (192.168.200.100) provides DNS for internal services
## Resources
- **Documentation**: `docs/` directory
- **Security Audit**: `docs/SECURITY-AUDIT-SUMMARY.md`

- **Version Controlled Config**: http://192.168.200.102/directlx/dlx-claude
## Maintenance Schedule
- **Daily**: Monitor server health, check failed logins
- **Weekly**: Review and apply security updates
- **Monthly**: Run security audit, review firewall rules
- **Quarterly**: Review and update documentation

# Docker Server Security - Saved Configuration
**Date**: 2026-02-09
**Server**: docker (192.168.200.200)
**Status**: Security updates applied ✅, Firewall configuration ready for execution
## What Was Completed
### ✅ Security Updates Applied (2026-02-09)
- **Packages upgraded**: 107
- **Critical updates**: All applied
- **Status**: System up to date
```bash
# Packages updated include:
- openssh-client, openssh-server (security)
- systemd, systemd-sysv (security)
- libssl3, openssl (critical security)
- python3, perl (security)
- linux-libc-dev (security)
- And 97 more packages
```
## Pending: Firewall Configuration
### Current State
- **Firewall**: ❌ Not configured (currently INACTIVE)
- **Risk**: All Docker services exposed to network
- **Open Ports**:
- 22 (SSH)
- 5000, 8000, 8001, 8080, 8081, 8082, 8443, 9000, 11434 (Docker services)
### Recommended Configuration Options
#### Option A: Internal Only (Most Secure - Recommended)
**Use Case**: Docker services only accessed from internal network
```bash
ansible-playbook playbooks/secure-docker-server-firewall.yml -e "firewall_mode=internal"
```
**Result**:
- ✅ SSH (22): Open to all
- ✅ Docker services: Only accessible from 192.168.200.0/24
- ✅ External web access: Through NPM proxy
- 🔒 Direct external access to Docker ports: Blocked
#### Option B: Selective External Access
**Use Case**: Specific Docker services need external access
```bash
# Example: Allow external access to ports 8080 and 9000
ansible-playbook playbooks/secure-docker-server-firewall.yml \
-e "firewall_mode=selective" \
-e "external_ports=8080,9000"
```
**Result**:
- ✅ SSH (22): Open to all
- ✅ Specified ports (8080, 9000): Open to all
- 🔒 Other Docker services: Only internal network
#### Option C: Custom Configuration
**Use Case**: You need full control
1. Test first:
```bash
ansible-playbook playbooks/secure-docker-server-firewall.yml --check
```
2. Edit the playbook:
```bash
nano playbooks/secure-docker-server-firewall.yml
# Modify docker_service_ports variable
```
3. Apply:
```bash
ansible-playbook playbooks/secure-docker-server-firewall.yml
```
## Docker Services Identification
These ports were found running on the docker server:
| Port | Service | Typical Use | Recommend |
|------|---------|-------------|-----------|
| 5000 | Docker Registry? | Container registry | Internal only |
| 8000 | Unknown | Web service | Internal only |
| 8001 | Unknown | Web service | Internal only |
| 8080 | Common web | Jenkins/Tomcat/Generic | Via NPM proxy |
| 8081 | Unknown | Web service | Internal only |
| 8082 | Unknown | Web service | Internal only |
| 8443 | HTTPS service | Web service (SSL) | Via NPM proxy |
| 9000 | Portainer/SonarQube | Container mgmt | Internal only |
| 11434 | Ollama? | AI service | Internal only |
**Recommendation**: Use NPM (nginx) at 192.168.200.71 to proxy external web traffic to internal Docker services.
## Pre-Execution Checklist
Before running the firewall configuration:
- [ ] **Identify required external access**
- Which services need to be accessed from outside?
- Can they be proxied through NPM instead?
- [ ] **Verify NPM proxy setup**
- Is NPM configured to proxy to Docker services?
- Test internal access first
- [ ] **Have backup access**
- Ensure you have console access if SSH locks you out
- Or run from the server locally
- [ ] **Test in check mode first**
```bash
ansible-playbook playbooks/secure-docker-server-firewall.yml --check
```
- [ ] **Monitor impact**
- Check Docker containers still work
- Verify internal network access
- Test external access if configured
## Execution Instructions
### Step 1: Decide on firewall mode
Ask yourself:
1. Do any Docker services need direct external access? (Usually NO)
2. Are you using NPM proxy for web services? (Recommended YES)
3. Is everything accessed from internal network only? (Ideal YES)
### Step 2: Run the appropriate command
**Most Common** (Internal only + NPM proxy):
```bash
ansible-playbook playbooks/secure-docker-server-firewall.yml
```
**If you need external access to specific ports**:
```bash
ansible-playbook playbooks/secure-docker-server-firewall.yml \
-e "firewall_mode=selective" \
-e "external_ports=8080,9000"
```
### Step 3: Verify everything works
```bash
# Check firewall status
ansible docker -m shell -a "ufw status verbose" -b
# Check Docker containers still running
ansible docker -m shell -a "docker ps" -b
# Test SSH access
ssh dlxadmin@192.168.200.200
# Test internal network access (from another internal server)
curl http://192.168.200.200:8080
# Test services work through NPM proxy (if configured)
curl http://your-service.directlx.dev
```
### Step 4: Make adjustments if needed
```bash
# View current rules
ansible docker -m shell -a "ufw status numbered" -b
# Delete a rule
ansible docker -m shell -a "ufw delete <NUMBER>" -b
# Add a new rule
ansible docker -m shell -a "ufw allow from 192.168.200.0/24 to any port 8000" -b
```
## Rollback Plan
If something goes wrong:
```bash
# Disable firewall temporarily
ansible docker -m ufw -a "state=disabled" -b
# Reset firewall completely
ansible docker -m ufw -a "state=reset" -b
# Re-enable with just SSH
ansible docker -m ufw -a "rule=allow port=22 proto=tcp" -b
ansible docker -m ufw -a "state=enabled" -b
```
## Monitoring After Configuration
```bash
# Check blocked connections
ansible docker -m shell -a "grep UFW /var/log/syslog | tail -20" -b
# Monitor active connections
ansible docker -m shell -a "ss -tnp" -b
# View firewall logs
ansible docker -m shell -a "journalctl -u ufw --since '10 minutes ago'" -b
```
## Next Steps
1. **Review this document** carefully
2. **Identify which Docker services need external access** (if any)
3. **Choose firewall mode** (internal recommended)
4. **Test in check mode** first
5. **Execute the playbook**
6. **Verify services** still work
7. **Document any port exceptions** you added

# Jenkins Server Connectivity Fix
**Date**: 2026-02-09
**Server**: jenkins (192.168.200.91)
**Issue**: Ports blocked by firewall, SonarQube containers stopped
## Problem Summary
The jenkins server had two critical issues:
1. **Firewall Blocking Ports**: UFW was configured with default settings, only allowing SSH (port 22)
- Jenkins running on port 8080 was blocked
- SonarQube on port 9000 was blocked
2. **SonarQube Containers Stopped**: Both containers had been down for 5 months
- `sonarqube` container: Exited (137)
- `postgresql` container: Exited (0)
## Root Cause
The jenkins server lacked a `host_vars/jenkins.yml` file, causing it to inherit default firewall settings from the common role that only allowed SSH access.
## Solution Applied
### 1. Created Firewall Configuration
Created `/source/dlx-src/dlx-ansible/host_vars/jenkins.yml`:
```yaml
---
# Jenkins server specific variables
# Allow Jenkins and SonarQube ports through firewall
common_firewall_allowed_ports:
- "22/tcp" # SSH
- "8080/tcp" # Jenkins Web UI
- "9000/tcp" # SonarQube Web UI
- "5432/tcp" # PostgreSQL (SonarQube database) - optional
```
### 2. Applied Firewall Rules
```bash
ansible jenkins -m community.general.ufw -a "rule=allow port=8080 proto=tcp" -b
ansible jenkins -m community.general.ufw -a "rule=allow port=9000 proto=tcp" -b
```
### 3. Restarted SonarQube Services
```bash
ansible jenkins -m shell -a "docker start postgresql" -b
ansible jenkins -m shell -a "docker start sonarqube" -b
```
## Verification
### Firewall Status
```
Status: active
To Action From
-- ------ ----
22/tcp ALLOW IN Anywhere
8080/tcp ALLOW IN Anywhere
9000/tcp ALLOW IN Anywhere
```
### Running Containers
```
CONTAINER ID IMAGE STATUS PORTS
97c85a325ed9 sonarqube:community Up 6 seconds 0.0.0.0:9000->9000/tcp
29fe0ededb3e postgres:15 Up 14 seconds 5432/tcp
```
### Listening Ports
```
Port 8080: Jenkins (Java process)
Port 9000: SonarQube (Docker container)
Port 5432: PostgreSQL (internal Docker networking)
```
## Access URLs
- **Jenkins**: http://192.168.200.91:8080
- **SonarQube**: http://192.168.200.91:9000
## Future Maintenance
### Check Container Status
```bash
ansible jenkins -m shell -a "docker ps -a" -b
```
### Restart SonarQube
```bash
ansible jenkins -m shell -a "docker restart postgresql sonarqube" -b
```
### View Logs
```bash
# SonarQube logs
ansible jenkins -m shell -a "docker logs sonarqube --tail 100" -b
# PostgreSQL logs
ansible jenkins -m shell -a "docker logs postgresql --tail 100" -b
```
### Apply Firewall Configuration via Ansible
```bash
# Apply common role with updated host_vars
ansible-playbook playbooks/site.yml -l jenkins -t firewall
```
## Notes
- PostgreSQL container only exposes port 5432 internally to Docker network (not 0.0.0.0), which is the correct configuration
- SonarQube takes 30-60 seconds to fully start up after container starts
- Jenkins is running as a system service (Java process), not in Docker
- Future updates to firewall rules should be made in `host_vars/jenkins.yml` and applied via the common role

```
Before:
Jenkins Agent → Router:22 → Jenkins:22
After (with NPM proxy):
Jenkins Agent → NPM:2222 → Jenkins:22
Centralized logging
Access control
SSL/TLS support
```
## Benefits
**Security**: Centralized access point through NPM
**Logging**: All SSH connections logged by NPM
**Flexibility**: Easy to add more agents on different ports
**SSL Support**: Can add SSL/TLS for encrypted tunneling
**Monitoring**: NPM provides connection statistics
## Next Steps After Setup
1. ✅ Complete NPM stream configuration
2. ✅ Update Jenkins agent settings
3. ✅ Test connection
4. ⏳ Update router port forwarding (if external access needed)
5. ⏳ Restrict Jenkins SSH to NPM only (optional security hardening)
6. ⏳ Set up monitoring/alerts for connection failures
## Advanced: Restrict SSH to NPM Only
For additional security, restrict Jenkins SSH to only accept from NPM:
```bash
# Allow SSH only from NPM
ansible jenkins -m community.general.ufw -a "rule=allow from=192.168.200.71 to=any port=22 proto=tcp" -b
# Remove general SSH rule (if you want strict restriction)
# ansible jenkins -m community.general.ufw -a "rule=delete port=22 proto=tcp" -b
```
⚠️ **Warning**: Only do this after confirming NPM proxy works, or you might lock yourself out!

# Jenkins SSH Agent Authentication Troubleshooting
**Date**: 2026-02-09
**Issue**: Jenkins cannot authenticate to remote build agent
**Error**: `Authentication failed` when connecting to remote SSH agent
## Problem Description
Jenkins is configured to connect to a remote build agent via SSH but authentication fails:
```
SSHLauncher{host='45.16.76.42', port=22, credentialsId='dlx-key', ...}
[SSH] Opening SSH connection to 45.16.76.42:22.
[SSH] Authentication failed.
```
## Root Cause
The SSH public key associated with Jenkins's 'dlx-key' credential is not present in the `~/.ssh/authorized_keys` file on the remote agent server (45.16.76.42).
## Quick Diagnosis
From jenkins server:
```bash
# Test network connectivity
ping -c 2 45.16.76.42
# Test SSH connectivity (should fail with "Permission denied (publickey)")
ssh dlxadmin@45.16.76.42
```
## Solution Options
### Option 1: Add Jenkins Key to Remote Agent (Quickest)
**Step 1** - Get Jenkins's public key from Web UI:
1. Open Jenkins: http://192.168.200.91:8080
2. Go to: **Manage Jenkins****Credentials****System** → **Global credentials (unrestricted)**
3. Click on the **'dlx-key'** credential
4. Look for the public key display (if available)
5. Copy the public key
**Step 2** - Add to remote agent:
```bash
# SSH to the remote agent
ssh dlxadmin@45.16.76.42
# Add the Jenkins public key
echo "ssh-rsa AAAA... jenkins@host" >> ~/.ssh/authorized_keys
chmod 600 ~/.ssh/authorized_keys
# Verify authorized_keys format
cat ~/.ssh/authorized_keys
```
**Step 3** - Test connection from Jenkins server:
```bash
# SSH to jenkins server
ssh dlxadmin@192.168.200.91
# Test connection as jenkins user
sudo -u jenkins ssh -o StrictHostKeyChecking=no dlxadmin@45.16.76.42 'echo "Success!"'
```
### Option 2: Create New SSH Key for Jenkins (Most Reliable)
**Step 1** - Run the Ansible playbook:
```bash
ansible-playbook playbooks/setup-jenkins-agent-ssh.yml -e "agent_host=45.16.76.42"
```
This will:
- Create SSH key pair for jenkins user at `/var/lib/jenkins/.ssh/id_rsa`
- Display the public key
- Create helper script to copy key to agent
**Step 2** - Copy key to agent (choose one method):
**Method A - Automatic** (if you have SSH access):
```bash
ssh dlxadmin@192.168.200.91
/tmp/copy-jenkins-key-to-agent.sh
```
**Method B - Manual**:
```bash
# Get public key from jenkins server
ssh dlxadmin@192.168.200.91 'sudo cat /var/lib/jenkins/.ssh/id_rsa.pub'
# Add to agent's authorized_keys
ssh dlxadmin@45.16.76.42
echo "<paste-public-key>" >> ~/.ssh/authorized_keys
chmod 600 ~/.ssh/authorized_keys
```
**Step 3** - Update Jenkins credential:
1. Go to: http://192.168.200.91:8080/manage/credentials/
2. Click on **'dlx-key'** credential (or create new one)
3. Click **Update**
4. Under "Private Key":
- Select **Enter directly**
- Copy content from: `/var/lib/jenkins/.ssh/id_rsa` on jenkins server
5. Save
**Step 4** - Test Jenkins agent connection:
1. Go to: http://192.168.200.91:8080/computer/
2. Find the agent that uses 45.16.76.42
3. Click **Launch agent** or **Relaunch agent**
4. Check logs for successful connection
### Option 3: Use Existing dlxadmin Key
If dlxadmin user already has SSH access to the agent:
**Step 1** - Copy dlxadmin's key to jenkins user:
```bash
ssh dlxadmin@192.168.200.91
# Copy key to jenkins user
sudo cp ~/.ssh/id_ed25519 /var/lib/jenkins/.ssh/
sudo cp ~/.ssh/id_ed25519.pub /var/lib/jenkins/.ssh/
sudo chown jenkins:jenkins /var/lib/jenkins/.ssh/id_ed25519*
sudo chmod 600 /var/lib/jenkins/.ssh/id_ed25519
```
**Step 2** - Update Jenkins credential with this key
## Verification Steps
### 1. Test SSH Connection from Jenkins Server
```bash
# SSH to jenkins server
ssh dlxadmin@192.168.200.91
# Test as jenkins user
sudo -u jenkins ssh -o StrictHostKeyChecking=no dlxadmin@45.16.76.42 'hostname'
```
Expected output: The hostname of the remote agent
### 2. Check Agent in Jenkins
```bash
# Via Jenkins Web UI
http://192.168.200.91:8080/computer/
# Look for the agent, should show "Connected" or agent should successfully launch
```
### 3. Verify authorized_keys on Remote Agent
```bash
ssh dlxadmin@45.16.76.42
cat ~/.ssh/authorized_keys | grep jenkins
```
Expected: Should show one or more Jenkins public keys
## Common Issues
### Issue: "Host key verification failed"
**Solution**: Add host to jenkins user's known_hosts:
```bash
sudo -u jenkins ssh-keyscan -H 45.16.76.42 >> /var/lib/jenkins/.ssh/known_hosts
```
### Issue: "Permission denied" even with correct key
**Causes**:
1. Wrong username (check if it should be 'dlxadmin', 'jenkins', 'ubuntu', etc.)
2. Wrong permissions on authorized_keys:
```bash
chmod 700 ~/.ssh
chmod 600 ~/.ssh/authorized_keys
```
3. SELinux blocking (if applicable):
```bash
restorecon -R ~/.ssh
```
### Issue: Jenkins shows "dlx-key" but can't edit/view
**Solution**: Credential is encrypted. Either:
- Replace with new credential
- Use Jenkins CLI to export (requires admin token)
## Alternative: Password Authentication
If SSH key auth continues to fail, temporarily enable password auth (NOT RECOMMENDED for production):
```bash
# On remote agent
sudo vim /etc/ssh/sshd_config
# Set: PasswordAuthentication yes
sudo systemctl restart sshd
# In Jenkins, update credential to use password instead of key
```
## Files and Locations
- **Jenkins Home**: `/var/lib/jenkins/`
- **Jenkins SSH Keys**: `/var/lib/jenkins/.ssh/`
- **Jenkins Credentials**: `/var/lib/jenkins/credentials.xml` (encrypted)
- **Remote Agent User**: `dlxadmin`
- **Remote Agent SSH Config**: `/home/dlxadmin/.ssh/authorized_keys`
## Related Commands
```bash
# View Jenkins credential store (encrypted)
sudo cat /var/lib/jenkins/credentials.xml
# Check jenkins user SSH directory
sudo ls -la /var/lib/jenkins/.ssh/
# Test SSH with verbose output
sudo -u jenkins ssh -vvv dlxadmin@45.16.76.42
# View SSH daemon logs on agent
journalctl -u ssh -f
# Check Jenkins logs
sudo tail -f /var/log/jenkins/jenkins.log
```
## Summary Checklist
- [ ] Network connectivity verified (ping works)
- [ ] SSH port 22 is reachable
- [ ] Jenkins user has SSH key pair
- [ ] Jenkins public key is in agent's authorized_keys
- [ ] Permissions correct (700 .ssh, 600 authorized_keys)

# NPM SSH Proxy for Jenkins Agents
**Date**: 2026-02-09
**Purpose**: Use Nginx Proxy Manager to proxy SSH connections to Jenkins agents
**Benefit**: Centralized access control, logging, and SSL termination
## Architecture
### Before (Direct SSH)
```
External → Router:22 → Jenkins:22
```
**Issues**:
- Direct SSH exposure
- No centralized logging
- Single point of failure
### After (NPM Proxy)
```
External → NPM:2222 → Jenkins:22
Jenkins Agent Config: Connect to NPM:2222
```
**Benefits**:
- ✅ Centralized access through NPM
- ✅ NPM logging and monitoring
- ✅ Easier to manage multiple agents
- ✅ Can add rate limiting
- ✅ SSL/TLS for agent.jar downloads via web UI
## NPM Configuration
### Step 1: Create TCP Stream in NPM
**Via NPM Web UI** (http://192.168.200.71:81):
1. **Login to NPM**
- URL: http://192.168.200.71:81
- Default: admin@example.com / changeme
2. **Navigate to Streams**
- Click **Streams** in the sidebar
- Click **Add Stream**
3. **Configure Incoming Stream**
- **Incoming Port**: `2222`
- **Forwarding Host**: `192.168.200.91` (jenkins server)
- **Forwarding Port**: `22`
- **TCP Forwarding**: Enabled
- **UDP Forwarding**: Disabled
4. **Enable SSL/TLS Forwarding** (Optional)
- For encrypted SSH tunneling
- **SSL Certificate**: Upload or use Let's Encrypt
- **Force SSL**: Enabled
5. **Save**
### Step 2: Update Firewall on NPM Server
The NPM server needs to allow incoming connections on port 2222:
```bash
# Run from ansible control machine
ansible npm -m community.general.ufw -a "rule=allow port=2222 proto=tcp" -b
# Verify
ansible npm -m shell -a "ufw status | grep 2222" -b
```
### Step 3: Update Jenkins Agent Configuration
**In Jenkins Web UI** (http://192.168.200.91:8080):
1. **Navigate to Agent**
- Go to: **Manage Jenkins** → **Manage Nodes and Clouds**
- Click on the agent that uses SSH
2. **Update SSH Host**
- **Host**: Change from `45.16.76.42` to `192.168.200.71` (NPM server)
- **Port**: Change from `22` to `2222`
- **Credentials**: Keep as `dlx-key`
3. **Advanced Settings**
- **JVM Options**: Add if needed: `-Djava.awt.headless=true`
- **Prefix Start Agent Command**: Leave empty
- **Suffix Start Agent Command**: Leave empty
4. **Save and Launch Agent**
### Step 4: Update Router Port Forwarding (Optional)
If you want external access through the router:
**Old Rule**:
- External Port: `22`
- Internal IP: `192.168.200.91` (jenkins)
- Internal Port: `22`
**New Rule**:
- External Port: `2222` (or keep 22 if you prefer)
- Internal IP: `192.168.200.71` (NPM)
- Internal Port: `2222`
## Testing
### Test 1: SSH Through NPM from Local Network
```bash
# Test SSH connection through NPM proxy
ssh -p 2222 dlxadmin@192.168.200.71
# Should connect to jenkins server
hostname # Should output: dlx-sonar
```
### Test 2: Jenkins Agent Connection
```bash
# From jenkins server, test as jenkins user
sudo -u jenkins ssh -p 2222 -i /var/lib/jenkins/.ssh/id_rsa dlxadmin@192.168.200.71 'hostname'
# Expected output: dlx-sonar
```
### Test 3: Launch Agent from Jenkins UI
1. Go to: http://192.168.200.91:8080/computer/
2. Find the agent
3. Click **Launch agent**
4. Check logs for successful connection
## NPM Stream Configuration File
NPM stores stream configurations in its database. For backup/reference:
```json
{
"incoming_port": 2222,
"forwarding_host": "192.168.200.91",
"forwarding_port": 22,
"tcp_forwarding": true,
"udp_forwarding": false,
"enabled": true
}
```
## Troubleshooting
### Issue: Cannot connect to NPM:2222
**Check NPM firewall**:
```bash
ansible npm -m shell -a "ufw status | grep 2222" -b
ansible npm -m shell -a "ss -tlnp | grep 2222" -b
```
**Check NPM stream is active**:
- Login to NPM UI
- Go to Streams
- Verify stream is enabled (green toggle)
### Issue: Connection timeout
**Check NPM can reach Jenkins**:
```bash
ansible npm -m shell -a "ping -c 2 192.168.200.91" -b
ansible npm -m shell -a "nc -zv 192.168.200.91 22" -b
```
**Check Jenkins SSH is running**:
```bash
ansible jenkins -m shell -a "systemctl status sshd" -b
```
### Issue: Authentication fails
**Verify SSH key**:
```bash
# Get Jenkins public key
ansible jenkins -m shell -a "cat /var/lib/jenkins/.ssh/id_rsa.pub" -b
# Check it's in authorized_keys
ansible jenkins -m shell -a "grep jenkins /home/dlxadmin/.ssh/authorized_keys" -b
```
### Issue: NPM stream not forwarding
**Check NPM logs**:
```bash
ansible npm -m shell -a "docker logs nginx-proxy-manager --tail 100" -b
# Look for stream-related errors
```
**Restart NPM**:
```bash
ansible npm -m shell -a "docker restart nginx-proxy-manager" -b
```
## Advanced: Multiple Jenkins Agents
For multiple remote agents, create separate streams:
| Agent | NPM Port | Forward To | Purpose |
|-------|----------|------------|---------|
| jenkins-local | 2222 | 192.168.200.91:22 | Local Jenkins agent |
| build-agent-1 | 2223 | 192.168.200.120:22 | Remote build agent |
| build-agent-2 | 2224 | 192.168.200.121:22 | Remote build agent |
## Security Considerations
### Recommended Firewall Rules
**NPM Server** (192.168.200.71):
```yaml
common_firewall_allowed_ports:
- "22/tcp" # SSH admin access
- "80/tcp" # HTTP
- "443/tcp" # HTTPS
- "81/tcp" # NPM Admin panel
- "2222/tcp" # Jenkins SSH proxy
- "2223/tcp" # Additional agents (if needed)
```
**Jenkins Server** (192.168.200.91):
```yaml
common_firewall_allowed_ports:
- "22/tcp" # SSH (restrict to NPM IP only)
- "8080/tcp" # Jenkins Web UI
- "9000/tcp" # SonarQube
```
### Restrict SSH Access to NPM Only
On Jenkins server, restrict SSH to only accept from NPM:
```bash
# Allow SSH only from NPM server
ansible jenkins -m community.general.ufw -a "rule=allow from=192.168.200.71 to=any port=22 proto=tcp" -b
# Deny SSH from all others (if not already default)
ansible jenkins -m community.general.ufw -a "rule=deny port=22 proto=tcp" -b
```
## Monitoring
### NPM Access Logs
```bash
# View NPM access logs
ansible npm -m shell -a "docker logs nginx-proxy-manager --tail 50 | grep stream" -b
```
### Connection Statistics
```bash
# Check active SSH connections through NPM
ansible npm -m shell -a "ss -tn | grep :2222" -b
# Check connections on Jenkins
ansible jenkins -m shell -a "ss -tn | grep :22 | grep ESTAB" -b
```
## Backup and Recovery
### Backup NPM Configuration
```bash
# Backup NPM database
ansible npm -m shell -a "docker exec nginx-proxy-manager sqlite3 /data/database.sqlite .dump > /tmp/npm-backup.sql" -b
# Download backup
ansible npm -m fetch -a "src=/tmp/npm-backup.sql dest=./backups/npm-backup-$(date +%Y%m%d).sql" -b
```
### Restore NPM Configuration
```bash
# Upload backup
ansible npm -m copy -a "src=./backups/npm-backup.sql dest=/tmp/npm-restore.sql" -b
# Restore database
ansible npm -m shell -a "docker exec nginx-proxy-manager sqlite3 /data/database.sqlite < /tmp/npm-restore.sql" -b
# Restart NPM
ansible npm -m shell -a "docker restart nginx-proxy-manager" -b
```

# Security Audit Summary
**Date**: 2026-02-09
**Servers Audited**: 16
**Full Report**: `/tmp/security-audit-full-report.txt`
## Executive Summary
Security audit completed across all infrastructure servers. Multiple security concerns identified ranging from **CRITICAL** to **LOW** priority.
## Critical Security Findings
### 🔴 CRITICAL
1. **Root Login Enabled via SSH** (`ansible-node`, `gitea`)
- **Risk**: Direct root access increases attack surface
- **Affected**: 2 servers
- **Recommendation**: Disable root login immediately
```yaml
PermitRootLogin no
```
2. **No Firewall on Multiple Servers**
- **Risk**: All ports exposed to network
- **Affected**: `ansible-node`, `gitea`, and others
- **Recommendation**: Enable UFW with strict rules
3. **Password Authentication Enabled on Jenkins**
- **Risk**: We enabled this for temporary AWS access
- **Status**: Known configuration (for AWS Jenkins Master)
- **Recommendation**: Switch to key-based auth when possible
### 🟠 HIGH
4. **Automatic Updates Not Configured**
- **Risk**: Servers missing security patches
- **Affected**: `ansible-node`, `docker`, and most servers
- **Recommendation**: Enable unattended-upgrades
5. **Security Updates Available**
- **Critical**: `docker` has **65 pending security updates**
- **Recommendation**: Apply immediately
```bash
ansible docker -m apt -a "upgrade=dist update_cache=yes" -b
```
6. **Multiple Services Exposed on Docker Server**
- **Risk**: Ports 5000, 8000-8082, 8443, 9000, 11434 publicly accessible
- **Firewall**: Currently disabled
- **Recommendation**: Enable firewall, restrict to internal network
### 🟡 MEDIUM
7. **Password-Based Users on Multiple Servers**
- **Users with passwords**: root, dlxadmin, directlx, jenkins
- **Risk**: Potential brute-force targets
- **Recommendation**: Enforce strong password policies
8. **PermitRootLogin Enabled**
- **Affected**: Several Proxmox nodes
- **Risk**: Root SSH access possible
- **Recommendation**: Disable after confirming Proxmox compatibility
## Server-Specific Findings
### ansible-node (192.168.200.106)
- ✅ Password auth: Disabled
- ❌ Root login: **ENABLED**
- ❌ Firewall: **NOT CONFIGURED**
- ❌ Auto-updates: **NOT CONFIGURED**
- Services: nginx (80, 443), MySQL (3306), Webmin (12321)
### docker (192.168.200.200)
- ✅ Root login: Disabled
- ❌ Firewall: **INACTIVE**
- ❌ Auto-updates: **NOT CONFIGURED**
- ⚠️ Security updates: **65 PENDING**
- Services: Many Docker containers on multiple ports
### jenkins (192.168.200.91)
- ✅ Firewall: Active (ports 22, 8080, 9000, 2222)
- ⚠️ Password auth: **ENABLED** (intentional for AWS)
- ⚠️ Keyboard-interactive: **ENABLED** (intentional)
- Services: Jenkins (8080), SonarQube (9000)
### npm (192.168.200.71)
- ✅ Firewall: Active (ports 22, 80, 443, 81, 2222)
- ✅ Password auth: Disabled
- Services: Nginx Proxy Manager, OpenResty
### hiveops, smartjournal, odoo
- ⚠️ Firewall: **DISABLED** (intentional for Docker networking)
- ❌ Auto-updates: **NOT CONFIGURED**
- Multiple Docker services running
### Proxmox Nodes (proxmox-00, 01, 02)
- ✅ Firewall: Active
- ⚠️ Root login: Enabled (may be required for Proxmox)
- Services: Proxmox web interface
## Immediate Actions Required
### Priority 1 (Critical - Do Now)
1. **Disable Root SSH Login**
```bash
ansible all -m lineinfile -a "path=/etc/ssh/sshd_config regexp='^PermitRootLogin' line='PermitRootLogin no'" -b
ansible all -m service -a "name=sshd state=restarted" -b
```
2. **Apply Security Updates on Docker Server**
```bash
ansible docker -m apt -a "upgrade=dist update_cache=yes" -b
```
3. **Enable Firewall on Critical Servers**
```bash
# For servers without firewall
ansible ansible-node,gitea -m apt -a "name=ufw state=present" -b
ansible ansible-node,gitea -m ufw -a "rule=allow port=22 proto=tcp" -b
ansible ansible-node,gitea -m ufw -a "state=enabled" -b
```
### Priority 2 (High - This Week)
4. **Enable Automatic Security Updates**
```bash
ansible all -m apt -a "name=unattended-upgrades state=present" -b
ansible all -m copy -a "dest=/etc/apt/apt.conf.d/20auto-upgrades content='APT::Periodic::Update-Package-Lists \"1\";\nAPT::Periodic::Unattended-Upgrade \"1\";' mode=0644" -b
```
5. **Configure Firewall for Docker Server**
```bash
ansible docker -m ufw -a "rule=allow port={{ item }} proto=tcp" -b
# Add specific ports needed for services
```
6. **Review and Secure Open Ports**
- Audit what services need external access
- Close unnecessary ports
- Use NPM proxy for web services
### Priority 3 (Medium - This Month)
7. **Implement Password Policy**
```yaml
# In /etc/login.defs
PASS_MAX_DAYS 90
PASS_MIN_DAYS 1
PASS_MIN_LEN 12
PASS_WARN_AGE 7
```
8. **Enable Fail2Ban**
```bash
ansible all -m apt -a "name=fail2ban state=present" -b
```
9. **Regular Security Audit Schedule**
- Run monthly: `ansible-playbook playbooks/security-audit-v2.yml`
- Review findings
- Track improvements
## Positive Security Practices Found
**Jenkins Server**: Well-configured firewall with specific ports
**NPM Server**: Good firewall configuration, SSL certificates managed
**Most Servers**: Password SSH auth disabled (key-only)
**Most Servers**: Root login restricted
**Proxmox Nodes**: Firewalls active
## Recommended Playbooks
### security-hardening.yml (To Be Created)
```yaml
- Enable automatic security updates
- Disable root SSH login (except where needed)
- Configure UFW on all servers
- Install fail2ban
- Set password policies
- Remove world-writable files
```
### security-monitoring.yml (To Be Created)
```yaml
- Monitor failed login attempts
- Alert on unauthorized access
- Track open ports
- Monitor security updates
```
## Compliance Checklist

```
proxmox-00 (Control Hub):
├── local (62 GB) ⚠️ CRITICAL: 84.5% FULL
├── dlx-sda (1.9 TB) - 3.3% used
├── dlx-sdb ZFS (1.9 TB) - 0.2% used
├── dlx-sdf4 LVM (785 GB) - 20.5% used
└── local-lvm (116 GB) - 0% used
proxmox-01 (Docker/Services):
├── local (62 GB) - 69.5% used
├── dlx-docker (718 GB) ⚠️ HIGH: 81.1% USED
└── local-lvm (116 GB) - 0% used
proxmox-02 (Development):
├── local (92 GB) - 47.2% used
├── dlx-data (702 GB) - 9.1% used (NVME, fast)
└── local-lvm (160 GB) - 0% used
```

## Capacity & Utilization Summary
| Metric | Value | Status |
|--------|-------|--------|
| **Total Capacity** | ~17 TB | ✓ Adequate |
| **Total Used** | ~1.3 TB | ✓ 7.6% |
| **Total Available** | ~15.7 TB | ✓ Healthy |
| **Shared NFS** | 9.7 TB (2.2% used) | ✓ Excellent |
| **Local Storage** | 7.3 TB (18.3% used) | ⚠️ Mixed |
---
## Critical Issues & Recommendations
### 🔴 CRITICAL: proxmox-00 Root Filesystem
**Issue**: `/` (root) is 84.5% full (52.6 GB of 62 GB)
**Impact**:
- System may become unstable
- Package installation may fail
- Logs may stop being written
**Recommendation**:
1. Clean up old logs: `journalctl --vacuum=time:30d`
2. Check for old snapshots/backups
3. Consider moving `/var` to separate storage
4. Monitor closely for growth
---
### 🟠 HIGH PRIORITY: proxmox-01 dlx-docker
**Issue**: dlx-docker storage at 81.1% capacity (568 GB of 718 GB)
**Impact**:
- Limited room for container growth
- Risk of running out of space during operations
**Recommendation**:
1. Audit running containers: `docker ps -a --format "{{.Names}}: {{json .SizeRw}}"`
2. Remove unused images/layers
3. Consider expanding partition or migrating data
4. Set up monitoring for capacity
---
### 🟠 HIGH PRIORITY: proxmox-01 dlx-sonar
**Issue**: SonarQube using 354 GB (82% of allocated 422 GB)
**Impact**:
- Large analysis database
- May need separate storage strategy
**Recommendation**:
1. Review SonarQube retention policies
2. Archive old analysis data
3. Consider separate backup strategy
---
### ⚠️ Medium Priority: Storage Inconsistency
**Issue**: Disabled storage backends across nodes
| Backend | disabled on | Notes |
|---------|-------------|-------|
| dlx-docker | proxmox-00, 02 | Only enabled on 01 |
| dlx-data | proxmox-00, 01 | Only enabled on 02 |
| dlx-sda | proxmox-01 | Enabled on 00 only |
| dlx-sdb (ZFS) | proxmox-01, 02 | Only enabled on 00 |
| dlx-sdf4 (LVM) | proxmox-01, 02 | Only enabled on 00 |
**Recommendation**:
1. Document why each backend is disabled per node
2. Standardize storage configuration across cluster
3. Consider cluster-wide storage policy
---
### ⚠️ Medium Priority: Container Lifecycle
**Issue**: 15 containers are stopped but still allocating space (1.2 TB total)
**Recommendation**:
1. Audit stopped containers (dlx-swarm-*, dlx-kube-*, etc.)
2. Delete unused containers to reclaim space
3. Document intended purpose of stopped containers
---
## Recommendations Summary
### Immediate (Next week)
1. ✅ Compress logs on proxmox-00 root filesystem
2. ✅ Audit dlx-docker usage and remove unused images
3. ✅ Monitor proxmox-01 dlx-docker capacity
### Short-term (1-2 months)
1. Expand dlx-docker partition or migrate high-usage containers
2. Archive SonarQube data or increase disk allocation
3. Clean up stopped containers or document their retention
### Long-term (3-6 months)
1. Implement automated capacity monitoring
2. Standardize storage backend configuration across cluster
3. Establish storage lifecycle policies (snapshots, backups, retention)
4. Consider tiered storage strategy (fast NVME vs. slow SATA)
---
## Storage Performance Tiers
Based on hardware analysis:
| Tier | Storage | Speed | Use Case |
|------|---------|-------|----------|
| **Tier 1 (Fast)** | nvme0n1 (proxmox-02) | NVMe | OS, critical services |
| **Tier 2 (Medium)** | ZFS/LVM pools | HDD/SSD | VMs, container data |
| **Tier 3 (Shared)** | NFS mounts | Network | Backups, shared data |
| **Tier 4 (Archive)** | Large local dirs | HDD | Infrequently accessed |
**Optimization Opportunity**: Align hot data to Tier 1, cold data to Tier 3

# Storage Remediation Guide
**Generated**: 2026-02-08
**Status**: Critical issues identified - Remediation playbooks created
**Priority**: 🔴 HIGH - Immediate action recommended
---
## Overview
Four critical storage issues have been identified in the Proxmox cluster:
| Issue | Severity | Current | Target | Playbook |
|-------|----------|---------|--------|----------|
| proxmox-00 root FS | 🔴 CRITICAL | 84.5% | <70% | remediate-storage-critical-issues.yml |
| proxmox-01 dlx-docker | 🟠 HIGH | 81.1% | <75% | remediate-docker-storage.yml |
| SonarQube disk usage | 🟠 HIGH | 354 GB | Archive data | remediate-storage-critical-issues.yml |
| Unused containers | ⚠️ MEDIUM | 1.2 TB allocated | Cleanup | remediate-stopped-containers.yml |
Corresponding **remediation playbooks** have been created to automate fixes.
---
## Remediation Playbooks
### 1. `remediate-storage-critical-issues.yml`
**Purpose**: Address immediate critical issues on proxmox-00 and proxmox-01
**What it does**:
- Compresses old journal logs (>30 days)
- Removes old syslog files (>90 days)
- Cleans apt cache and temp files
- Prunes Docker images, volumes, and build cache
- Audits SonarQube usage
- Lists stopped containers for manual review
**Expected results**:
- proxmox-00 root: Frees ~10-15 GB
- proxmox-01 dlx-docker: Frees ~20-50 GB
**Execution**:
```bash
# Dry-run (safe, shows what would be done)
ansible-playbook playbooks/remediate-storage-critical-issues.yml --check
# Execute on specific host
ansible-playbook playbooks/remediate-storage-critical-issues.yml -l proxmox-00
```
**Time estimate**: 5-10 minutes per host
---
### 2. `remediate-docker-storage.yml`
**Purpose**: Deep cleanup of Docker storage on proxmox-01
**What it does**:
- Analyzes Docker container sizes
- Lists Docker images by size
- Finds dangling images and volumes
- Removes unused Docker resources
- Configures automated weekly cleanup
- Sets up hourly monitoring
**Expected results**:
- Removes unused images/layers
- Frees 50-150 GB depending on usage
- Prevents regrowth with automation
**Execution**:
```bash
# Dry-run first
ansible-playbook playbooks/remediate-docker-storage.yml -l proxmox-01 --check
# Execute
ansible-playbook playbooks/remediate-docker-storage.yml -l proxmox-01
```
**Time estimate**: 10-15 minutes
---
### 3. `remediate-stopped-containers.yml`
**Purpose**: Safely remove unused LXC containers
**What it does**:
- Lists all stopped containers
- Calculates disk allocation per container
- Creates configuration backups before removal
- Safely removes containers (with dry-run mode)
- Provides recovery instructions
**Expected results**:
- Removes 1-2 TB of unused container allocations
- Allows recovery via backed-up configs
**Execution**:
```bash
# DRY RUN (no deletion, default)
ansible-playbook playbooks/remediate-stopped-containers.yml --check
# To actually remove (set dry_run=false)
ansible-playbook playbooks/remediate-stopped-containers.yml \
-e dry_run=false
# Remove specific containers only
ansible-playbook playbooks/remediate-stopped-containers.yml \
-e 'containers_to_remove=[{vmid: 108, name: dlx-mysql-02}]' \
-e dry_run=false
```
**Safety features**:
- Backups created before removal: `/tmp/pve-container-backups/`
- Dry-run mode by default (set `dry_run=false` to execute)
- Manual approval on each container
**Time estimate**: 2-5 minutes
---
### 4. `configure-storage-monitoring.yml`
**Purpose**: Set up continuous monitoring and alerting
**What it does**:
- Creates monitoring scripts for filesystem, Docker, containers
- Installs cron jobs for continuous monitoring
- Configures syslog integration
- Sets alert thresholds (75%, 85%, 95%)
- Provides Prometheus metrics export
- Creates cluster status dashboard command
**Expected results**:
- Real-time capacity monitoring
- Alerts before running out of space
- Integration with monitoring tools
**Execution**:
```bash
# Deploy monitoring to all Proxmox hosts
ansible-playbook playbooks/configure-storage-monitoring.yml -l proxmox
# View cluster status
/usr/local/bin/storage-monitoring/cluster-status.sh
# View alerts
tail -f /var/log/storage-monitor.log
```
**Time estimate**: 5 minutes
---
## Execution Plan
### Phase 1: Preparation (Before running playbooks)
#### 1. Verify backups exist
```bash
# Check backup location
ls -lh /var/backups/
```
#### 2. Review current state
```bash
# Check filesystem usage
df -h /
df -h /mnt/pve/*
# Check Docker usage (proxmox-01 only)
docker system df
# List containers
pct list | head -20
qm list | head -20
```
#### 3. Document baseline
```bash
# Capture baseline metrics
ansible proxmox -m shell -a "df -h /" -u dlxadmin > baseline-storage.txt
```
---
### Phase 2: Execute Remediation
#### Step 1: Test with dry-run (RECOMMENDED)
```bash
# Test critical issues fix
ansible-playbook playbooks/remediate-storage-critical-issues.yml \
--check -l proxmox-00
# Test Docker cleanup
ansible-playbook playbooks/remediate-docker-storage.yml \
--check -l proxmox-01
# Test container removal
ansible-playbook playbooks/remediate-stopped-containers.yml \
--check
```
Review output before proceeding to Step 2.
#### Step 2: Execute on proxmox-00 (Critical)
```bash
# Clean up root filesystem and logs
ansible-playbook playbooks/remediate-storage-critical-issues.yml \
-l proxmox-00 -v
```
**Verification**:
```bash
# SSH to proxmox-00
ssh dlxadmin@192.168.200.10
df -h /
# Should show: from 84.5% → 70-75%
du -sh /var/log
# Should show: smaller size after cleanup
```
#### Step 3: Execute on proxmox-01 (High Priority)
```bash
# Clean Docker storage
ansible-playbook playbooks/remediate-docker-storage.yml \
-l proxmox-01 -v
```
**Verification**:
```bash
# SSH to proxmox-01
ssh dlxadmin@192.168.200.11
df -h /mnt/pve/dlx-docker
# Should show: from 81% → 60-70%
docker system df
# Should show: reduced image/volume sizes
```
#### Step 4: Remove Stopped Containers (Optional)
```bash
# First, verify which containers will be removed
ansible-playbook playbooks/remediate-stopped-containers.yml \
--check
# Review output, then execute
ansible-playbook playbooks/remediate-stopped-containers.yml \
-e dry_run=false -v
```
**Verification**:
```bash
# Check backup location
ls -lh /tmp/pve-container-backups/
# Verify stopped containers are gone
pct list | grep stopped
```
#### Step 5: Enable Monitoring
```bash
# Configure monitoring on all hosts
ansible-playbook playbooks/configure-storage-monitoring.yml \
-l proxmox
```
**Verification**:
```bash
# Check monitoring scripts installed
ls -la /usr/local/bin/storage-monitoring/
# Check cron jobs
crontab -l | grep storage
# View monitoring logs
tail -f /var/log/storage-monitor.log
```

## Rollback Plan
If something goes wrong, you can roll back:
### Restore Filesystem from Snapshot
```bash
# If you have LVM snapshots
lvconvert --merge /dev/mapper/pve-root_snapshot
# Or restore from backup
proxmox-backup-client restore /mnt/backups/...
```
### Recover Deleted Containers
```bash
# Restore from backed-up config
pct restore /tmp/pve-container-backups/container-108-dlx-mysql-02.conf 108
# Start container
pct start 108
```
### Restore Docker Images
```bash
# Pull images from registry
docker pull image:tag
# Or restore from backup
docker load < image-backup.tar
```
---
## Monitoring & Validation
### Daily Checks
```bash
# Monitor storage trends
tail -f /var/log/storage-monitor.log
# Check cluster status
/usr/local/bin/storage-monitoring/cluster-status.sh
# Alert check
grep ALERT /var/log/storage-monitor.log
```
### Weekly Verification
```bash
# Run storage audit
ansible-playbook playbooks/remediate-storage-critical-issues.yml --check
# Review Docker logs
docker system df
# List containers by size
pct list | while read line; do
vmid=$(echo $line | awk '{print $1}')
name=$(echo $line | awk '{print $2}')
size=$(du -sh /var/lib/lxc/$vmid 2>/dev/null | awk '{print $1}')
echo "$vmid $name $size"
done | sort -k3 -hr
```
### Monthly Audit
```bash
# Update storage audit report
ansible-playbook playbooks/remediate-storage-critical-issues.yml --check -v
# Generate updated metrics
pvesh get /nodes/proxmox-00/storage | grep capacity
# Compare to baseline
diff baseline-storage.txt <(ansible proxmox -m shell -a "df -h /" -u dlxadmin)
```
---
## Troubleshooting
### Issue: Root filesystem still full after cleanup
**Symptoms**: `df -h /` still shows >80%
**Solutions**:
1. Check for large files: `find / -size +1G 2>/dev/null`
2. Check Docker: `docker system prune -a`
3. Check logs: `du -sh /var/log/* | sort -hr | head`
4. Expand partition (if necessary)
### Issue: Docker cleanup removed needed image
**Symptoms**: Container fails to start after cleanup
**Solution**: Rebuild or pull image
```bash
docker pull image:tag
docker-compose up -d
```
### Issue: Removed container was still in use
**Recovery**: Restore from backup
```bash
# List available backups
ls -la /tmp/pve-container-backups/
# Restore to new VMID
pct restore /tmp/pve-container-backups/container-108-dlx-mysql-02.conf 200
pct start 200
```

2. CHECK DEPENDENCIES:
- Is dlx-mysql-01 running and taking load?
- Are swarm/kube services actually needed?
- Is wireguard currently in use?

If removing MySQL replicas:
- Check that dlx-mysql-01 is healthy
- Verify replication is not in progress
- Confirm no active connections from replicas

To safely remove stopped containers:
1. VERIFY PURPOSE: Document why each was created
2. CHECK BACKUPS: Ensure data is backed up elsewhere
3. EXPORT CONFIG: pct config VMID > backup.conf
4. DELETE: pct destroy VMID --force
Example safe removal script:
---
# Backup container config before deletion
pct config 105 > /tmp/dlx-wireguard-backup.conf
pct destroy 105 --force
# This frees 32 GB immediately
