1. SSH Connection

Quick Connect

ssh automation@69.62.108.82
# Or with alias
ssh srv759970

SSH Config (~/.ssh/config)

Host srv759970
    HostName 69.62.108.82
    User automation
    IdentityFile ~/.ssh/id_ed25519
    IdentitiesOnly yes
    ServerAliveInterval 60

Fix Permission Denied (Windows)

$keyPath = "$env:USERPROFILE\.ssh\id_ed25519"
$acl = Get-Acl $keyPath
$acl.SetAccessRuleProtection($true, $false)
$acl.Access | ForEach-Object { $acl.RemoveAccessRule($_) | Out-Null }
$user = [System.Security.Principal.WindowsIdentity]::GetCurrent().Name
$rule = New-Object System.Security.AccessControl.FileSystemAccessRule($user, "FullControl", "Allow")
$acl.AddAccessRule($rule)
Set-Acl $keyPath $acl

2. System Status

Quick Status Check

ssh srv759970 'free -h && df -h && uptime'

Disk Space

ssh srv759970 'df -h | grep -E "Filesystem|/dev/"'
ssh srv759970 'du -sh /opt/* 2>/dev/null | sort -rh | head -10'

Thresholds: < 20 GB = Warning, < 10 GB = Critical

Memory Usage

ssh srv759970 'free -h'
ssh srv759970 'docker stats --no-stream --format "table {{.Name}}\t{{.MemUsage}}" | head -15'

Services Status

ssh srv759970 'docker ps --format "table {{.Names}}\t{{.Status}}"'
ssh srv759970 'systemctl status nginx docker'
ssh srv759970 'pm2 list'

3. Weekly Maintenance

Docker Cleanup (Safe)

ssh srv759970 << 'EOF'
echo "=== Docker Cleanup ==="
docker system df
docker image prune -f
docker volume prune -f
docker system df
EOF

Never run docker system prune -a (breaks auto-start)

System Health Check

ssh srv759970 << 'EOF'
echo "=== Health Check ==="
df -h /
free -h
docker ps -a --filter "status=exited" --format '{{.Names}}'
sudo certbot certificates | grep -E "Certificate Name|Expiry Date"
EOF

---

4. Space Reclamation

Phase 1: Safe Cleanup (No approval needed)

ssh srv759970 << 'EOF'
# Dangling images (~1GB)
docker image prune -f

# Journal logs (~400MB)
sudo journalctl --vacuum-size=100M

# Safe log cleanup
sudo truncate -s 0 /var/log/rclone-music.log
sudo truncate -s 0 /var/log/nginx-auto-docker.log
EOF

Phase 2: Moderate Cleanup (Ask user first)

# Old Docker images (>30 days)
docker image prune -a --filter 'until=720h'

# Unused volumes
docker volume prune -f

Emergency Cleanup (< 5 GB available)

ssh srv759970 << 'EOF'
# Find large files
find /opt -type f -size +100M -exec ls -lh {} \; 2>/dev/null | head -20

# Large container logs
find /var/lib/docker/containers -name "*-json.log" -exec ls -lh {} \; | sort -k5 -hr | head -10

# Aggressive cleanup
docker system prune -f
sudo apt clean
EOF

5. Troubleshooting

SSH Connection Issues

| Problem | Solution | |---------|----------| | Permission denied | Fix key permissions (see above) | | Connection timeout | Check ping 69.62.108.82 | | Host key changed | ssh-keygen -R 69.62.108.82 |

View Logs

ssh srv759970 'sudo journalctl -n 100 --no-pager'

Automation User Restrictions

CAN: Docker, Nginx, services, SSL, packages, file permissions CANNOT: Reboot, shutdown, modify sudo config
