   docker_manage: stop -> containerName: [container]
   

3. Remove old container:

   docker_manage: remove -> containerName: [container]
   

4. Start new container:

   vps_execute_command: docker run -d --name [container] -p 8080:80 [image]
   

5. Verify:

   docker_manage: logs -> containerName: [container], tail: 50

Parameters:
  command: |
    mkdir -p /backups
    tar -czf /backups/config-backup-$(date +%Y%m%d-%H%M%S).tar.gz \

      /etc/letsencrypt \
      /var/www

Check Security Updates

Action: vps_execute_command
Parameters:
  command: apt list --upgradable | grep -i security

Troubleshooting

High Memory Usage

1. Check top processes: ps aux --sort=-%mem | head -n 10
2. Check Docker containers: docker stats --no-stream
3. Clear caches if needed: sync && echo 3 > /proc/sys/vm/drop_caches

Service Not Responding

1. Check service status: systemctl status [service]
2. Check logs: journalctl -u [service] -n 100
3. Try restart: systemctl restart [service]
4. Check port availability: netstat -tuln | grep [port]

Disk Full

1. Check usage: df -h
2. Find large files: du -sh /* | sort -h
3. Clean Docker: docker system prune -af
4. Clean logs: journalctl --vacuum-time=7d

Container Issues

1. Check container logs: docker logs [container]
2. Inspect container: docker inspect [container]
3. Check resource limits: docker stats [container]
4. Restart if needed: docker restart [container]

Security Best Practices

• Always use sudo for privileged operations
• Review commands before executing destructive operations
• Keep backups before major changes
• Monitor logs for suspicious activity
• Keep system and packages updated
• Use Docker security best practices
• Limit exposed ports

Error Handling

• Permission Denied: Ensure using sudo for privileged operations
• Command Not Found: Check if required software is installed
• Docker Daemon Not Running: Start Docker service
• Out of Disk Space: Clean up logs and unused containers/images
• Service Failed to Start: Check logs for specific error messages

Notes

• Always backup before making significant changes
• Test commands in non-production first when possible
• Monitor system resources after changes
• Keep documentation of configurations
• Use version control for important files
• Schedule regular maintenance tasks
