Containers

The Containers page in OpenPanel allows you to manage Docker services defined via Docker Compose files by your Administrator.

This section provides a clear overview of your containerized services and their resource usage.

Requirements​

To access this feature:

• The Docker module must be enabled server-wide by an Administrator.
• Your account must have the Docker feature enabled.

Overview​

At the top of the page, you'll see:

• Running Containers / Total Containers – Indicates how many services are currently active.
• Total CPU – Number of CPU cores assigned to your hosting plan.
• Total Memory – Amount of RAM (in GB) assigned to your hosting plan.

You can allocate portions of these total resources to individual services.

Container Table​

Each row in the table represents a containerized service and displays:

• Name – Name of the Docker service, along with the image used and its tag (version).
• CPU Usage
  • Graph – Real-time usage as a percentage of the allocated CPU.
  • Usage – How much CPU the container is using from its allocated amount.
  • Allocated – Number of CPU cores allocated to the service.
• Memory Usage
  • Graph – Real-time usage as a percentage of the allocated memory.
  • Usage – RAM used by the service from its allocated amount.
  • Allocated – Memory (in GB) allocated to the service.
• Actions
  • Shows whether the service is Enabled or Disabled.
  • Clicking the status toggles it.
  • If the service is running, a Terminal link appears — click it to open a web terminal (docker exec) for that container.

Editing Resources​

To change CPU or Memory limits for a service:

1. Hover over the Allocated value in the table.
2. Click the pencil icon.
3. Adjust the value in the input field.
4. Click Save.

OpenPanel will check whether you have available resources to make this change. If valid, the container will restart automatically with the new limits.

Adding New Services​

At the moment, new services can only be added by the Administrator.
