# Container Management

Containers are the core concept of Docker, being running instances of images. Through the container management page, you can create, start, stop, and manage containers.

## Container List

Go to the **Container** page, which displays the container list by default.

The list displays the following information:

- **Container Name**: Name of the container
- **Status**: Running status switch
- **Image**: Image used by the container
- **Ports**: Port mapping (host port -> container port)
- **Running Status**: Detailed running status information
- **Actions**: Terminal, logs, rename, etc.

## Create Container

Click the **Create Container** button to open the creation dialog.

### Basic Settings

- **Container Name**: Optional, auto-generated if left empty
- **Image**: Docker image name, e.g., `nginx`, `mysql:8.4`, `your_username/your_image:tag`
- **Network**: Select the network for the container to use
- **Restart Policy**: Restart behavior after container exits
    - None: Do not auto restart
    - always: Always restart
    - on-failure: Restart on failure
    - unless-stopped: Restart unless manually stopped

### Advanced Options

- **TTY (-t)**: Allocate a pseudo-TTY
- **STDIN (-i)**: Keep STDIN open
- **Auto Remove**: Automatically delete container when stopped
- **Privileged Mode**: Grant container full system privileges (use with caution)

### Port Mapping

Map container internal ports to host ports, format: `host_port:container_port`

For example: `8080:80` means mapping container port 80 to host port 8080.

### Volume Mounts

Mount host directories or data volumes to the container, format: `host_path:container_path`

For example: `/opt/ace/data:/data` means mounting the host's `/opt/ace/data` directory to the container's `/data` directory.

### Resource Limits

Limit the CPU and memory resources the container can use.

### Environment Variables

Set container environment variables, format: `KEY=VALUE`

## Container Operations

### Batch Operations

After selecting multiple containers, you can perform batch operations:

- **Start**: Start selected containers
- **Stop**: Stop selected containers
- **Restart**: Restart selected containers
- **Force Stop**: Force stop selected containers
- **Pause**: Pause selected containers
- **Resume**: Resume paused containers
- **Delete**: Delete selected containers

### Single Container Operations

- **Terminal**: Open the container's terminal to execute commands inside the container
- **Logs**: View container runtime logs
- **Rename**: Modify container name
- **More**: View details, export, and other operations

## Clean Containers

Click **Clean Containers** to delete all stopped containers and free up system resources.

::: warning Note
The cleanup operation cannot be undone. Please ensure stopped containers are no longer needed.
