All operations are performed via SSH, requiring only standard SSH and Docker tools on both client and server. ## Quick Start ```bash # Start services docker_compose_up host=192.168.1.100 user=root path=/opt/myapp # Check status docker_compose_ps host=192.168.1.100 user=root path=/opt/myapp # View logs docker_compose_logs host=192.168.1.100 user=root path=/opt/myapp tail=50 # Update and restart docker_compose_update host=192.168.1.100 user=root path=/opt/myapp pull=always ``` ## Actions ### docker_compose_up Start Docker Compose services in detached mode. **Parameters:** - `host` (required): Remote SSH host (IP or hostname) - `user` (required): SSH username - `path` (required): Directory containing docker-compose.yml - `port` (optional, default: 22): SSH port - `key_path` (optional): SSH private key path - `timeout` (optional, default: 60): Operation timeout in seconds **Example:** ``` docker_compose_up host=192.168.1.100 user=admin path=/opt/app port=2222 ``` ### docker_compose_down Stop and remove containers, networks, and volumes defined in docker-compose.yml. **Parameters:** Same as `up` **Example:** ``` docker_compose_down host=192.168.1.100 user=admin path=/opt/app ``` ### docker_compose_start Start specific stopped services. **Parameters:** - All `up` parameters - `service` (optional): Service name to start (starts all if not specified) **Example:** ``` docker_compose_start host=192.168.1.100 user=admin path=/opt/app service=web ``` ### docker_compose_stop Stop running services without removing them. **Parameters:** - All `up` parameters - `service` (optional): Service name to stop (stops all if not specified) **Example:** ``` docker_compose_stop host=192.168.1.100 user=admin path=/opt/app service=worker ``` ### docker_compose_restart Restart services. **Parameters:** - All `up` parameters - `service` (optional): Service name to restart **Example:** ``` docker_compose_restart host=192.168.1.100 user=admin path=/opt/app service=api ``` ### docker_compose_ps List all containers with their status. **Parameters:** Same as `up` **Example:** ``` docker_compose_ps host=192.168.1.100 user=admin path=/opt/app ``` ### docker_compose_logs Fetch and display logs from services. **Parameters:** - All `up` parameters - `service` (optional): Filter logs to specific service - `tail` (optional, default: 100): Number of lines to show - `follow` (optional, default: false): Stream logs continuously **Example:** ``` docker_compose_logs host=192.168.1.100 user=admin path=/opt/app tail=50 follow=true ``` ### docker_compose_update Pull the latest images and restart services. **Parameters:** - All `up` parameters - `force_recreate` (optional, default: false): Force recreate containers - `pull` (optional): Image pull policy (never, always, missing) - `command` (optional): Custom command to execute instead of default "pull && up" **Example:** ``` # Default behavior docker_compose_update host=192.168.1.100 user=admin path=/opt/app pull=always # Custom command docker_compose_update host=192.168.1.100 user=admin path=/opt/app command="sh ./upgrade.sh" ``` ### docker_compose_exec Execute a command in a running container. **Parameters:** - All `up` parameters - `service` (required): Container name to execute in - `command` (required): Command to execute - `timeout` (optional, default: 60): Command execution timeout **Example:** ``` docker_compose_exec host=192.168.1.100 user=admin path=/opt/app service=web command="ls -la /app" ``` ## Implementation Notes - SSH connections use key-based authentication by default - Always change to the correct directory before running docker compose commands - Use `-d` flag for detached mode when starting services - Handle SSH connection timeouts and authentication failures gracefully - Return structured output with success/failure status and relevant logs - Include error context when operations fail ## Error Handling Common errors and handling: 1. **SSH connection refused**: Verify host, port, and network access 2. **Authentication failed**: Check SSH key path and permissions 3. **Path not found**: Ensure docker-compose.yml exists at specified path 4. **Docker not running**: Verify Docker daemon is accessible on remote host 5. **Permission denied**: Check user has access to Docker socket ## Deployment Configuration This skill supports a `deploy-apps.json` configuration file that maps your remote hosts and applications. The Agent automatically reads this configuration to resolve host aliases, app names, SSH credentials, and file paths. ### Configuration File The structure of the `deploy-apps.json` file should be as follows: ```json { "hosts": { "<host-alias>": { "host": "remote.server.com", "description": "Server description", "base-dir": "/path/to/docker", "user": "ssh-user", "apps": { "<app-name>": { "description": "Application description", "update-command": "Custom command to execute update" } } } } } ``` ### How It Works When you reference a host alias or app name, the Agent: 1. Reads `deploy-apps.json` to find the matching configuration 2. Resolves `host` to the actual SSH hostname/IP 3. Constructs `path` from `<base-dir>/<app-name>` 4. Uses the configured `user` for SSH authentication ### Configuration Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `hosts.<alias>.host` | string | Yes | Remote SSH hostname or IP | | `hosts.<alias>.base-dir` | string | Yes | Base directory containing app folders | | `hosts.<alias>.user` | string | Yes | SSH username | | `hosts.<alias>.description` | string | No | Human-readable description | | `hosts.<alias>.apps.<name>.description` | string | Yes* | App description | | `hosts.<alias>.apps.<name>.update-command` | string | Yes* | Custom command to execute update | ### Path Resolution Example With: - `base-dir`: `/data/docker` - `app-name`: `mysql` The resolved path would be: `/data/docker/mysql` ## See Also - [Usage Reference](references/README.md) - Detailed parameter documentation - [Examples](examples/docker-remote.json) - Command examples - [Deployment Configuration](examples/deploy-apps.json) - Example configuration file
