Docker Compose Remote Management API

This is a very simple API to manage Docker compose applications via HTTP requests and receive logs via WebSockets.

Installation

Clone the repository
Create a virtual environment using python -m venv venv (python 3.12+ is required)
Activate the virtual environment using source venv/bin/activate
Install the dependencies using pip install -r requirements.txt
Create a config.json file in the projects root directory. See the config.json section for more information.
Run the API using the start.sh script
- It may be required to make the script executable using chmod +x start.sh
The API should now run on port 9090

To set up a system-wide service, you can use the compose-remote-manager.service-unit-file-template.

Usage

The API provides the following endpoints:

GET /services - returns a list of all services that are accessible with a given access key
GET /status/{service} - returns true if the service is running, false otherwise
POST /start/{service} - runs docker compose up -d in the service directory (starts the service)
POST /stop/{service} - runs docker compose down in the service directory (stops the service)
GET /logs/{service} - returns the logs of the service (docker compose logs) format into an array of 3-tuples of the form (service, timestamp, log), where service is the name of the service as defined in the docker-compose.yml file.
WS /ws/logs/{service} - establishes a WebSocket connection to the service and returns the logs as they are generated. Does not include old logs.
POST /command/{service} - runs a custom command in the service directory. The command should be passed as a JSON object in the request body. For example: {"command": "ls -la"}. The response will be the output of the command.

The {service} parameter is the name of the service as defined in the config.json file.

To access services that require an access key, append the query parameter access_key to the request. For example: /logs/<service>?access_key=1234567890

Configuring the API

The config.json file contains the configuration for the docker compose applications and the access keys to access those applications. It should be in the following format:

{
    // These are variable keys that can be used to restrict access to certain services
    "access-keys": {
        "general": "1234567890"
        ...
    },
    // The services that should be accassible via the API
    "services": {
        // The name of the service
        "service-name": {
            // The path to the directory where the docker-compose.yml file is located
            "cwd": "/path/to/dir",
            // The access key that is required to access this service. If not specified, no access key is required
            "access-key": "$general" // <- This is a variable name
        },
        "another-service": {
            "cwd": "/path/to/dir",
            "access-key": "1234567890",
            // The name of the docker-compose file (default: docker-compose.yml)
            "compose-file": "docker-compose.prod.yml"
        },
        "third-service": {
            "cwd": "/path/to/dir",
              
            // It's also possible to use a list of access keys (logical OR)
            "access-key": [
                "abc",
                "def",
            ]
        },
        "forth-service": {
          "cwd": "/path/to/dir",

          // It's also possible to restrict an access key to certain scopes
          "access-key": {
            "key": "$general",  // Specify the key
            "scope": [          // Restrict to specific scopes
                "logs",
                "status"
            ] 
          }
        }
        ...
    }
}

For the access-key field you can either use a string or a variable name (prefixed with a $ sign) that is defined in the access-keys field. To use an access key, that starts with a $ sign, you have to escape it with a another $ sign. For example: $$general would require ...?access_key=$general.

An example config.json file can be found here.

Note on Docker compose services

Currently, it's not possible to start / stop / monitor single services defined in the docker-comopse.yml file. Only all services at once can be controlled.
