A simple Go web server that executes docker-compose commands via webhook.

1. Configure the server port and commands in config.yaml
2. Run the server with go run main.go
3. The server exposes:
   • GET /health - Health check endpoint
   • POST /update - Webhook to trigger docker-compose commands

Edit config.yaml to set the port and list of docker-compose commands to run when the update endpoint is called.

You can also build and run the application using Docker:

docker build -t runner-app .
docker run -v ./config:/app/config -v ./compose:/app/compose -p 8080:8080 runner-app

This will mount your local config directory to /app/config and compose directory to /app/compose in the container, allowing the application to access your configuration and docker-compose files.

Alternatively, use the provided docker-compose.yml to run the application:

docker-compose up -d

This will build and start the Runner application in the background with the same volume mounts as the Docker command.

Important Note: The Runner application executes docker-compose commands, which must be installed and available on the host system or in the environment where the commands are expected to run. If you are running the application in a Docker container, ensure that docker-compose is installed on the host, or consider mounting the Docker socket (/var/run/docker.sock) into the container to interact with the host's Docker daemon directly (with appropriate permissions and security considerations). The provided docker-compose.yml includes this mounting by default.

Be sure to read up on what mounting /var/run/docker.sock means from a security standpoint before running!

Here's a sample docker-compose.yml for running the Runner app:

version: '3.8'
services:
  runner:
    image: ghcr.io/pangobit/runner:latest
    container_name: runner-app
    ports:
      - "${PORT:-8080}:8080"
    volumes:
      - ./config:/app/config
      - ./compose:/app/compose
      - /var/run/docker.sock:/var/run/docker.sock
    environment:
      - PORT=${PORT:-8080}
    restart: unless-stopped

You can copy this configuration into your own docker-compose.yml file or modify it as needed to suit your environment.
