Docker Swarm tool:

• REST API for service updates
• Automatic service discovery via Docker Tags
• Cloudflare Tunnel integration with DNS management
• Pushover notifications for service updates
• Prometheus metrics

1. Copy the .env.example file to .env and fill in the values.
2. Deploy the swarmctl server to the swarm cluster. Example: docker-compose.swarmctl.yml file.

After the swarmctl server is deployed, you can use it to update the services in the swarm cluster.

curl -X POST -H "Authorization: your-token" https://swarmctl.your-domain.com/v1/update/your-service?image=your-image

3. Add docker labels to the services you want to update. Example:

labels:
    - "cloudflared.tunnel.enabled=true"
    - "cloudflared.tunnel.port=80"
    - "cloudflared.tunnel.hostname=your-domain.com"

It also supports multiple hostnames. Example:

labels:
    - "cloudflared.tunnel.enabled=true"
    - "cloudflared.tunnel.port=80"
    - "cloudflared.tunnel.0.hostname=your-domain.com"
    - "cloudflared.tunnel.1.hostname=2.your-domain.com"

4. Deploy the services to the swarm cluster.

docker stack deploy -c docker-compose.yml your-stack

5. If you want to use the Prometheus metrics, you can use the following URL:

http://swarmctl.your-domain.com/metrics
