cloudflared-with-auto-dns-route

A variant of cloudflared image that configures dns route according to the provided tunnel-config.yml.

Usage

You may use one of the following way to configure DNS routes to your services. You may also specify CLOUDFLARED_HOSTNAME / CLOUDFLARED_SERVICE and mount tunnel-config.yml, but in this case the routing specified by environment variables is inserted at the beginning of the ingress list.

Whichever option you may choose, cloudflared container should ask you to login to Cloudflare upon docker compose up.

Mounting tunnel-config.yml

Replace <mount-base> with your preffered path (either absolute, or relative from workdir of docker compose), then write

<mount-base>/tunnel-config.yml:

ingress:
  - hostname: host1.example.com
    service: http://local-service-1:8080
  - hostname: host2.example.com
    service: http://local-service-2:8081
  - service: http_status:404

where local-service-1 and local-service2 are serving some HTTP contents.

docker-compose.yml:

Now mount your tunnel-config.yml to /etc/cloudflared/tunnel-config.yml:

volumes:
  cloudflared-home:

services:
  cloudflared:
    image: "ghcr.io/giganticminecraft/cloudflared-with-auto-dns-route"
    volumes:
      - cloudflared-home:/root
      - <mount-base>/tunnel-config.yml:/etc/cloudflared/tunnel-config.yml
    environments:
      TUNNEL_NAME: example-tunnel-1

Using a pair of environment variables

docker-compose.yml:

volumes:
  cloudflared-home:

services:
  cloudflared:
    image: "ghcr.io/giganticminecraft/cloudflared-with-auto-dns-route"
    environment:
      CLOUDFLARED_HOSTNAME: host1.example.com
      CLOUDFLARED_SERVICE: http://local-service-1:8080
    volumes:
      - cloudflared-home:/root
    environments:
      TUNNEL_NAME: example-tunnel-1
