Web service on Docker deployments is exposed even if port is not specified (for Traefik usage)

The ports property is just to expose a port, but if you don’t expose anything, the container still has an open port (where NodeJS is running), and Traefik can connect to it internally through Docker’s networking

Through a Traefik label you can specify the port where Traefik should connect to, here’s how Wappler do it:

labels:
  - 'traefik.http.services.my-project__staging_web.loadbalancer.server.port=3000

Io socket.io not working when used with Redis and Traefik

Maybe something like this, untested Docker-compose networks: networks: default: ~ proxy: name: 'wappler-compose_proxy' external: true And Redis service: redis: image: 'redis:alpine' # Remember to set Redis version hostname: 'redis' networks: - default volumes: - 'redis-volume:/data' Web service, relevant excerpt: web: networks: - default - proxy The project’s network I named “default”, which would be what docker-compose would create for e…
