traefik template missing network name

[craniac-pr]

Hi Christian

seems the traefik template fails to give a name to the docker network, this for boilerplates version 0.1.3

docker compose config
returns
yaml: while parsing a block mapping at line 50, column 3: did not find expected key

note the missing network name in lines 30, 47, 51 in the generated yaml

Next Steps

Start the traefik project

1 Copy the project directory for traefik to the host.
2 Start Traefik with Docker Compose from the project directory: docker compose up -d

Came here to report the same issue. Also worth noting that networks: at line 32 is missing a string value. Here is the exact error docker compose shows me when I try to run this:

validating /opt/docker_containers/traefik/compose.yaml: services.traefik.networks.0 must be a string
