This should facilitiate development of Conduit modules on the host, while making use of a locally deployed container-based Conduit instance.

Spin up a dockerized Conduit deployment, then start your microservice with the following env vars:
SERVICE_URL: host.docker.internal:XXXXX (specifying an available port)
URL_REMAP: 0.0.0.0

Notes:

  • container gRPC service ports should be exposed
  • Linux systems need: --add-host=host.docker.internal:host-gateway
  • Remote deployments are not supported

I've updated the compose file so that it includes the solution for Linux users.
I kept the service port exports commented out so as not keep failure points to a minimum for the vast majority of users.
I also updated all the port related envs to match internal/external ports (as we only update the address part).

Ideally, I'll handle optionally exposing the ports through the CLI using a single compose file.
