Open a Canton Console to a Docker Compose-hosted CN validator node?

Questions
1

I have a 0.3.5 bundle of the Docker-Compose Based Deployment of a Validator Node running on my workstation. How do I open a Canton Console for remote administration of the participant node within that network.

Here is what I’m doing on my Mac. I’d welcome simplifying suggestions.

  1. In the docker-compose/validator folder, run source .env to set the environment variable IMAGE_REPO.
  2. Set the IMAGE_TAG environment variable, as was done when setting up the Docker Compose cluster.
  3. Create a canton-console.conf file with the following:
     canton {
   features.enable-preview-commands = yes
   remote-participants {
     participant {
       ledger-api {
         address = participant
         port = 5001
       }
       admin-api {
         address = participant
         port = 5002
       }
     }
   }
 }
  4. Identify the Docker network name with the following. For me, the network name is splice-validator_splice_validator.
    docker inspect splice-validator-participant-1 \
  | jq '.[0].NetworkSettings.Networks | keys.[0]'
  5. Launch the Canton Console with something like the following:
     docker run -it --rm \
   --network splice-validator_splice_validator \
   --volume ./:/host/ \
   --entrypoint '/app/bin/canton' \
   ${IMAGE_REPO}canton:${IMAGE_TAG} \
   -Dlogback.statusListenerClass=ch.qos.logback.core.status.NopStatusListener \
   --log-level-root WARN \
   --config /host/canton-console.conf
  6. Confirm success by running participant.health.status within the Canton Console.
Sample results 
 docker run -it --rm \
   --network splice-validator_splice_validator \
   --volume ./:/host/ \
   --entrypoint '/app/bin/canton' \
   ${IMAGE_REPO}canton:${IMAGE_TAG} \
   -Dlogback.statusListenerClass=ch.qos.logback.core.status.NopStatusListener \
   --log-level-root WARN \
   --config /host/canton-console.conf
