How do I hook jbpm up to kie-server for REST API usage?

[NullVoxPopuli]

I was reading: #29
and I was able to get the two showcase containers running.

docker run -p 8080:8080 -p 8001:8001 -d -e JAVA_OPTS="-Djava.net.preferIPv4Stack=true" --name jbpm-workbench jboss/jbpm-workbench-showcase:latest

docker run -p 8180:8080 -d --name kie-server -e JAVA_OPTS="-Djava.net.preferIPv4Stack=true" --link jbpm-workbench:kie_wb jboss/kie-server-showcase:latest

at http://localhost:8080/jbpm_console, I create a workflow, and deploy it and make sure the start checkbox is checked on deploy.

However, when I visit http://localhost:8180/kie-server/services/rest/server/containers

<response type="SUCCESS" msg="List of created containers">
  <kie-containers/>
</response>

My deployed project doesn't show up?
does kie not know how to communicate with jbpm?

docker logs <kie-server container id> shows a toooooon of exceptions:

13:27:14,414 ERROR [org.kie.server.remote.rest.jbpm.QueryDataResource] (default task-10) Unexpected error during processing Can't get metadata on specified data set: jbpmProcessInstances: org.dashbuilder.dataset.exception.DataSetLookupException: Can't get metadata on specified data set: jbpmProcessInstances

Is there a guide anywhere to correctly get things working?

I feel a lot of the documentation for kie and jbpm assumes some knowledge of how kie and friends are supposed to interact with each other. I don't know much, but all I want is to have a rest api into jbpm.

Is there a volume that needs to be shared between the two docker containers?

I also have this docker-compose setup:

version: '3.4'
services:
  jbpm:
    image: jboss/jbpm-workbench-showcase
    ports:
      - '8080:8080'
      - '8081:8081'
      - '9990:9990'
    networks:
      - backoffice
    volumes:
      - type: bind
        source: ./deployment/local/config/niogit
        target: /opt/jboss/wildfly/bin/.niogit

  kie-server:
    image: jboss/kie-server-showcase
    ports:
      - '8180:8080'
    links:
      - jbpm:kie_wb
    networks:
      - backoffice

  backoffice:

Thanks!

Please re-try with jboss/kie-server-showcase is 7.7.0.Final-4 (latest) and let us know if it happens again.
If so, please send a mail to drools-setup or
drools-usage as there are more people reading.

well, I don't get any errors.
though, I've since learned that jbpm and kie-server need to share an .m2 directory for jbpm to deploy processes to.

version: '3.4'
services:
  jbpm:
    build:
      context: ./source/workflow-engine/jbpm-workbench
      dockerfile: Dockerfile
    ports:
      - '8080:8080'
      - '8081:8081'
      - '9990:9990'
    networks:
      - backoffice
    volumes:
      - type: volume
        source: jbpm-m2
        target: /opt/jboss/.m2
      - type: bind
        source: ./deployment/local/config/niogit
        target: /opt/jboss/wildfly/bin/.niogit

  kie-server:
    build:
      context: ./source/workflow-engine/kie-server
      dockerfile: Dockerfile
    ports:
      - '8180:8080'
    links:
      - jbpm:kie_wb
    networks:
      - backoffice
    volumes:
      - type: volume
        source: jbpm-m2
        target: /opt/jboss/.m2

volumes:
  jbpm-m2:

networks:
  internet:
  backoffice:

However, I still can't get the containers endpoint on the kie-server to show anything other than an empty list.
