Command "rabbitmq-plugins enable rabbitmq_management" fails with "Error: noproc"

Hello Atlassian Community!

My team has a continuous integration pipeline that includes some RabbitMQ tests.
Our bitbucket-pipelines.yml file looks like this:

image: python:3.6.8
pipelines:
  default:
    - step:
      name: Run Tests
      caches:
        - pip
      script:
        - pip install -r requirements.txt
        - apt-get update
- apt-get install -y rabbitmq-server
        - rabbitmq-server -detached
        - sleep 2
        - rabbitmq-plugins enable rabbitmq_management
        - sleep 2
        - rabbitmqctl stop
        - sleep 2
        - rabbitmq-server -detached
        - python tests.py

Around 50% of the time we get the following error:

<span><br>The following plugins have been enabled:<br></span><span>mochiweb<br></span><span>webmachine<br></span><span>rabbitmq_web_dispatch<br></span><span>amqp_client<br></span><span>rabbitmq_management_agent<br></span><span>rabbitmq_management</span><span><br><br>Applying plugin configuration to rabbit@90a65858-035c-4b74-be6b-a0e43bb508d1... failed.<br></span><span>Error: noproc</span><span>+ rabbitmq-plugins enable rabbitmq_management</span>

Re-running the pipeline generally "fixes" the problem. But this is eating away at our build minutes, and is quite frustrating to constantly re-run failed pipelines.

We added some `sleep` commands in there to try and slow things down, but thats obviously not working as intended, because we keep getting the "Error: noproc"

I'm hopeful that we are just "holding it wrong" but after lots of googling and experimentation its not clear to me what were doing wrong.

Thanks in advance for any help/guidance you can give us.
Please let me know if I can add any additional info that might be helpful.

Thanks!

Hi @john_mccabe

Have you thought about creating a docker image with the configuration you need and publishing it into docker hub? It would save you some time spend installing and configuring stuff.

Regarding the error you see, I would say you have to talk to rabbitmq people. They probably help you to find a way to check when the server will be ready to be used, so you can avoid the intermittent failures.
