How to bind ports for docker container in bitbucket pipelines?

Conor S

I have a more detailed question with more attempts here, but in summary, I have a dev docker image which runs all the services I need in order for tests to pass.

docker run -it -p 3000:3000 -p 6379:6379 -p 8983:8983 my_dockerhub/image
 ./start_services.sh
 bundle exec rspec
 # everything passes

I'd like to run these tests withing bitbucket pipelines. I tried using this container directly with this in my bitbucket-pipelines.yml:

image: 
 name: my_dockerhub/image
 username: $DOCKER_HUB_USERNAME
 password: $DOCKER_HUB_PASSWORD
 email: $DOCKER_HUB_EMAIL
 # bind ports here somehow?

pipelines:
 branches:
 '{master, develop, bitbucket_pipelines}':
 - step:
 name: Test
 script:
 - ./start_services.sh
 - sleep 30
 - bundle exec rspec

But I get the following error at the ```bundle exec rspec``` step

# Errno::ECONNREFUSED:
 # Connection refused - connect(2) for "127.0.0.1" port 8983

How can I bind ports within the image so the tests pass?

I'm running redis and solr on custom ports. The thing that finally got it working for me was 

docker run -id -p 3000:3000 -p 6379:6379 -p 8983:8983 -v $PWD:$work_dir $my_image

 -d to run in detached mode

-i to keep stdin open, even if detached
