How to get docker service locally to debug pipeline.

Chris Taylor_16j5j1

I'm trying to debug my pipeline locally.

My bitbucket-pipelines.yml uses services. I can get everything up and running OK with a database service linked to atlassian/default-image:2 as per this article https://support.atlassian.com/bitbucket-cloud/docs/debug-pipelines-locally-with-docker/.

However, I need the docker service also.  Image atlassian/default-image:2 doesn't appear to have 'docker in docker'.  How can I acquire a docker service?

# bitbucket-pipelines.yml
image: atlassian/default-image:2
pipelines:
    default:
        - step:
            services:
                - docker # how do I get a docker service?
                - db
            script:
                # my steps here requiring both db and docker services

definitions:
    services:
        db:
            image: mysql:5.7 
            variables: 
                MYSQL_DATABASE: 'pipelines' 
                MYSQL_RANDOM_ROOT_PASSWORD: 'yes' 
                MYSQL_USER: 'test_user' 
                MYSQL_PASSWORD: 'test_user_password'

Hi Chris,

One thing you can do here is add the following option to the command that starts your main container:

-v /var/run/docker.sock:/var/run/docker.sock

This way, the Docker container you start will have access to the Docker daemon of the host system (your machine).

If you are using atlassian/default-image:2 image you will need to install Docker to the container once it starts running, you can find instructions here:

• https://docs.docker.com/engine/install/ubuntu/

Afterwards you'll be able to execute Docker commands and can proceed with the execution of commands in your script.

Is this something that works for you?

Kind regards,
Theodora
