How to dynamically specify a docker image to load as a service

Jonas De Beukelaer

Hey!

I'm trying to use a docker image, built in step 1, as a service in step 2.

The docker image name is defined by the short commit sha, so the docker image url has to be dynamically set.

Is there any way to do this?

Or would I have to define a static image name (e.g. :testing) to use specifically for this pipeline?

pipelines:
  branches:
    master:
      - step:
          image: go:something
          script:
            - # test go code
            - # build docker image with tag=short_commit_sha (7chars)
      - step:
          image: acceptance_tester_image
          script:
            - # test api server image using service api-server
          services:
            - api-server
definitions:
  services:
    api-server:
      image:
        name: IMAGE/I/BUILT/IN/STEP/ONE:short_commit_sha
options:
  docker: true

This feature is currently not supported in Pipelines. There's an open feature request for adding support for environment variables in Docker image names that you can follow if you're interested.

Using Docker Compose is the way to go here! It's an intentional use-case we had for providing Docker in Docker.

The associated issues with Docker in Docker are ones that the Pipelines team has to stay on top of. They (mostly) won't affect you when using Docker inside of Pipelines. So feel free to use Docker as much as you'd like.
