Override entrypoint in Codeship service's image

Question

I'm working with a multi-stage image which builds and tests the service in the build process and it works fine with the push steps. The only problem is that I don't want to push the image every time a build of the feature branch is sent to Codeship, so I have this in my codeship-steps.yaml:

 - name: Build API
    type: serial
    steps:
    - name: Build API image
      tag: ^(feature)
      service: api
      command: true
    - name: Push staging API image
      tag: ^(develop)
      type: push
      service: api
      image_name: gcr.io/project/api
      image_tag: "{{.CommitID}}"
      registry: https://gcr.io
      dockercfg_service: staging-gcr
    - name: Push production API image
      tag: ^(master)
      type: push
      service: api
      image_name: gcr.io/project/api
      image_tag: "{{.CommitID}}"
      registry: https://gcr.io
      dockercfg_service: production-gcr

and this in codeship-services.yaml:

api:
  build:
    image: singularities/codeship-api
    dockerfile: api/Dockerfile

Everything should work fine, but the Build API image step fails because it try to run the service like docker run. Is there any way to override the entrypoint or tell Codeship to only build the image like docker build?

Answer 1

In the case of entrypoint scripts, my suggestion would be to create an argument that allows the script to exit successfully.

If you'd like, you can send your steps/services/Dockerfile(s)/entrypoint script to [email protected] and we will take a closer look.
