How to just build a Docker image?

[niclashedam]

Hello,

I would like to just build a Docker image based on the Dockerfile. When I try, the build fails due to some ruby gem stuff.
bundle install --gemfile=$SHIPPABLE_GEMFILE $SHIPPABLE_BUNDLER_ARGS

My YML file:

build:
  post_ci:
    - docker commit web eu.gcr.io/........
    - docker push eu.gcr.io/........

integrations:
  hub:
    - integrationName: gcr
      type: gcr
      branches:
        only:
          - production

@niclashedam this is because when your ci section is empty we run default commands for ruby language.

To skip the default command you can include something in your ci section as shown below-

build:
  ci:
    - pwd 
  post_ci:
    - docker commit web eu.gcr.io/........
    - docker push eu.gcr.io/........

integrations:
  hub:
    - integrationName: gcr
      type: gcr
      branches:
        only:
          - production
