image

image resource is used to add a reference to a Docker image to your pipeline.

You can create a image resource by adding it to shippable.yml.

resources:
  - name:           <string>
    type:           image
    integration:    <string>
    pointer:        <object>
    seed:           <object>
  • name -- should be an easy to remember text string

  • type -- is set to image

  • integration -- name of the subscription integration, i.e. the name of your integration at https://app.shippable.com/subs/[github or bitbucket]/[Subscription name]/integrations. Currently supported integration types are

  • pointer -- is an object that contains integration specific properties

      pointer:
        sourceName: <fully qualified image name, can be just repo/image for Docker Hub>
    
  • seed -- is an object that contains initial version properties

      seed:
        versionName: <image tag>

To make it easy to use these environment variables, the platform provides a command line utility that can be used to work with these values.
