Adding a trigger resource to your shippable.yml gives you a way to trigger a job in your Assembly Line whenever you commit a change to that resource. This resource can be used used as an IN input for any job.

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

  - name:           <string>
    type:           trigger
      counter:      <number>
  • name -- should be an easy to remember text string

  • type -- is set to trigger

  • version -- is an object which contains specific properties that apply to this resource

          counter: 1

    The counter should be updated each time you want to trigger the jobs that have this resource as an input.

Used in Jobs

This resource is used as an IN for any type of job.

Default Environment Variables

Whenever trigger is used as an IN for a runSh or runCI job, a set of environment variables is automatically made available that you can use in your scripts.

<NAME> is the the friendly name of the resource with all letters capitalized and all characters that are not letters, numbers or underscores removed. For example, my-key-1 will be converted to MYKEY1, and my_key_1 will be converted to MY_KEY_1.

Environment variable Description
<NAME>_NAME The name of the resource.
<NAME>_ID The ID of the resource.
<NAME>_TYPE The type of the resource. In this case trigger.
<NAME>_OPERATION The operation of the resource; either IN or OUT.
<NAME>_PATH The directory containing files for the resource.
<NAME>_VERSIONID The ID of the version of the resource being used.
<NAME>_VERSIONNUMBER The number of the version of the resource being used.

Shippable Utility Functions

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.

How to use these utility functions is documented here.
