Pipeline actions

Actions enable event-based pipeline execution, such as triggering a pipeline launch with a GitHub webhook whenever the pipeline repository is updated. Seqera Platform currently offers support for native GitHub webhooks and a general Tower webhook that can be invoked programmatically.

GitHub webhooks​

A GitHub webhook listens for any changes made in the pipeline repository. When a change occurs it triggers the launch of the pipeline automatically.

You must sign in to Seqera using GitHub authentication to create a GitHub webhook action. If you're signed in via Google the Add button in step 6 below will be inactive.

To create a new action, select the Actions tab and select Add Action.

  1. Enter a Name for your action.
  2. Select GitHub webhook as the Event source.
  3. Select the Compute environment where the pipeline will be executed.
  4. Select the Pipeline to launch and (optionally) the Revision number.
  5. Enter the Work directory, the Config profiles, and the Pipeline parameters.
  6. Select Add.

The pipeline action is now set up. When a new commit occurs for the selected repository and revision, an event is triggered and the pipeline is launched.

Workspace maintainers can edit pipeline actions. Select Edit from the options menu to the right of the action on the Actions list to load the action details.

Select Update to save the updated pipeline action.

Workspace maintainers can edit the names of existing pipeline actions from the Edit Action page.

Tower launch hooks​

A Tower launch hook creates a custom endpoint URL which can be used to trigger the execution of your pipeline programmatically from a script or web service.

To create a new action, select the Actions tab and select Add Action.

  1. Enter a Name for your action.
  2. Select Tower launch hook as the event source.
  3. Select the Compute environment to execute your pipeline.
  4. Enter the Pipeline to launch and (optionally) the Revision number.
  5. Enter the Work directory, the Config profiles, and the Pipeline parameters.
  6. Select Add.

The pipeline action is now set up and the new endpoint can be used to launch the corresponding pipeline programmatically.

When you create a Tower launch hook, you also create an access token for launching pipelines. Access tokens can be managed on the tokens page, which is also accessible from the navigation menu.
