Plugins are tasks that run during a workflow but are not part of the main workflow. Plugins can be treated as just another task, however, plugins do not have completion or failure detection.
Example definition of a plugin:
plugins:
monitor:
image: ghcr.io/galleybytes/monitor:latest
imagePullPolicy: IfNotPresent
when: After
task: setup
The above plugin task will run after the setup task has completed.
Alternatively, a plugin can be triggered to start at the same time of another task. For example:
plugins:
monitor:
image: ghcr.io/galleybytes/monitor:latest
imagePullPolicy: IfNotPresent
when: At
task: setup
Each plugin is run once per generation. Plugins that are older than the current generation are automatically reaped.
