Triggers on subscriptions


Currently trigger build supports only a push style where one need to explicitly define other pipeline to trigger. This style is limiting; it would be good if trigger build also support subscription based type of syntax where other pipeline can simply reference the original pipeline to get trigger.


Something like this?

  - pipeline: "some-pipeline-slug"
    event: "started|blocked|completed|succeeded|failed"

  - command: "buildkite pipeline upload"
