Notify

Drone uses the notify section of the .drone.yml to configure notification steps. Drone does not have any built-in notification capabilities. This functionality is outsourced to plugins. See the plugin marketplace for a list of official plugins.

An example configuration that sends a Slack notification on build completion:

notify:
  slack:
    webhook_url: https://hooks.slack.com/services/f10e2821bbb/200352313bc
    channel: dev
    username: drone

Notification conditions

Use the when attribute to limit execution to a specific branch:

publish:
  slack:
    when:
      branch: master

Or limit execution based on the build status. The below example will only send the notification when the build fails:

publish:
  slack:
    when:
      success: false
      failure: true
