Plugins are docker containers that encapsulate commands, and can be shared and re-used in your pipeline. Use plugins to build and publish artifacts, send notifications, and more.

Example Slack plugin:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14
15


kind: pipeline
type: docker
name: default

steps:
- name: build
  image: node
  commands:
  - npm install
  - npm test

- name: notify
  image: plugins/slack
  settings:
    webhook: https://hooks.slack.com/services/...

As you can see plugins are just Docker containers. Anyone can encapsulate logic, bundle as a Docker image, and publish to a Docker registry to share with their organization, or with the broader community.

The Drone community owns the "plugins" namespace in Dockerhub. Plugins in this namespace are collectively maintained by the Drone community.

Secrets

Drone provides the ability to source any configuration parameter from a named secret using the from_secret syntax.
