GitHub Pull-Request Comment [Drone Plugin]

This plugin can be used for posting customized messages on GitHub pull requests (like sending back test results). You will have to create a GitHub App and install it in your repository. Provide Read & Write access on Issues and Pull Requests to the app. For authentication and authorizations, this plugin will use private key from the created GitHub App.

Below configuration demonstrates simple usage:

steps:
- name: pr_comment
  image: rustycl0ck/drone-pr-comment
  settings:
    rsa_key:
      from_secret: pr_rsa_key
    app_id:
      from_secret: pr_app_id
    comment_file: test-results.txt
  when:
    event:
    - pull_request

Comments can be read as inline text as well:

    settings:
      rsa_key:
        from_secret: pr_rsa_key
      app_id:
