Azure DevOps pipeline tasks for GitHub

Tasks to manage labels in a GitHub pull request from Azure DevOps Pipeline.

Usage

• Add a label to indicate whether or not a CI build succeeded
• Add a label to indicate that a build is being processed

Requirements

• Only for PR triggered builds condition: eq(variables['Build.Reason'], 'PullRequest')
• Source code repository is hosted in GitHub
• Labels must already be defined in GitHub. This extension only applies them.

Examples

Adding a label

- task: fbeltrao.GitHubPRLabel.custom-build-release-task.GitHubPRLabel@0
  condition: eq(variables['Build.Reason'], 'PullRequest') # only run step if it is a PR
  displayName: 'GitHub PR label (add ci-succeeded)'
  inputs:
    action: 'add'
    gitHubConnection: myGitHubConnection
    label: ci-succeeded

Removing a label

- task: fbeltrao.GitHubPRLabel.custom-build-release-task.GitHubPRLabel@0
  condition: eq(variables['Build.Reason'], 'PullRequest') # only run step if it is a PR
  displayName: 'GitHub PR label (remove ci-succeeded)'
  inputs:
    action: 'remove'
    gitHubConnection: myGitHubConnection
    label: ci-succeeded

Checking if a label exists using bash

  # Find out if full ci is enabled for Pull Request validation
  - bash: |
     echo "Looking for label at https://api.github.com/repos/$BUILD_REPOSITORY_ID/issues/$SYSTEM_PULLREQUEST_PULLREQUESTNUMBER/labels"
     if curl -s "https://api.github.com/repos/$BUILD_REPOSITORY_ID/issues/$SYSTEM_PULLREQUEST_PULLREQUESTNUMBER/labels" | grep '"name": "fullci"'
     then
       echo "##vso[task.setvariable variable=prWithCILabel;isOutput=true]true"
       echo "fullci label found!"
     fi
    displayName: Check for CI label build on PR
    condition: eq(variables['Build.Reason'], 'PullRequest')
    name: checkPrCILabel
