Note
GitHub-hosted runners are not currently supported on GitHub Enterprise Server. You can see more information about planned future support on the GitHub public roadmap.
Introduction
This tutorial demonstrates how to use the GitHub CLI in a workflow to label newly opened or reopened issues. For example, you can add the triage
label every time an issue is opened or reopened. Then, you can see all issues that need to be triaged by filtering for issues with the triage
label.
The GitHub CLI allows you to easily use the GitHub API in a workflow.
In the tutorial, you will first make a workflow file that uses the GitHub CLI. Then, you will customize the workflow to suit your needs.
Creating the workflow
-
Choose a repository where you want to apply this project management workflow. You can use an existing repository that you have write access to, or you can create a new repository. For more information about creating a repository, see "Creating a new repository."
-
In your repository, create a file called
.github/workflows/YOUR_WORKFLOW.yml
, replacingYOUR_WORKFLOW
with a name of your choice. This is a workflow file. For more information about creating new files on GitHub, see "Creating new files." -
Copy the following YAML contents into your workflow file.
YAML name: Label issues on: issues: types: - reopened - opened jobs: label_issues: runs-on: ubuntu-latest permissions: issues: write steps: - run: gh issue edit "$NUMBER" --add-label "$LABELS" env: GH_TOKEN: ${{ secrets.GITHUB_TOKEN }} GH_REPO: ${{ github.repository }} NUMBER: ${{ github.event.issue.number }} LABELS: triage
name: Label issues on: issues: types: - reopened - opened jobs: label_issues: runs-on: ubuntu-latest permissions: issues: write steps: - run: gh issue edit "$NUMBER" --add-label "$LABELS" env: GH_TOKEN: ${{ secrets.GITHUB_TOKEN }} GH_REPO: ${{ github.repository }} NUMBER: ${{ github.event.issue.number }} LABELS: triage
-
Customize the
env
values in your workflow file:- The
GH_TOKEN
,GH_REPO
, andNUMBER
values are automatically set using thegithub
andsecrets
contexts. You do not need to change these. - Change the value for
LABELS
to the list of labels that you want to add to the issue. The label(s) must exist for your repository. Separate multiple labels with commas. For example,help wanted,good first issue
. For more information about labels, see Managing labels.
- The
-
Commit your workflow file to the default branch of your repository. For more information, see "Creating new files."
Testing the workflow
Every time an issue in your repository is opened or reopened, this workflow will add the labels that you specified to the issue.
Test out your workflow by creating an issue in your repository.
- Create an issue in your repository. For more information, see Creating an issue.
- To see the workflow run that was triggered by creating the issue, view the history of your workflow runs. For more information, see Viewing workflow run history.
- When the workflow completes, the issue that you created should have the specified labels added.
