Quickstart for GitHub Actions

Try out the core features of GitHub Actions in minutes.

Remarque

Les exécuteurs hébergés sur GitHub ne sont pas pris en charge sur GitHub Enterprise Server. Vous pouvez voir plus d’informations sur le support futur planifié dans la GitHub public roadmap.

Introduction

GitHub Actions est une plateforme d’intégration continue et livraison continue (CI/CD) qui vous permet d’automatiser votre pipeline de génération, de test et de déploiement. You can create workflows that run tests whenever you push a change to your repository, or that deploy merged pull requests to production.

This quickstart guide shows you how to use the user interface of GitHub to add a workflow that demonstrates some of the essential features of GitHub Actions.

Pour commencer à utiliser les flux de travail préconfigurés, parcourez la liste des modèles dans le référentiel actions/starter-workflows. Pour plus d’informations, consultez « Using workflow templates ».

For an overview of GitHub Actions workflows, see À propos des workflows. If you want to learn about the various components that make up GitHub Actions, see Understanding GitHub Actions.

Using workflow templates

GitHub fournit des modèles de flux de travail préconfigurés que vous pouvez utiliser tels quels ou personnaliser pour créer votre propre flux de travail. GitHub analyse votre code et vous affiche des modèles de flux de travail qui pourraient être utiles pour votre référentiel. Par exemple, si votre référentiel contient du code Node.js, vous verrez des suggestions de projets Node.js.

Ces modèles de workflow sont conçus pour vous aider à être rapidement opérationnel, en offrant une gamme de configurations telles que :

Utilisez ces workflows comme point de départ pour générer votre propre workflow ou utilisez-les tels quels. Vous pouvez parcourir la liste complète des modèles de flux de travail dans le référentiel actions/starter-workflows.

Prerequisites

This guide assumes that:

Creating your first workflow

  1. In your repository on GitHub, create a workflow file called github-actions-demo.yml in the .github/workflows directory. To do this:

    • If the .github/workflows directory already exists, navigate to that directory on GitHub, click Add file, then click Create new file, and name the file github-actions-demo.yml.

    • If your repository doesn't have a .github/workflows directory, go to the main page of the repository on GitHub, click Add file, then click Create new file, and name the file .github/workflows/github-actions-demo.yml. This creates the .github and workflows directories and the github-actions-demo.yml file in a single step.

    Remarque

    For GitHub to discover any GitHub Actions workflows in your repository, you must save the workflow files in a directory called .github/workflows.

    You can give the workflow file any name you like, but you must use .yml or .yaml as the file name extension. YAML is a markup language that's commonly used for configuration files.

  2. Copy the following YAML contents into the github-actions-demo.yml file:

    YAML
    name: GitHub Actions Demo
    run-name: ${{ github.actor }} is testing out GitHub Actions 🚀
    on: [push]
    jobs:
      Explore-GitHub-Actions:
        runs-on: ubuntu-latest
        steps:
          - run: echo "🎉 The job was automatically triggered by a ${{ github.event_name }} event."
          - run: echo "🐧 This job is now running on a ${{ runner.os }} server hosted by GitHub!"
          - run: echo "🔎 The name of your branch is ${{ github.ref }} and your repository is ${{ github.repository }}."
          - name: Check out repository code
            uses: actions/checkout@v4
          - run: echo "💡 The ${{ github.repository }} repository has been cloned to the runner."
          - run: echo "🖥️ The workflow is now ready to test your code on the runner."
          - name: List files in the repository
            run: |
              ls ${{ github.workspace }}
          - run: echo "🍏 This job's status is ${{ job.status }}."
    

    At this stage you don't need to understand the details of this workflow. For now, you can just copy and paste the contents into the file. After completing this quickstart guide, you can learn about the syntax of workflow files in À propos des workflows, and for an explanation of GitHub Actions contexts, such as ${{ github.actor }} and ${{ github.event_name }}, see Accès à des informations contextuelles sur l’exécution d’un workflow.

  3. Click Commit changes.

  4. In the "Propose changes" dialog, select either the option to commit to the default branch or the option to create a new branch and start a pull request. Then click Commit changes or Propose changes.

    Screenshot of the "Propose changes" dialog with the areas mentioned highlighted with an orange outline.

Committing the workflow file to a branch in your repository triggers the push event and runs your workflow.

If you chose to start a pull request, you can continue and create the pull request, but this is not necessary for the purposes of this quickstart because the commit has still been made to a branch and will trigger the new workflow.

Viewing your workflow results

  1. Sur GitHub, accédez à la page principale du référentiel.

  2. Sous le nom de votre dépôt, cliquez sur Actions.

    Capture d’écran des onglets du référentiel « github/docs ». L’onglet « Actions » est mis en surbrillance avec un encadré orange.

  3. In the left sidebar, click the workflow you want to display, in this example "GitHub Actions Demo."

    Screenshot of the "Actions" page. The name of the example workflow, "GitHub Actions Demo", is highlighted by a dark orange outline.

  4. From the list of workflow runs, click the name of the run you want to see, in this example "USERNAME is testing out GitHub Actions."

  5. In the left sidebar of the workflow run page, under Jobs, click the Explore-GitHub-Actions job.

    Screenshot of the "Workflow run" page. In the left sidebar, the "Explore-GitHub-Actions" job is highlighted with a dark orange outline.

  6. The log shows you how each of the steps was processed. Expand any of the steps to view its details.

    Screenshot of steps run by the workflow.

    For example, you can see the list of files in your repository:

    Screenshot of the "List files in the repository" step expanded to show the log output. The output for the step is highlighted with an orange outline.

The example workflow you just added is triggered each time code is pushed to the branch, and shows you how GitHub Actions can work with the contents of your repository. For an in-depth tutorial, see Understanding GitHub Actions.
