GitHub Actions offers features that let you control deployments. You can:
- Trigger workflows with a variety of events.
- Configure environments to set rules before a job can proceed and to limit access to secrets.
- Use concurrency to control the number of deployments running at a time.
For more information about continuous deployment, see "About continuous deployment."
You should be familiar with the syntax for GitHub Actions. 詳しい情� �については、「GitHub Actions を学ぶ」を参照してく� さい。
Triggering your deployment
You can use a variety of events to trigger your deployment workflow. Some of the most common are:
For example, a workflow with the following triggers runs whenever:
- There is a push to the
- A pull request targeting the
mainbranch is opened, synchronized, or reopened.
- Someone manually triggers it.
on: push: branches: - main pull_request: branches: - main workflow_dispatch:

Environments are used to describe a general deployment target like
development. When a GitHub Actions workflow deploys to an environment, the environment is displayed on the main page of the repository. You can use environments to require approval for a job to proceed, restrict which branches can trigger a workflow, or limit access to secrets. For more information about creating environments, see "Using environments for deployment."
並行処理により、同じ並行処理グループを使用する単一のジョブまたはワークフローのみが一度に実行されます。 並行処理では、環境で一度に最大 1 つのデプロイメントが進行中で、1 つのデプロイメントが保留になるようにすることができます。
environment are not connected. The concurrency value can be any string; it does not need to be an environment name. Additionally, if another workflow uses the same environment but does not specify concurrency, that workflow will not be subject to any concurrency rules.
For example, when the following workflow runs, it will be paused with the status
pending if any job or workflow that uses the
production concurrency group is in progress. It will also cancel any job or workflow that uses the
production concurrency group and has the status
pending. This means that there will be a maximum of one running and one pending job or workflow in that uses the
production concurrency group.
name: Deployment concurrency: production on: push: branches: - main jobs: deployment: runs-on: ubuntu-latest environment: production steps: - name: deploy # ...deployment-specific steps
You can also specify concurrency at the job level. This will allow other jobs in the workflow to proceed even if the concurrent job is
name: Deployment on: push: branches: - main jobs: deployment: runs-on: ubuntu-latest environment: production concurrency: production steps: - name: deploy # ...deployment-specific steps
You can also use
cancel-in-progress to cancel any currently running job or workflow in the same concurrency group.
name: Deployment concurrency: group: production cancel-in-progress: true on: push: branches: - main jobs: deployment: runs-on: ubuntu-latest environment: production steps: - name: deploy # ...deployment-specific steps
For guidance on writing deployment-specific steps, see "Finding deployment examples."
When a GitHub Actions workflow deploys to an environment, the environment is displayed on the main page of the repository. For more information about viewing deployments to environments, see "Viewing deployment history."
Monitoring workflow runs
すべてのワークフローの実行は、実行の進行を示すリアルタイ� のグラフを生成します。 You can use this graph to monitor and debug deployments. For more information see, "Using the visualization graph."
You can also view the logs of each workflow run and the history of workflow runs. 詳しい情� �については、「ワークフロー実行の履歴を表示する」を参照してく� さい。
Tracking deployments through apps
You can also build an app that uses deployment and deployment status webhooks to track deployments. When a workflow job that references an environment runs, it creates a deployment object with the
environment property set to the name of your environment. As the workflow progresses, it also creates deployment status objects with the
environment property set to the name of your environment, the
environment_url property set to the URL for environment (if specified in the workflow), and the
state property set to the status of the job. For more information, see "Apps" and "Webhook events and payloads."
You can run your deployment workflow on GitHub-hosted runners or on self-hosted runners. Traffic from GitHub-hosted runners can come from a wide range of network addresses. If you are deploying to an internal environment and your company restricts external traffic into private networks, GitHub Actions workflows running on GitHub-hosted runners may not be able to communicate with your internal services or resources. To overcome this, you can host your own runners. For more information, see "About self-hosted runners" and "About GitHub-hosted runners."
Displaying a status badge
You can use a status badge to display the status of your deployment workflow. ステータスバッジは、ワークフローが現在失敗しているかパスしているかを示します。 ステータスバッジを追� する一般的な� �所は、リポジトリの
README.mdファイル中ですが、任意の好きなWebページに追� できます。 デフォルトでは、バッジはデフォルトブランチのステータスを示します。 特定のブランチやイベントに対するワークフローの実行のステータスを、URL中の
For more information, see "Adding a workflow status badge."
Finding deployment examples
This article demonstrated features of GitHub Actions that you can add to your deployment workflows.
GitHub Enterprise Server offers deployment starter workflows for several popular services, such as Azure Web App. To learn how to get started using a starter workflow, see "Using starter workflows" or browse the full list of deployment starter workflows. You can also check out our more detailed guides for specific deployment workflows, such as "Deploying to Azure App Service."
Many service providers also offer actions on GitHub Marketplace for deploying to their service. For the full list, see GitHub Marketplace.
