Environments

About environments

You can configure environments with protection rules and secrets. When a workflow job references an environment, the job won't start until all of the environment's protection rules pass. A job also cannot access secrets that are defined in an environment until all the environment protection rules pass.

Environment protection rules and environment secrets are only available on public repositories. If you convert a repository from public to private, any configured protection rules or environment secrets will be ignored, and you will not be able to configure any environments. If you convert your repository back to public, you will have access to any previously configured protection rules and environment secrets.

Environment protection rules

Environment protection rules require specific conditions to pass before a job referencing the environment can proceed. You can use environment protection rules to require a manual approval or to delay a job.

Required reviewers

Use required reviewers to require a specific person or team to approve workflow jobs that reference the environment. You can list up to six users or teams as reviewers. The reviewers must have at least read access to the repository. Only one of the required reviewers needs to approve the job for it to proceed.

For more information on reviewing jobs that reference an environment with required reviewers, see "Reviewing deployments."

Wait timer

Use a wait timer to delay a job for a specific amount of time after the job is initially triggered. The time (in minutes) must be an integer between 0 and 43,200 (30 days).

Environment secrets

Secrets stored in an environment are only available to workflow jobs that reference the environment. If the environment requires approval, a job cannot access environment secrets until one of the required reviewers approves it. For more information about secrets, see "Encrypted secrets."

Creating an environment

To configure an environment in a user account repository, you must be the repository owner. To configure an environment in an organization repository, you must have admin access.

1. GitHubで、リポジトリのメインページにアクセスしてください。
2. リポジトリ名の下で Settings（設定）をクリックしてください。
   
3. In the left sidebar, click Environments.
4. Click New environment.
5. Enter a name for the environment, then click Configure environment. Environment names are not case sensitive. An environment name may not exceed 255 characters and must be unique within the repository.
6. Configure any environment protection rules or environment secrets.

Running a workflow that references an environment that does not exist will create an environment with the referenced name. The newly created environment will not have any protection rules or secrets configured. Anyone that can edit workflows in the repository can create environments via a workflow file, but only repository admins can configure the environment.

Referencing an environment

Each job in a workflow can reference a single environment. Any protection rules configured for the environment must pass before a job referencing the environment is sent to a runner. When the job is sent to the runner, the job can access the environment's secrets.

For more information on syntax to reference environments in workflows, see "Workflow syntax for GitHub Actions." For more information on reviewing jobs that reference an environment with required reviewers, see "Reviewing deployments."

When a workflow references an environment, the environment will appear in the repository's deployments. For more information about viewing current and previous deployments, see "Viewing deployment history."

Deleting an environment

To configure an environment in a user account repository, you must be the repository owner. To configure an environment in an organization repository, you must have admin access.

Deleting an environment will delete all secrets and protection rules associated with the environment. Any jobs currently waiting because of protection rules from the deleted environment will automatically fail.

1. GitHubで、リポジトリのメインページにアクセスしてください。
2. リポジトリ名の下で Settings（設定）をクリックしてください。
   
3. In the left sidebar, click Environments.
4. Next the the environment that you want to delete, click .
5. Click I understand, delete this environment.
