Railway environments give you an isolated instance of all plugins in a project. You can use them to

  • Have development environments for each team member that are identical to the production environment
  • Have separate staging and production environments

Each environment has the same plugins. When a new plugin is added to the project, an instance of that plugin is created for each environment.

Deploys are also scoped to a specific Railway environment. When you create a GitHub Trigger you can specify which environment to use. When you deploy with up, the current environment will be used.

Create an Environment

You can create an environment under Settings > Environments. When you create an environment, Railway provisions another copy of existing plugins from the production environment.

Environment Deploys

Running railway up with an environment selected from the CLI will create a deploy using the variables from the Environment.

Ephemeral Environments

If you enable Pull Request Deploys, a temporary environment is spun up to support the Pull Request deploy. These environments are deleted as soon as these PRs are merged or closed.
