Environments

Railway environments give you an isolated instance of all services in a project.

How it Works

All projects in Railway are created with a production environment by default. Once a project has been created, new environments can be created and configured to complement any development workflow.

Types of Environments

Persistent Environments

Persistent environments are intended to persist but remain isolated from production with regard to their configuration.

For example, it is a common pattern to maintain a staging environment that is configured to auto-deploy from a staging branch and with variables relevant to staging.

PR Environments

PR Environments are temporary. They are created when a Pull Request is opened on a branch and are deleted as soon as the PR is merged or closed.

Environment Isolation

All changes made to a service are scoped to a single environment. This means that you can make changes to a service in an environment without affecting other environments.

Use Cases

Environments are generally used for isolating changes from the production environment, to iterate and test before pushing to production.

Have development environments for each team member that are identical to the production environment
Have separate staging and production environments that auto-deploy when changes are made to different branches in a code repository.
