Predefined environment variables reference

For an introduction on this subject, read through the getting started with environment variables document.

Some of the predefined environment variables are available only if a minimum version of GitLab Runner is used. Consult the table below to find the version of GitLab Runner that's required.

You can add a command to your .gitlab-ci.yml file to output the values of all variables available for a job.

Kubernetes-specific environment variables are detailed in the Kubernetes deployment variables section.
