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 Runner required.

Note: Starting with GitLab 9.0, we have deprecated some variables. Read the 9.0 Renaming section to find out their replacements. You are strongly advised to use the new variables as we will remove the old ones in future GitLab releases.

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.
