The variables that are defined +in the project settings are sent along with the build script to the runner. +The secure variables are stored out of the repository. Never store secrets in +your project's `.gitlab-ci.yml`. It is also important that the secret's value +is hidden in the job log. + +You access added variable by prefixing it's name with `$` (on non-Windows runners) +or `%` (for Windows Batch runners): + +1. `$VARIABLE` - use it for non-Windows runners +1. `%VARIABLE%` - use it for Windows Batch runners + +Read more about the [CI/CD variables](../../variables/index.md). |
