Add docs for GITLAB_ENV variable
What does this MR do and why?
While reviewing https://gitlab.com/gitlab-org/security-products/oxeye/product/lightz/-/merge_requests/180+s, I noticed the use of the $GITLAB_ENV
variable, as discussed here, but couldn't find any documentation for it. This lead to some confusion regarding the capabilities of this variable as discussed here.
This MR adds documentation for the $GITLAB_ENV
variable, in order to reduce confusion. Support for the $GITLAB_ENV
variable was originally introduced by Allow passing of env vars between job stages/steps (gitlab-runner!3708 - merged) • Arran Walker • 16.4,
