Update environment name for Linux docker images
What does this MR do?
Update environment name for Linux docker images
Why was this MR needed?
Part of #27963 we
are
scoping
certain environment variables to jobs so they are only available in that
job. For DOCKER_HUB_PASSWORD and DOCKER_HUB_USER we already scoped
it for stable/docker_images/* in
#27963 (comment 601887655)
but this doesn't match the stable/docker_image environment for the
Linux containers.
Update the name to match the wildcard scope.
