Nested variables in build:resource_group are not expanded.
Summary
Nested variables used in the YAML build:resource_group key are not expanded. Expansion of nested variables was recently implemented for environment:url. This page in the Gitlab docs states variable expansion for build:resource_group should work similar to that of environment:url, implying it should work, but it does not.
Steps to reproduce
Take the following .gitlab-ci.yml:
variables:
PARENT_VARIABLE: "parent"
NESTED_VARIABLE: ${PARENT_VARIABLE}_nested
build:
script:
- "echo 'hello'"
- "sleep 10"
resource_group: ${NESTED_VARIABLE}Run several instances of this pipeline at the same time. Subsequent pipeline pages will show "This job is waiting for resource: ${PARENT_VARIABLE}_nested", rather than "parent_nested".
