My environment requires the use of the predefined variable CI_PROJECT_NAMESPACE in .gitlab-ci.yml; however, this variable is in all caps, which makes my build job fail. I've tried several ways to convert the value of this variable to all lowercase with no success:

variables:
  CI_PROJECT_NAMESPACE: $CI_PROJECT_NAMESPACE | tr '[:upper:]' '[:lower:]' # doesn't work

build_image:
  stage: build
  image:
    name: #...
    entrypoint: #...
  before_script:
    - export CI_PROJECT_NAMESPACE=$CI_PROJECT_NAMESPACE | tr '[:upper:]' '[:lower:]' # also doesn't work

I have successfully hard-coded this variable for my own use, but I need the script to work for other users as well without requiring them to hard-code it themselves. Thanks in advance for your thoughts!

You had it almost right. You just can't pipe variable itself to tr. You have to use echo in command substitution, which you can pipe to tr.

before_script:
- export CI_PROJECT_NAMESPACE=$(echo "$CI_PROJECT_NAMESPACE" | tr '[:upper:]' '[:lower:]')
