How to check either of variable exist in the gitlab rules?

Question

I have a gitlab rule condition like below.

'$ACTION && $REGION && $ROLE_ARN && $PACKAGEURL && $ACTION == "new" && $CLOUD_PLATFORM == "aws" && $ROLE_ARN != "" && $PACKAGEURL != "" && $REGION != ""'

Want to modify it a bit so that, it should check either the existence of PACKAGEURL or BUILDRPMREQUIRED above.

Tried keeping as below but getting run even if the PACKAGEURL or BUILDRPMREQUIRED not provided.

'$ACTION && $REGION && $ROLE_ARN && ($PACKAGEURL || $BUILDRPMREQUIRED) && $ACTION == "new" && $CLOUD_PLATFORM == "aws" && $ROLE_ARN != "" && ($PACKAGEURL != "" || $BUILDRPMREQUIRED != "") && $REGION != ""'

I kept in rule as below.

.ifawsfulldeploy:
  rules:
    - if: '$ADMIN_SERVER_IP && $ADMIN_SERVER_IP != ""'
      when: never
    - if: '$ACTION && $REGION && $ROLE_ARN && ($PACKAGE_URL || $BUILDRPMREQUIRED) && $ACTION == "new" && $CLOUD_PLATFORM == "aws" && $ROLE_ARN != "" && ($PACKAGE_URL != "" || $BUILDRPMREQUIRED != "") && $REGION != ""'
      when: always

Other rules should be there, with only variables I am getting syntax error.

.ifawsfulldeploy:
  rules:
    - if: '$ADMIN_SERVER_IP && $ADMIN_SERVER_IP != ""'
      when: never
    - if: '$ACTION && $REGION && $ROLE_ARN && ( $PACKAGE_URL || $BUILDRPMREQUIRED ) && $ACTION == "new" && $CLOUD_PLATFORM == "aws" && $ROLE_ARN != "" && ( $PACKAGE_URL != "" || $BUILDRPMREQUIRED != "" ) && $REGION != ""'
      when: always

And in my job.

  only:
    variables:
      - $PACKAGE_URL
      - $BUILDRPMREQUIRED
  extends:
    - .ifawsfulldeploy

Answer 2

Have you tried using a rule just for the variables? Like this example from the Gitlab docs:

job1:
  script:
    - echo This rule uses parentheses.
  only:
    variables:
      - ($CI_COMMIT_BRANCH == "main" || $CI_COMMIT_BRANCH == "develop") && $MY_VARIABLE

it seems we can keep only one variable – Steel

can you check the content I added at the end of post now – Steel

What about if you add them like: only: variables: - ($PACKAGE_URL || $BUILDRPMREQUIRED) And remove them from the rule above? (Sorry about the formatting, can't figure out how to format the code properly). – Anaptyxis

Also, you have a mistake, extends: shouldn't point to the same job name, it's circular reference. @Steel – Anaptyxis

sorry for confusion both are at different places, edited the post. – Steel

And still doesn't work – Steel

Can you please share the whole file? Not just the rules? What else do you have in the job that extends the rule? In the original I mean, before trying with the variables. – Anaptyxis

nothing else, only these rules extends – Steel

You can't have jobs without a script element (or before_script/after_script), unless it's a trigger job, so maybe that's why you were getting the syntax errors. – Anaptyxis

Answer 3

You can check variable is not null or check for at least one character in the variable

  rules:
    - if: ( $MY_VARIABLE != null || $MY_VARIABLE =~ /^./ )
