Merging multiple tags from hidden jobs

How to Use GitLab
, , ,
1

Hi, I am having trouble getting !reference to work for extending tags across the same file and multiple files (via includes). Can someone please help me? TIA! :hugs:

Problem to solve

Describe your question in as much detail as possible:
What I want to do:

  • The tags should span multiple jobs
  • Have multiple tags that don’t get overwritten
  • Allow for a variable in the tags.

Error: jobs:tester:tags config should be an array of strings
OR, if I am able to run it (using extends) all the tags will not appear.

Steps to reproduce

Recreate a similar issue in a single gitlab-ci.yml for gitlab v15.11:

variables:
  PRD: "prd123"

stages:
  - build

.general_k8srunner_tags:
  - 'bootstrapped_runner'
  - 'gitlab-runner'
  - 'kubernetes'
  - '$PRD'

.k8_non_prod_us_eastern_1_tags:
  - nonprod.us-eastern-1

tester:
  stage: build
  script:
    - echo hello
  tags: 
    - !reference [.general_k8srunner_tags]
    - !reference [.k8_non_prod_us_eastern_1_tags]
  • Tried to change how tags are called in the tester job.
  • I tried specifying the reference object is a tag and made the tags in the hidden jobs part of the tag key.
    See below:
variables:
  PRD: "prd123"

stages:
  - build

.general_k8srunner_tags:
   tags:
     - 'bootstrapped_runner'
     - 'gitlab-runner'
     - 'kubernetes'
     - '$PRD'

.k8_non_prod_us_eastern_1_tags:
   tags:
     - nonprod.us-eastern-1

tester:
  stage: build
  script:
    - echo hello
  tags: 
    - !reference [.general_k8srunner_tags, tags]
    - !reference [.k8_non_prod_us_eastern_1_tags, tags]
  • Tried with a reference to a single hidden job tag (that works), and tried importing with extends (required to add a script to make it work, but if that script is over-written the tags are also removed). See below:
variables:
  PRD: "prd123"

stages:
  - build

.general_k8srunner_tags:
   script:
     - echo "hello world"
   tags:
     - 'bootstrapped_runner'
     - 'gitlab-runner'
     - 'kubernetes'
     - '$PRD'

.k8_non_prod_us_eastern_1_tags:
  - nonprod.us-east-1

tester:
  stage: build
  extends: [.general_k8srunner_tags]
  script:
    - echo "goodbye world"
  tags: !reference [.k8_non_prod_us_eastern_1_tags]

Configuration

we are using 15.11, I am not sure if this is self-managed or not and any of the specific configuration.
