Gitlab scheduled pipeline also run another job not on schedule - gitlab

Question

I'm new to this Gitlab CI/CD features, and I encountered the following issues.
I have these 2 jobs in my gitlab-ci.yml, the automation test and my deployment job.
automation_test_scheduled:
stage: test
script:
- yarn test:cypress
only:
- schedules
deploy_to_staging:
stage: deploy-staging
environment: staging
only:
- staging
I want to run my automation test automatically on a daily basis and I have created a new pipeline schedule against my staging branch.
however, when the scheduler is triggered, it also runs my deployment job, which is not needed because I only want my automation test to run in the scheduled pipeline.
Does this happen because my deploy_to_staging job has only: - staging rules? if so, how can I set my scheduled pipeline to only run the automation test without triggering another job?

Answer 1

If you wanted to do this with only/except, it would probably be sufficient to add
except:
- schedules
to your deployment job.
Though as
Though notably, the rules based system is preferred at this point.
This also allows for more expressive and detailed decisions when it comes to running jobs.
The simplest way to set the rules for the two jobs would be:
automation_test_scheduled:
stage: test
script:
- yarn test:cypress
rules:
- if: $CI_PIPELINE_SOURCE == "schedule"
deploy_to_staging:
stage: deploy-staging
environment: staging
rules:
- if: $CI_PIPELINE_SOURCE == "schedule"
when: never
- if: $CI_COMMIT_REF_SLUG == "staging"
And that might be all you need.
Though when it comes to rules, a particularly convenient way of handling them is defining some common rules for the configuration, and reusing these through yaml anchors. The following are some reusable definitions for your case:
.definitions:
rules:
- &if-scheduled
if: $CI_PIPELINE_SOURCE == "schedule"
- &not-scheduled
if: $CI_PIPELINE_SOURCE == "schedule"
when: never
- &if-staging
if: $CI_COMMIT_REF_SLUG == "staging"
And after that you could use them in your jobs like this:
automation_test_scheduled:
stage: test
script:
- yarn test:cypress
rules:
- *if-scheduled
deploy_to_staging:
stage: deploy-staging
environment: staging
rules:
- *not-scheduled
- *if-staging
This way of handling the rules makes it a bit easier to have a overview, and to reuse rules, which in large configurations definitely makes sense

Answer 2

You should use rules instead of only as the latter is not in active development any more.
With that in mind you can change to the following rules clause using the predefined variables CI_COMMIT_REF_SLUG and CI_PIPELINE_SOURCE. The automation_test_scheduled is only run on the branch staging if triggered by a schedule and the deploy_to_staging job is run on any change on the staging branch.
automation_test_scheduled:
stage: test
script:
- yarn test:cypress
rules:
- if: '$CI_COMMIT_REF_SLUG == "staging" && $CI_PIPELINE_SOURCE == "schedule"'
deploy_to_staging:
stage: deploy-staging
environment: staging
rules:
- if: '$CI_COMMIT_REF_SLUG == "staging"'
