GitLab scheduled pipeline: Don't notify owner

The owner of a scheduled CI/CD pipeline in GitLab will always be notified if the pipeline fails.

Follow these steps if you don't want this:

1. Create a Project Access Token with api scope and maintainer role
2. Create the scheduled pipeline with that token:

   Copycurl --request POST --header "PRIVATE-TOKEN: ${TOKEN}" \
     --form description="Daily pipeline check" \
     --form ref="main" \
     --form cron="0 10 * * *" \
     --form cron_timezone="UTC" \
     --form active="true" \
     "https://${GITLAB_URL}/api/v4/projects/${PROJECT_ID}/pipeline_schedules"
   

3. Optional: Configure other notifications like Slack or Pipeline status emails with Integrations

Add a CI/CD variable to the scheduled pipeline

Only the owner of a pipeline can add a CI/CD variable with the GUI. The following steps show how a variable can be added with the GitLab API:

1. Find the PIPELINE_ID for the created scheduled pipeline:

Copycurl --header "PRIVATE-TOKEN: ${TOKEN}" \
  "https://${GITLAB_URL}/api/v4/projects/${PROJECT_ID}/pipeline_schedules" \
  | jq
  
[
  {
    "id": 87,
    "description": "Daily pipeline check",
    ...
  }
]

2. Add the variable (key and value) to the pipeline:

Copycurl --request POST --header "PRIVATE-TOKEN: ${TOKEN}" \
--form "key=CI_SCHED_FREQ" \
--form "value=weekly" \
"https://${GITLAB_URL}/api/v4/projects/${PROJECT_ID}/pipeline_schedules/${PIPELINE_ID}/variables"

3. Check the result:

Copycurl --header "PRIVATE-TOKEN: ${TOKEN}" \
"https://${GITLAB_URL}/api/v4/projects/${PROJECT_ID}/pipeline_schedules/${PIPELINE_ID}" \
| jq

{
...
  "variables": [
    {
      "variable_type": "env_var",
      "key": "CI_SCHED_FREQ",
      "value": "weekly",
      "raw": false
    }
  ]
}

4. Use the variable like any other CI/CD variable:

Copy...
  rules:
    - if: $CI_PIPELINE_SOURCE == "schedule" && $CI_SCHED_FREQ == "weekly"
