All CI values files used the flat key exporterConfig.gitlab_url while values.yaml and the application config both use the nested key exporterConfig.gitlab.url. Helm's deep merge treated these as separate keys, leaving the default https://gitlab.com permanently in effect regardless of what was specified.

Root cause

# values.yaml (correct — what the app reads)
exporterConfig:
  gitlab:
    url: "https://gitlab.com"

# ci/*-values.yaml (wrong — different key, never overrides the above)
exporterConfig:
  gitlab_url: "https://gitlab.example.com"

Changes

• ci/*.yaml — Replace flat gitlab_url: "..." with the correct nested gitlab:\n url: "..." structure in all five CI values files
• tests/configmap_test.yaml — Update assertion pattern to match url: inside the gitlab: block; add negative assertion that the default gitlab.com URL is absent when a custom URL is set
• .github/workflows/helm-chart.yml
  • Fix lint step --set flag: exporterConfig.gitlab_url → exporterConfig.gitlab.url
  • Add a Validate GitLab URL is set from values step to the template-test job that parses the rendered ConfigMap and fails if the URL is still the hardcoded default

Original prompt

The current issue is that the GitLab URL remains set to gitlab.com even when a custom GitLab URL is specified in the values.yaml file. This could be due to an issue with how the chart processes the values.yaml file, or how the GitLab URL is being overwritten or ignored.

Task:

• Analyze the helm chart to understand how the GitLab URL is being set.
• Check for any placeholders, environment variables, or defaults that override the value set in values.yaml.
• Investigate if there are scripts or deployment files that hardcode gitlab.com, bypassing the provided values.yaml.
• Create validation tests within the GitHub Actions workflow to catch this issue in future updates.
• Confirm that the value set in values.yaml properly configures the GitLab URL.

Deliverables:

• A fix to ensure that the custom GitLab URL from values.yaml is respected when deploying the chart.
• Addition of validation tests to the GitHub Actions workflow to ensure this functionality is checked in pipeline runs.
