I'd like to deploy additional services (e.g. a certain kind of database) with my (review) application when using GitLab Auto DevOps. Customizing Auto DevOps/Custom Helm chart suggests to create a ./chart directory and put the full chart there.
Does that mean I have to copy the complete default chart to my repository, only to add a ./chart/requirements.yaml file? Is there a possibility to somehow "merge" the charts? I don't need to fully replace the default chart with a custom chart, I only need to add requirements (and override a few settings in ./chart/values.yaml; which can already be done with Customize Helm chart values).
What's the canonical way to add a requirement to the default chart?
- Copy the complete default chart and adapt? (feels like overkill and needs to be kept in sync manually)
- Override the deployment CI pipeline job to download the default chart and merge it with the custom requirements?
- Find a way similar to customizing Helm chart values – does it exist?
- Adding another CI pipeline job to deploy the requirement separately?
