It looks safe to me in the sense that I don’t see any malicious code in here. I don’t think the committee is trying to sneak in security hopes or similar. So all good on from that perspective.
It’s a very simple helm chart which is consideration! Here’s the thing with charts. They’re meant to be an official means of distributing your app’s manifests for k8s. One package with all runtime needs defined. If the chart supports every tweak I need, then it’s great! If it doesn’t, then I need to modify it myself. This usually means forking the project, making edits, and templating from the fork. It’s a lot of overhead for end users. If the maintainer is willing, it’s so much easier to create an issue or submit a PR with the needed changes.
Your project has some stars and forks. People are likely using it. Grats! The helm chart doesn’t like meet everyone’s needs and I would expect this to spur some extra issues and PRs. Is that good or bad? That’s up to you!!
