Nova: A Go repository from jedi132000

Find outdated or deprecated Helm charts running in your cluster.

Nova scans your cluster for installed Helm charts, then cross-checks them against all known Helm repositories. If it finds an updated version of the chart you're using, or notices your current version is deprecated, it will let you know.
