nova (Nudgebee fork)

Find outdated or deprecated Helm charts running in your cluster.

This is a Nudgebee-maintained fork of FairwindsOps/nova. Nudgebee is not affiliated with, endorsed by, or sponsored by FairwindsOps, Inc. The names "Nova" and "FairwindsOps" and the original Nova logo are trademarks of FairwindsOps, Inc.; this fork does not use the upstream logo in any released build (see NOTICE for details). The original work is © FairwindsOps, Inc. and is licensed under the Apache License 2.0 — see LICENSE and NOTICE.

nova scans your cluster for installed Helm charts, then cross-checks them against known Helm repositories. If it finds an updated version of a chart you're using, or notices that your current version is deprecated, it will let you know. It can also scan your cluster for out-of-date container images.

For the original feature documentation see the upstream docs.

What's different in this fork

Area	Change
Output	ReleaseOutput now includes the source Helm RepositoryUrl for matched releases.
Output	VersionInfo now includes a Date field — FirstDeployed for the installed version, Created for the latest version.
Discovery	New pkg/helm/helm_repo_exporter.go calls ArtifactHub's /helm-exporter API and (with FindHelmRepoMatch in pkg/helm/findscore.go) attaches the source repo URL to each release. Optional file cache via ARTIFACT_HELM_REPO_HUB_CACHE_FILE.
CLI	Removed the upstream "Want more? Automate Nova for free with Fairwinds Insights!" message that was printed after every command.
Build	Multi-stage Dockerfile that builds nova from source instead of copying a pre-built binary.
CI	GitHub Actions workflows that build a multi-arch image and push to Nudgebee's container registry.
Misc	Removed the upstream CircleCI pipeline, goreleaser config, and VuePress docs site (all of which were tied to FairwindsOps-private infra).
Deps	Many dependency upgrades. See CHANGELOG.md and git log for the full history.

A more detailed list lives in CHANGELOG.md. Significant modifications are also summarized in NOTICE.
