Helm-trivy

This is a small helm plugin that performs vulnerability scans on container images used by charts. It was inspired by Snyk.io's helm-snyk plugin. It uses aquasec's trivy instead of Snyk.io for vulnerability scanning. To be fair, I found in my testing that Snyk had better results, but trivy isn't far (and it's free).

Installation

Just like any helm plugin, use the helm plugin subcommand:

helm plugin install  https://github.com/ObjectifLibre/helm-trivy

Currently avalaible for linux and mac platforms.
