 Argo CD UI extension that displays vulnerability report data from [Trivy](https://aquasecurity.github.io/trivy), an open source security scanner.
 
 `Trivy` creates a vulnerability report Kubernetes resource with the results of a security scan. The UI extension then parses the report data and displays it as a grid and dashboard viewable in Pod resources within the Argo CD UI.

 ## Install UI extension
 
 The UI extension needs to be installed by mounting the React component in Argo CD API server. This process can be automated by using the argocd-extension-installer. This installation method will run an init container that will download, extract and place the file in the correct location.
