vmclarity VS Kyverno

VMClarity works similarly, but within the context of VMs used by cloud services to host containers and clusters. Compared to containers, VMs may be as (or even more) vulnerable to threats and they typically need complex tools for analysis. Following a similar pattern to KubeClarity, VMClarity supports aggregating multiple tools into one UI and CLI.

Anyway, I haven’t checked for sure as I’m away from laptop but it should be possible to use something like Kyverno to block that operation. We had to do similar in the past to hotfix a bug in our CLI tool. I wrote a blog post about it that might give you an idea: https://www.giantswarm.io/blog/restricting-cluster-admin-permissions

Cosign is used for signing containers through a variety of different methods. It has strong integration with other open source tools, such as Kyverno.

Kyverno - Kubernetes Native Policy Management

You could use a policy tool like kyverno or OPA.

Kyverno is present in the management cluster;

You do still have to create a policy for every namespace, but don't have to worry about labeling individual pods. We're starting to move to Helm/kustomize for our namespaces to deploy default things like network policies to each one, and we're also starting to use kyverno more, which I think is a little more purpose built for this type of thing than metacontroller is.

I knew it was unsupported so about 6 months ago I had started an effort to switch to Kyverno, which is far better and actually supported. The version of Kyverno I was using had a v1beta1 AdmissionController. Fortunately that was in a helm chart so easily caught by pluto before my upgrade.

Kyverno Kyverno is a policy engine designed for Kubernetes, Kyverno policies can validate, mutate, and generate Kubernetes resources plus ensure OCI image supply chain security.
