kubeclarity VS Kyverno

In the following steps, we use a local Kubernetes cluster (such as kind) to test the image. With the cluster up and running, let's install some tooling to help us with image scanning. In this case, we're using KubeClarity. Follow the installation instructions in the README to install it into your development cluster.

Introducing KubeClarity. KubeClarity is an open-source project to help you ship more secure software. While KubeClarity covers many different use cases, let's focus on image scanning for now.

KubeClarity runs on any Kubernetes cluster and provides a UI and CLI for analyzing images and generating SBOMs. By default, KubeClarity doesn’t have its own SBOM generator or vulnerability scanner, but instead supports third-party tools that you can enable in any combination, making it great for adding additional interfaces for existing toolchains.

the only thing I can think of is something like https://github.com/openclarity/kubeclarity but that's a little OTT for me.

I stumbled across https://github.com/cisco-open/kubei recently, it looks the goods but I have not had time to implement yet

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.
