policies VS Kyverno

Recommend Kyverno, it can do what your asking + more, see link for example adding a networkpolicy https://github.com/kyverno/policies/blob/main/best-practices/add_network_policy/add_network_policy.yaml

Make sure you've cloned the fork of kyverno/kyverno and kyverno/policies in the same directory. Your workspace should be looking something like this:

My mentorship period was from 1st March 2022 to 31st May 2022. During this period I have to work with Kyverno policies where I have to write test cases for it using Kyverno CLI.More specifically I have to write test cases along with other required manifests for validate and mutate policies and check them using kyverno applyand kyverno test CLI commands.

During internship, I had to work on feature enhancement and it was To extend the test command to support or handle mutate Policy and also To cover all sample policies. The same reaction I also had earlier after reading this project headline. Didn't understand anything. So, the recommendation to newbie contributors that the best way to understand any project is to read the documentation first and then install that project in your local machine and try to use it, play with it until and unless you get the feel about that project.

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.
