Long, detailed post mortem on a reddit failed k8s upgrade
When the Gatekeeper validatingwebhook came up, I was really worried that'd be the issue! Regardless I'd recommend anyone who cares about their cluster not collapsing to change the gatekeeper webhook to only intercept resources you care about: https://github.com/open-policy-agent/gatekeeper/pull/1806
- Is OPA Gatekeeper the best solution for writing policies for k8s clusters?

Implement DevSecOps to Secure your CI/CD pipeline
Kyverno adds an extra layer of security where only the allowed type of manifest is deployed onto kubernetes, otherwise, it will reject or we can set validationFailureAction to audit which only logs the policy violation message for reporting. Kubewarden and Gatekeeper are alternative tools available to enforce policies on Kubernetes CRD.

Gatekeeper with Istio
Now, we have the hardest part resolved and let's turn our attention to the OPA Gatekeeper. Gatekeeper uses the OPA Constraint Framework to describe and enforce policy. Right now there are mainly 3 parts we should pay attention:

10 Essentials For Kubernetes Multi-Tenancy
They enable you to establish the policies and regulations that govern cluster deployments and applications. Using predefined policies, policy engines can dynamically modify or create configurations. Policy engines such as Gatekeeper and Kyverno can be leveraged to meet legal and compliance requirements while maintaining operational flexibility and development speed.

Kubernetes for Startups: Practical Considerations for Your App
Setup policy around what resource requirements can be requested by an app per environment. OPA and gatekeeper or kyverno can help. Setup access control for who can create or modify apps.

Kubernetes policy management: I - Introduction
OPA Gatekeeper is an open source, general purpose policy engine. OPA decouples policy decisions from other responsibilities of an application, like those commonly referred to as business logic. OPA works equally well making decisions for Kubernetes, Microservices, functional application authorization and more, thanks to its single unified policy language.

Stop 'k rollout restart deploy' from restarting everything?
Anyway, I havenāt checked for sure as Iām 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

Did I miss something here, regarding network policies and helm templates? (Slightly ranty)
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.

kubernetes provider resources v1 vs non-v1 is it just me or is this dumb?
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 Policy As Code Using CDK8S
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.
What are some alternatives?
falco - Cloud Native Runtime Security
cloud-custodian - Rules engine for cloud security, cost optimization, and governance, DSL in yaml for policies to query, filter, and take actions on resources
Kubewarden - Kubewarden is a policy engine for Kubernetes. It helps with keeping your Kubernetes clusters secure and compliant. Kubewarden policies can be written using regular programming languages or Domain Specific Languages (DSL) sugh as Rego. Policies are compiled into WebAssembly modules that are then distributed using traditional container registries.
k-rail - Kubernetes security tool for policy enforcement
OPA (Open Policy Agent) - Open Policy Agent (OPA) is an open source, general-purpose policy engine.
connaisseur - An admission controller that integrates Container Image Signature Verification into a Kubernetes cluster
opa-envoy-plugin - A plugin to enforce OPA policies with Envoy
checkov - Prevent cloud misconfigurations and find vulnerabilities during build-time in infrastructure as code, container images and open source packages with Checkov by Bridgecrew.
