unknown field "capabilities" in io.k8s.api.core.v1.PodSecurityContext (running tshark in a container/k8s pod)
so probably the right way is to use some tool like that (ksniff) or setup a sidecar container. But I am still curious to why I get the above error.

Running tcpdump on eks worker nodes
I've used https://github.com/eldadru/ksniff with success. Recently on this sub Kubeshark was also mentioned.

How can I see mTLS traffic in a K8s cluster that also uses Istio?
I've found ksniff useful for monitoring Kubernetes traffic with wireshark: https://github.com/eldadru/ksniff

Making Kubernetes Operations Easy with kubectl Plugins
ksniff - known as sniff is a tool for debugging and capturing networking data. It's able to attach to a pod and using tcpdump to forward networking data to your local Wireshark. This tool also works pretty well with tshark - the command-line version of Wireshark.

New IBM LinuxONE 4 Express – Rack-mounted pre-configured Linux mainframe
Agreed. The tooling around upgrades is painfully atrocious, and stuff like kubepug [1] should be part of the Kubernetes core.

Not strictly related to security, but I find kubepug awesome when planning upgrades, especially if you need to jump across 2 or 3 major versions.

Making Kubernetes Operations Easy with kubectl Plugins
kube-pug - is a plugin known as deprecations in krew. Every cluster needs to be upgraded sooner or later and at some point you will run into API deprecations and/or removals. Finding what's being deprecated can be long and error-prone process and this plugin tries to simplify that. All you need to do is run kubectl deprecations --k8s-version=v1.XX.X and you will get list of all the instances of API objects in cluster that will be deprecated or removed in the specified version.
