Authors: Adrian Reber (Red Hat) In my previous
article, Forensic container checkpointing in Kubernetes,
I introduced checkpointing in Kubernetes and how it has to be setup
and how it can be used.The name of the feature is Forensic
container checkpointing, but I did not go into any details how to
do the actual analysis of the checkpoint created by Kubernetes.In
this article I want to provide details how the checkpoint can be
analyzed. Checkpointing is still an alpha feature in Kubernetes and
this article wants to provide a preview how

Have you ever wondered how to set up a cluster of thousands of nodes just in seconds, how to simulate real nodes with a low resource footprint, and how to test your Kubernetes controller at scale without spending much on infrastructure?
If you answered "yes" to any of these questions, then you might be interested in KWOK, a toolkit that enables you to create a cluster of thousands of nodes in seconds.
What is KWOK?

Kubernetes Katacoda, the popular learning platform from
O’Reilly that has been helping people learn all about Java, Docker,
Kubernetes, Python, Go, C++, and more, shut down for public use in June 2022.However,
tutorials specifically for Kubernetes, linked from the Kubernetes
website for our project’s users and contributors, remained
available and active after this change.Unfortunately, this will no

will cease working after March 31st, 2023. The Kubernetes Project

Authors:Mahamed Ali (Rackspace Technology) The
Kubernetes project runs a community-owned image registry called
registry.k8s.io
to host its container images.On the
3rd of April 2023, the old registry k8s.gcr.io
will be
frozen and no further images for Kubernetes and related subprojects
will be pushed to the old registry. This registry
registry.k8s.io
replaced the old one and has been
generally available for several months.We have published a blog post about its benefits to the community

Observability requires the right data at the right time for the
right consumer (human or piece of software) to make the right
decision.In the context of Kubernetes, having best practices for
cluster observability across all Kubernetes components is crucial.
SIG Instrumentation helps to address this issue by providing best
practices and tools that all other SIGs use to instrument
Kubernetes components-like the Api server,
scheduler, kubelet and
kube-controller-manager. In this SIG
