How to Monitor kube-controller-manager

When it comes to creating new Pods from a ReplicationController or ReplicaSet, ServiceAccounts for namespaces, or even new EndPoints for a Service, kube-controller-manager is the one responsible for carrying out these tasks. Monitoring the Kubernetes controller manager is fundamental to ensure the proper operation of your Kubernetes cluster. If you are in your cloud-native journey, running your workloads on top of Kubernetes, don’t miss the kube-controller-manager observability.

Exploring the New Container Checkpointing Feature

Kubernetes is a continuously evolving technology strongly supported by the open source community. In the last What’s new in Kubernetes 1.25, we mentioned the latest features that have been integrated. Among these, one may have great potential in future containerized environments because it can provide interesting forensics capabilities and container checkpointing.

Kubernetes Services: ClusterIP, Nodeport and LoadBalancer

Pods are ephemeral. And they are meant to be. They can be seamlessly destroyed and replaced if using a Deployment. Or they can be scaled at some point when using Horizontal Pod Autoscaling (HPA). This means we can’t rely on the Pod IP address to connect with applications running in our containers internally or externally, as the Pod might not be there in the future.

A day in the life of a Customer Support Detective

I open my laptop and look over my cases while I slurp down my first cup of coffee. Most of my backlog is waiting on customer updates, or bug fixes. Two of my cases have been marked for closure. Not a bad start for a Monday! A pod CrashLoopBackoff issue was resolved by bumping up memory requests, and the missing metrics issue was solved after applying some Prometheus annotations to the customer’s nginx pods. I notate and close both cases. No sooner do I hear the beep of the badge scanner.

Understanding Kubernetes Limits and Requests

When working with containers in Kubernetes, it’s important to know what are the resources involved and how they are needed. Some processes will require more CPU or memory than others. Some are critical and should never be starved. Kubernetes defines Limits as the maximum amount of a resource to be used by a container. Requests, on the other hand, are the minimum guaranteed amount of a resource that is reserved for a container.

How to Monitor Kubernetes API Server

Content Learning how to monitor the Kubernetes API server is crucial when running cloud-native applications in Kubernetes environments. The Kubernetes API server can be considered as the front end of the Kubernetes control plane. Any interaction or request from users or internal Kubernetes components with the control plane go through this component. Ensuring you monitor the Kubernetes API server properly is of vital importance to ensure your Kubernetes cluster works as expected.
