Kubernetes and the Reconciler Pattern: Maintaining Order in the Chaos
In the ever-evolving world of cloud-native deployments, maintaining a stable and predictable environment can be a challenge. Kubernetes, the popular container orchestration platform, tackles this challenge through various mechanisms, with the reconciler pattern being a cornerstone of its functionality. What is the Reconciler Pattern? The reconciler pattern is a design approach that ensures a system’s
Kubernetes in Production: Should you run your own worker nodes?
Kubernetes offers a powerful platform for containerized applications, but a crucial decision arises: manage your worker nodes yourself or leverage a managed service. Both options have their merits, and the optimal choice depends on your specific needs and resources. Understanding Worker Nodes: The Workhorses of Kubernetes Worker nodes are the grunt workers in your Kubernetes
Kubernetes in Production: Managed Control Plane – Worth Considering for Kubernetes
Kubernetes offers immense power for container orchestration, but managing the control plane can be a complex and time-consuming task. Here’s why a managed control plane should be a strong consideration, regardless of your specific Kubernetes deployment. The Control Plane: The Brains of the Operation The Kubernetes control plane acts as the central nervous system of
Kubernetes in Production: How NodeLocal DNS Boosts Production Performance
Running Kubernetes in production is fantastic, but sluggish DNS resolution can bring your applications to a crawl. Here’s where NodeLocal DNS swoops in, a secret weapon for keeping your containerized world running smoothly and scaling like a champ. The DNS Dilemma: Traffic Jams in Your Cluster Normally, Kubernetes relies on a central service called kube-dns
Kubectl get pods: Birds Eye View
Kubernetes has become the most popular choice to deploy and manage micro-services. If you are new to Kubernetes or you’ve recently started using it, you’d be aware of the advantages it provides.

Basics on Kubernetes: Basic debugging with kubectl
In our previous article series on Basics on Kubernetes which is still going, we talked about different components like control plane, pods, etcd, kube-proxy, deployments, etc. You can read the article series on Learnsteps. In this article, we are going to see how we can do basic debugging in Kubernetes. Before starting I am assuming
Kubernetes Upgrade Failure Story: How a CNI config caused havoc in our Redis Infrastructure.
In one of my organizations, most of our Redis infrastructure runs on Kubernetes. if you know about the Redis cluster, you can connect to shards using the IP of the machines. Since we are running Redis in statefulsets, we have exposed the IPs of the pods inside our infrastructure. Kubernetes cluster is EKS and the
