With the introduction of Elastic Kubernetes service at re: Invent last year, AWS finally threw their hat in the ever booming space of managed Kubernetes services. In this blog post, we will learn the basic concepts of EKS, launch an EKS cluster and also deploy a multi-tier application on it.
Custom resources definition (CRD) is a powerful feature introduced in Kubernetes 1.7 which enables users to add their own/custom objects to the Kubernetes cluster and use it like any other native Kubernetes objects. In this blog post, we will see how we can add a custom resource to a Kubernetes cluster using the command line as well as using the Golang client library thus also learning how to programmatically interact with a Kubernetes cluster.
As per this article, Custom Resource Definitions are part of a wider effort to refine and enhance Kubernetes as an extensible application platform, factoring everything but the bare essentials out of “core” Kubernetes in favour of modular and maintainable extensibility mechanisms.
In this blog we understand how one can go about writing their own CRDs with a hand-on demonstration.
Jenkins X is a project which rethinks how developers should interact with CI/CD in the cloud with a focus on making development teams productive through automation, tooling and DevOps best practices.
In this blog, we explore Jenkins X, understand how it differs from Jenkins and how to go about building and deploying our first application using it.
Kubernetes allows deployment and management container-based applications at scale. One of the main advantages of Kubernetes is how it brings greater reliability and stability to the container-based distributed application, through the use of dynamic scheduling of containers. But, how do you make sure Kubernetes itself stays up when a component or its master node goes down?
In this blog we look at the steps to ensure that your kubernetes cluster is always highly available and fault tolerant.
In the age of continuous delivery and agility where the software is being deployed 10s of times per day and sometimes per hour as well using container orchestration platforms, a seamless upgrade mechanism becomes a critical aspect of any technology adoption. In this blog we explore the various upgrade strategies available for Statefulsets in Kubernetes with Cassandra as the database.
This blog talks about Azure's Kubernetes as a Service offering - AKS. I came across various issues while setting up AKS and its container registry so wanted to share some gotchas.
Finally, this blog provides the steps to setup continuous deployment pipeline with Azure Kubernetes Service, Azure Container Registry & Jenkins.
