This blog post demonstrates how you can use the Operator Lifecycle Manager to deploy a Kubernetes Operator to your cluster. Then, you will use the Operator to spin up an Elastic Cloud on Kubernetes (ECK) cluster. An operator is a software extension that uses custom resources (extension of the Kubernetes...

Modern project development often requires developers to understand not one or two core technologies, but a whole range of them. It can involve different programming languages, structures, and databases or cloud operating systems. However, one of the main challenges is scaling and configuring the interactions and dependencies of these components...

To start with, I would like to explain what does self-healing means in terms of Kubernetes. Self-healing is a fantastic feature of Kubernetes to recover from service or node failure automatically. In the following article, we will consider the benefit of using replication for your micro-services and how the Kubernetes...

In an ideal world, Docker containers should be ephemeral without any reliance on external storage. In the microservice world, this is achievable when services are connecting to external databases, queues, and other services. Sometimes though, we need persistent storage, when we're running services such as Jenkins, Prometheus, or Postgres. Fortunately,...
