Previously we have been successful on creating our first Spring boot Application powered by Apache Ignite. On this blog we shall focus on what is needed to be done on the Kubernetes side in order to be able to spin up our application.

On a previous series of blogs we spun up an Ignite cluster on a Kubernetes cluster.In this tutorial we shall use the Ignite cluster created previously on with a Spring Boot Application.

Of course, when it comes to certificates, it’s fairly straight forward to rotate a certificate ...

Just a few months ago, I had the chance to get my hands dirty with Kubernetes for the very first time. Up until that point, all I knew about it is that it is something that ensures containerized applications run smoothly in a cluster, nothing else. After finishing my “hello world” and trying out some examples, I have decided to ...
