It is safe to say that the Microservice + Cloud combination is all the rage these days. Microservices are being developed more than ever, in turn resulting in an increase in the number of application deployments. During the past decade, containerization and orchestration tools such as Docker and Kubernetes were developed, making the microservice pattern really easy to adopt. This ...

On the previous blog we created our Kubernetes deployment files for our Ignite application. On this blog we shall deploy our Ignite application on Kubernetes. I will use minikube on this. Let’s build first 1 mvn clean install I shall create a simple docker image, thus a Dockerfile is neeeded.Let’s add a Dockerfile to the root of our project. 1 ...

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. As described on a previous blog we need to have our Kubernetes RBAC policies in place. We ...

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. Let’s create our project using Spring Boot. The Spring Boot application will connect to the Ignite cluster. Let’s add our dependencies. <?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 ...

Previously we saw the Ignite configuration that comes with the Kubernetes installation.The default configuration does not have persistence enabled so we won’t focus on any storage classes provided by the helm chart. The default installation uses a stateful set. You can find more information on a stateful set on the Kubernetes documentation. 01 02 03 04 05 06 07 08 ...

Previously we had a look on the RBAC needed for and ignite cluster in Kubernetes. This blogs focuses on the deployment and the configuration of the cache.

You had a cache service running however all you did was installing a helm chart.In this blog we shall evaluate what is installed and take notes for our futures helm charts. The first step would be to view the helm chart. 1 2 3 > helm list NAME            NAMESPACE   REVISION    UPDATED                                 STATUS      CHART           APP VERSION ignite-cache    default     1           2020-03-07 22:23:49.918924 ...

I’ve recently been working on an app which processes data in an email box. Old school! What’s the best way to test that? We could mock out the mail service and do occasional smoke tests against the real mail server. That approach is fine, but leaves the mail server integration code untested for most builds. Another approach is to black ...

ge Credit: https://github.com/GoogleContainerTools/jib Building containerized applications require a lot of configurations. If you are building a Java application and planning to use Docker, you might need to consider Jib. Jib is an opensource plugin for Maven and Gradle. It uses the build information to build a Docker image without requiring a Dockerfile and Docker daemon. In this article, we will ...
