Step by Step Guide on How to Deploy a Crypto Server Application in Minikube (Kubernetes)
In this article, we'll explain how to set it up locally Minicopy (Kubernetes) on our devices and deploy an instance of a Spring boot Application called Encryption server. Unlike regular applications that use HTTP, our server will use our own encryption RSocket. Additionally, we'll show you how to deploy an instance of MongoDB The database in Minikube, which the Book API relies on for storage.
You can find the full code and implementation of the Book API in the article linked below. Feel free to follow the steps outlined in the article and get started.
So let's get started!
To follow along with this guide, next Java 17+ And DockerPlease make sure you have it Minicopy, Copycatl And VirtualBox installed on your device.
When we use Kubernetes to manage our applications, it is responsible for maintaining the health of the pods. For example, it ensures that our applications start accepting requests only when they are ready. If the pod's main process crashes, the pod will be restarted.
To handle these tasks, Kubernetes has two probes: liveness and readiness.
- The readiness probe is used to verify that the application is ready to receive requests. In simple terms, a capsule is ready when all its containers are ready;
- The vitality probe is used to check if the capsule is still in operation. This helps it determine when to restart the container.
Let's go ahead and add the engine dependency and enable the liveness and readiness probes.
Add engine dependency
In the pom.xml file, let's include the operator dependency by adding the following code (shown in wide):
