Creating the Kubernetes objects extension

Kubernetes (K8s) is a very demanding topic when working with microservices or containers. We have seen in the previous chapters, how you can declaratively deploy K8s objects such as Deployments and Services inside K8s clusters, for which we create a YAML file containing the K8s object-specific information. The YAML file has a fixed-tab delimited format and a single space or invalid indentation can cause the deployment to fail. Let's see how this happens.

Generating the code snippet extension project for K8s objects

In this section, we will create an extension that will help us to scaffold the Deployment and Service templates for K8s objects. Let's begin:

1. To start with, we will first create a new folder named K8sext. Then run the following command to start building the extension:

   yo code 

2. From the list of extensions, choose New Code Snippets shown as follows:
