YAKC - Yet Another Kubernetes Client
Introduction This example shows how you can access the Kubernetes cluster’s REST API from inside a Pod using YAKC (Yet Another Kubernetes Client), Eclipse JKube and Spring Boot. The first part of the tutorial shows how to create a very simple Spring Boot application with the required YAKC Kubernetes Client dependency (see introductory post for YAKC). The second part describes how to quickly deploy the application into a Kubernetes cluster and how to perform requests to the Pod’s REST endpoints to retrieve information from the cluster. Example application The first step will be to create an example Spring Boot Maven […]

However, accessing low-level REST API operations or specific API versions is hard because some of these decisions are taken for you (for now). This is the main reason that drove me to implement Yet Another Kubernetes Client (YAKC) as a side project during these Easter holidays. […]
