In that blog post we will focus on: Creating a bundle for the example operator. That bundle will be used to install the example frontend operator using an Operator Lifecycle Manager (OLM).
Run an operator as a deployment
This blog post is about: How to run the example Multi Tenancy Frontend Operator as a deployment on a Kubernetes cluster.
How to extend a Custom Resource Definition for a GO Operator?
That blog post is about some basics how to extend a Custom Resource Definition in a GO Operator. For an Operator implementation you need a Custom Resource Definition and a controller implementation. The Custom Resource Definition for an operator is the basic first step to extend the Kubernetes API with your own functionalities. Usually you create a Custom Resource Definition before you write the controller for your operator.
How to delete services, secrets, and deployments related to a Custom Resource Object in a GO Operator?
This blog post is related to the blog post DEVELOP A SIMPLE OPERATOR TO DEPLOY A WEB APPLICATION USING THE GO OPERATOR SDK. In that last blog post we addressed the topic get a web frontend application running on Kubernetes using a GO Operator. An important part in that scenario is also, how to manage the clean-up for an application instance and it’s related Kubernetes resources and objects created by the operator based on the Custom Resource Object, or: How to delete services, secrets, and deployments related to a Custom Resource Object in a GO Operator?
Debug a Kubernetes Operator written in GO
In this blog post I want to share how to debug a GO Operator on your local machine on macOS. Adam de Leeuw and I verified it in different GO operator projects. Sometimes you find on Google information which uses the older Operator SDK. The following instructions worked for us in March 2022. 😉
Additional notes related to operator development
This blog post is just a list or let me say this is an addition to my last blog post Let’s get started with the development of operators using the GO SDK "one additional road" to get started with operator development from a more technical perspective.
