That blog post does focus on a basic installation of the Grafana operator to get an understanding how that operator basically works in the context to the two blog posts I made before
hat blog post does focus on a customized monitoring with Prometheus for a custom operator implementation build with the golang Operator SDK. For the monitoring we will use the Prometheus operator. Alain Arom and I inspected that topic and here we show you one example hands-on journey how to get the technical job done. There are a lot of materials out there, but in that blog post we follow an end-to-end scenario for a beginner to intermediate level (without any stop in the middle 😉 of the road). We will only focus on:how it basically works and not why or what we should do in monitoring.
In that blog post we will add a webhook to our existing operator project Multi Tenancy Frontend Operator in the branch update-operator were we created the v2alpha2 API version for the operator in the last blog post "Add a new API version to an existing operator". The final implementation for the current blog post you find in the webhook-gen-operator branch. (details about conversion webhook) Yes, that... Continue Reading →
This is about a personal GO operator development learning journey you can follow along the different blog posts I made about the GO operator development using an own (mostly ;-)) simple example called Multi Tenancy Frontend Operator.
This is my next blog post related to operators. That blog post is about adding a new API version to our existing example Multi Tenancy Frontend Operator. When we have added the new API version we will deploy the changed operator to a Kubernetes cluster using the Operator Lifecycle Manager (OLM).
That is the next blog post related to operators. Now it’s about deploy an operator without the Operator SDK. In the last blog post we used the operator-sdk run bundle command which created for us all needed specifications and images to run the bundle. Therefor we need to take a closer look into the Operator Lifecycle Manager (OLM).
This blog post is about: How to run the example Multi Tenancy Frontend Operator as a deployment on a Kubernetes cluster.
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.
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?
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. 😉
