That blog post is about an easy example to get your custom logs of your operator, when the operator is running on a Kubernetes cluster. That blog post does reference an example GitHub project called Example Tenancy Frontend Operator you can use to verify the steps. (branch monitor-grafana-operator) In this project I wrote a short custom logging that... Continue Reading →
make: *** [generate] Error 127
Maybe you will get the following error when you try to work with a go operator-sdk project you cloned from GitHub. MAKE: *** [GENERATE] ERROR 127
Example for an installation and an initial configuration of the Grafana operator

Monitor your custom operator with Prometheus
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 š of the road). We will only focus on:how it basically works and not why or what we should do in monitoring.
Add a conversion webhook to an operator to convert API versions
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 →
A simple GO operator development learning journey
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.
Add a new API version to an existing 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).
Deploy an operator without the Operator SDK
That is the next blog post related to operators. Now itās 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).
Run an operator using a bundle with anĀ Operator Lifecycle Manager (OLM)
In that blog post we focus on get the operator installed using the bundle running on a Kubernetes cluster with anĀ Operator Lifecycle Manager (OLM)Ā installed. Surely, theĀ Go Lang tutorialĀ andĀ Getting started OLMĀ can be useful in that context.
How to create a bundle for an operator?
