Kubernetes Operator Development Training

This training course takes an in-depth look at Kubernetes operator development. It focuses on adding your own APIs to a Kubernetes cluster (via CRDs) and best practices such as unit testing, versioning, and debugging, which we at inovex have learned over the past few years while developing operators for many customer projects.

Description

This training takes an in-depth look at Kubernetes operator development. It covers how to add your own APIs to a Kubernetes cluster (via CRDs) and also best practices like unit testing, versioning, or debugging, which we learned at inovex while developing operators in multiple customer projects in the last couple of years.

After becoming familiar with Kubernetes fundamentals, many developers want to offer services like databases or key/value stores inside a Kubernetes cluster so that they can be configured by other developers using Kubernetes-native configuration mechanisms. The solution Kubernetes offers for this is to write and publish an operator for the service in question.

The training offers a very hands-on approach to this topic: throughout the course, participants develop their own operators (including an operator for MinIO, which offers access to S3-compatible storage) and get to apply all concepts and best practices in real life.

Our training approach

From the needs analysis to the awarding of certificates, we offer customized training courses, flexibly designed and carried out according to your requirements.

If you are interested in in-house training, we will start by identifying your needs and discussing your objectives. This discussion forms the basis for an initial offer.

As soon as the framework data has been clarified, our trainers start adapting the training content. Many of our training courses have a modular structure and offer the opportunity to design the agenda flexibly. Training courses that prepare for certifications, on the other hand, are less flexible. Here, however, you can set the content focus according to your wishes.

You will receive all relevant information in advance of the training. The training will then take place in the room of your choice and at the agreed time. Our trainers will adapt to your requirements.

After completing the training, all participants receive a certificate confirming their participation. You will also have the opportunity to give us feedback on the content and the course. We are always happy to receive praise and suggestions for improvement.
