Unlocking the power of Kubernetes: Create your own resources with CRDs

Kubernetes Custom Resource Definition (CRD ) is like a special tool that makes managing your workloads in Kubernetes easy. It allows you to create your own customized types of resources that fit your specific needs. It's like a power drink in the way it gives you extra energy and helps you manage your Kubernetes environment with ease.
Talk abstract

Kubernetes CRDs are valuable for a number of reasons: First, they empower developers to expand the capabilities of Kubernetes by creating their own custom resources and controllers. This allows for a higher degree of customization and automation of complex tasks within Kubernetes clusters.

Additionally, by allowing developers to create domain-specific abstractions that fit the unique needs of their applications, CRDs promote collaboration and knowledge-sharing within the Kubernetes ecosystem.

However, creating CRDs and controllers can be a challenging task. Fortunately, tools like Operator-sdk exist to generate CRDs and controllers, and package them as an application known as Kubernetes Operators. This simplifies the process of deploying and managing CRDs and controllers on the cluster.

In summary, Kubernetes CRDs offer developers greater control and flexibility over their Kubernetes clusters, while also encouraging collaboration and innovation within the community.

How to deploy Kotlin applications to Kubernetes without Dockerfiles
In this talk Lothar shares how to create docker images with Kotlin and Gradle only. Lothar will showcase a ktor application as well as create and deploy a Docker image that contains the application to a Kubernetes cluster. The deployment happens on the command line only - every code change will trigger an instant deployment of a newly created Docker image to a Kubernetes cluster.
