Today’s blog post is about the awesome IBM Garage Cloud Native Toolkit to support continuous integration and continuous delivery (CICD).
I want to provide a basic overview from my perspective, which I structured in following sections:
Kubernetes Operators are an awesome way to simplify work for developers to setup and maintain complex applications in Kubernetes or Red Hat OpenShift.
The IBM Cloud Operator provides you the ability to bind IBM Cloud services to your applications running in Kubernetes or RedHat OpenShift and create, update, and delete IBM Cloud services from within the cluster by calling Kubernetes APIs, instead of needing to use several IBM Cloud APIs in addition to configuring your app for Kubernetes.
That example shows how to bind an existing Cloudant service instance in IBM Cloud to an application running in Red Hat OpenShift. The content of the example is related to the usage of the Red Hat OpenShift with IBM Cloud Open Labs. In these labs you can use a preconfigured OpenShift environment for four hours at no charge to run workshops by your own. By the way, here you can find the related source code for the examples.

Ask your human Operator to do all the complicated ugly work for you!
… or write your own Operator, if you are the expert and you know how the complicated ugly work, works in detail. This is how you can make sure it works in the future 😉
For those of you who don’t know Kubernetes Operators in combination with Ansible, let me just give you a very simplified description from my point of view:
Even a student with minimal knowledge of Kubernetes should be able to install a highly complex container-based application on top of Kubernetes or OpenShift. Eliminate the manual interaction effort as much as possible to deploy, run, and maintain your containerized application on Kubernetes or OpenShift with your Operator implementation.
During my search on the internet, how to build an own custom Kubernetes Operator, I came along to that awesome YouTube video with a talk from Keith Tenzer, he gave in 2020 on the Open Infrastructure Foundation Summit called “Building Kubernetes Operators with the Operator Framework and Ansible”.
