This blog post is about automating the creation of a Red Hat OpenShift cluster on IBM Cloud in a Virtual Private Cloud. I used bash scripting with the IBM Cloud CLI and and the associated IBM Cloud CLI plugins vpc-infrastructure and kubernetes-service. I also use jq to handle json output.

I created the bash automation in combination of the IBM Cloud documentation and tutorials and my blog post about the automated setup of a simple Virtual Private Cloud.  It’s more about learning and not so much for production.

These are the three resources I used in the IBM Cloud documentation:

I’m not going to show every function of the bash script in this blog post. For details, please visit the script in the GitHub project.

This blog post is about an example usage of the awesome tutorial made by Masa Abushamleh at IBM Developer called Secure routes for your microservices on Red Hat OpenShift. I applied the content, with some small modifications, to my existing example application. It’s the same application I used in this blog post Using the internal OpenShift container registry to deploy an application.

This cheat sheet is about, how to configure a project in an IBM Cloud Red Hat OpenShift to access the IBM Cloud Container Registry. We use an image pull secret to access container images from IBM Cloud Container Registries. The cheat sheet combines different steps, which are available in the IBM Cloud documentation you find here.

We configure a created project in OpenShift to access two different IBM Cloud Container Registries.

The IBM Cloud Red Hat OpenShift cluster is a part of IBM Cloud Account ONE.

The image below shows a simplified architecture overview:

Note: The cheat sheet references to source code, which is available in that example GitHub project. In case you want to follow the steps, you can clone the GitHub project to your local computer.
