Automated creation of a Red Hat OpenShift cluster on IBM Cloud using the existing CLIs and plugins

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.
