What is CodeReady Containers and why?
When you want to set up an Openshift cluster for personal use eg learning, development, doing demos, etc., you have the following choices:
- Installer Provisioned Infrastructure (IPI) requires 3 master and 2 worker + 1 Bootstrap servers (on AWS, Azure). Note that the Bootstrap server is only needed during the creation of the Openshift cluster and not after the setup.
- User Provisioned Infrastructure (UPI) requires 3 masters and 2 workers + Bootstrap servers (VMs and bare metal)
- CodeReady Containers on your laptop or desktop computer. CodeReady Containers allows you to run a minimal, preconfigured OpenShift 4.X cluster to your local laptop or desktop computer for development and testing purposes.
For personal use and learning purposes, Options 3 is orders of magnitude cheaper (1 laptop vs 5 AWS EC2 instances or VMs) and easier to set up compared to Options 1 and 2. Continue reading REMOTE ACCESS TO YOUR PERSONAL CODEREADY CONTAINERS (OPENSHIFT) ENVIRONMENT
