A repository of artifacts to improve the experience of install OpenShift 4 using the User-Provisioned Infrastructure (UPI) method of deployment.
The OpenShift 4 documentation for UPI provides a collection of CloudFormation templates to deploy OpenShift 4 infrastructure components. However, these CloudFormation templates do not exactly represent the setup that you would get if you were to do use the Installer-Provision Infrastructure (IPI) method of deployment. Namely, it names things differently and misses quite a few tags that are critical to ensuring that you can take advantage of all cloud integration features in OpenShift 4.
To improve that experience and to ensure the infrastructure provided by default matches as closely as possible to what you would get if you used the IPI method of deployment, this repository includes modified versions of each of the CloudFormation templates to fix those issues.
You can find the templates here:
| Template | Original | Modified |
|---|---|---|
| VPC | original | modified |
| Security | original | modified |
Also included is a playbook that ties each of the CloudFormation templates together by matching the outputs of CloudFormation stacks to parameters to templates that run later in the process, including taking user input for required parameters and some optional parameters.
