Modify the Template for New Projects

https://docs.openshift.com/container-platform/latest/admin_guide/managing_projects.html#modifying-the-template-for-new-projects

1. Start with the current default project template:

oadm create-bootstrap-project-template -o yaml > new-project-template.yaml

It will produce a file similar to this: default new project template

2. The file content can be modified by adding new objects or modifying existing objects.

3. Once the template has been modified, it must be loaded into the default namespace:

oc create -f ./new-project-template.yaml -n default

4. Modify master-config.yaml projectRequestTemplate as follows:

...
projectConfig:
  projectRequestTemplate: "default/project-request"
  ...

The "project-request" name comes from the oadm-generated template:

apiVersion: v1
kind: Template
metadata:
  [...]
  name: project-request
