View source for Oracle: Run Oracle DB on Redhat OpenShift

Based on this work: https://github.com/m-g-k/Running-Oracle-Database-23c-and-23ai-Free-on-OpenShift


= Procedure =
 
1) Create a new project (namespace):

 oc new-project oracle-db

2) Create a Service Account which you will use to run the database:

 oc create sa oracle-sa

3) Configure Security Context Constraint (SCC)

 oc adm policy add-scc-to-user anyuid -z oracle-sa

Check with

 oc adm policy who-can use scc anyuid

4) Create a secret to store the default password for Oracle :

 oc create secret generic oracle-db-pass --from-literal=password=<your_password_here>

5) Create file deployment.yaml
