  • k3d cluster create mycluster
    • This will create 1 docker process (slave and master will be on the same kubernetes node)
  • Kubernetes Secrets to store Database and Oracle Container Registry (OCR) credentials
    • docker login
      • User/pass from from step#1
    • kubectl create secret generic regcred —from-file=.dockerconfigjson=$HOME/.docker/config.json  —
      • Creates Kubernetes secret using OCR credentials
  • Run the commands below
    • kubectl get nodes
    • docker exec -it <ENTER_NODE_NAME_HERE> sh
      • This will shell you into the node
    • Make an oracle folder under /tmp/oracle (this needs to be done on all master/slave nodes)
      • Make an oradata folder (mkdir oradata)
      • Make a scripts folder (mkdir scripts)
        • Make a startup folder (mkdir startup)
          • This is where you can add all SQL files that will be run at startup
        • Make a setup folder (mkdir setup)
    • chmod 777 all folders created under /tmp
  • kubectl apply -f orcldb3.yaml
  • kubectl get pods
    • kubectl describe pod <ENTER_POD_NUMBER_HERE>  (to get details)
    • Kubectl logs <ENTER_POD_NUMBER_HERE> —follow (to see the database be created)

  • kubectl exec -it pods/orcldb-5549d599b-qtsxr — sqlplus pdbadmin/PASS_GOES_HERE@ORCLPDB1

SSH into node
