• create loadbalancer for the Apex service

• make install
• make run
  • it will run controller locally while communicating with K8S master
  • all controller logs display on the screen
• run below cmd

cat <<EOF | kubectl apply -f -
apiVersion: operator.apexords-operator/v1
kind: ApexOrds
metadata:
 name: apexords-apexdevords
spec:
 # Add fields here
 dbname: apexdevcdb
 dbservice: apexdevpdb
 ordsname: apexdevords
 # apexruntimeonly: True
EOF

• kubectl get apexords

• make docker-build
• make docker-push IMG="some-registry"/apexords-controller
• Modify image locations on yaml files under config/default/
• make deploy
• run below cmd

cat <<EOF | kubectl apply -f -

 # apexruntimeonly: True
EOF

• kubectl get po -n apexords-operator-system
  • find apexords controller pod
• kubectl logs -f controller-pod-name -n apexords-operator-system
  • see controller logs of what happened include password infor

  • username: admin
  • password: find it in controller logs output
