Running the application using odo: 0. Install https://operatorhub.io/operator/service-binding-operator

1. Install https://operatorhub.io/operator/cloud-native-postgresql
2. Create Cluster service to run postgres DB.

cat << EOF | kubectl apply -f -
apiVersion: postgresql.k8s.enterprisedb.io/v1
kind: Cluster
metadata:
  name: cluster-sample
spec:
  instances: 1
  logLevel: info
  primaryUpdateStrategy: unsupervised
  storage:
    size: 1Gi
EOF

3. Run odo add binding from project directory to bind the application with Cluster/cluster-sample service.

$ odo add binding
? Do you want to list services from: current namespace
? Select service instance you want to bind to: cluster-sample (Cluster.postgresql.k8s.enterprisedb.io)
? Enter the Binding's name: todo-cluster-sample
? How do you want to bind the service? Bind As Environment Variables

 ✓  Successfully added the binding to the devfile.
Run `odo dev` to create it on the cluster.
You can automate this command by executing:
  odo add binding --service cluster-sample.Cluster.postgresql.k8s.enterprisedb.io --name todo-cluster-sample --bind-as-files=false

4. Run odo dev.
5. Access the application on port-forwarded URL, for e.g. 127.0.0.1:40001.
