= Creating a PostgreSQL database instance
|
|
|
|
To create a PostgreSQL database instance, you must create a `PostgresCluster` custom resource (CR) and configure the database.

.Procedure
|
|
|
|
. Create the `PostgresCluster` CR in the `my-petclinic` namespace by running the following command in shell:

|
[source,terminal]
|
|
----
|
|
$ oc apply -n my-petclinic -f - << EOD

The annotations added in this `PostgresCluster` CR help in enabling the service binding connection and trigger the Operator reconciliation.

The output verifies that the database instance is created:

|
|
[source,terminal]
|
|
----
|
|
$ oc get pods -n my-petclinic
|
