= 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 enable the service binding connection and trigger the Operator reconciliation.
|
|
+
|
|
The output verifies that the database instance is created:

|
[source,terminal]

----

postgrescluster.postgres-operator.crunchydata.com/hippo created
|

|
|
|
|
. After you have created the database instance, ensure that all the pods in the `my-petclinic` namespace are running:
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ oc get pods -n my-petclinic
|
|
----
|
|
+
|
|
The output, which takes a few minutes to display, verifies that the database is created and configured:

|
|
.Example output

|
[source,terminal]

After the database is configured, you can deploy the sample application and connect it to the database service. |
