The simplest way to verify that a connection is possible between a ROSA cluster and an Aurora DB cluster is to deploy
|
|
`psql` on the Openshift cluster and attempt to connect to the writer endpoint.
|
|
|
|
The following command creates a pod in the default namespace and establishes a `psql` connection with the Aurora cluster if possible.
|
|
Upon exiting the pod shell, the pod is deleted.
|
|
|
|
[source,bash]
