As I wanted to transfer the database from one kubernetes cluster to a new one, I had to find a way to do this. And with a bit of trial and error I succeeded. So for future reference, and the hope that this might help someone, I figured I would write it down.
First we will transfer the database to our file system:
// pod-name name of the postgres pod // postgres-user database user that is able to access the database // database-name name of the database kubectl exec [pod-name] -- bash -c "pg_dump -U [postgres-user] [database-name]" > database.
