  1. Do a backup of the built-in database.

    instance=keycloak
namespace=syn-${instance}

kubectl -n "${namespace}" exec -ti keycloak-postgresql-0 -c postgresql -- sh -c 'PGDATABASE="$POSTGRES_DATABASE" PGUSER="$POSTGRES_USER" PGPASSWORD="$POSTGRES_PASSWORD" pg_dump --clean' > keycloak-postgresql-$(date +%F-%H-%M-%S).sql
