Storage Configurations

The Keycloak setup for minikube supports several storage configurations.

Keycloak provides two storage implementations:

Legacy Storage
New storage (also called Map Storage)

Default Setup

When running Keycloak on the minikube setup, it will as default run Keycloak with the latest nightly images of the Keycloak Operator and Keycloak with a PostgreSQL database and the legacy store.

See Accessing the PostgreSQL database inside minikube for more information.
