== Importing a Keycloak Realm

Using the Keycloak Operator, you can perform a realm import for the Keycloak Deployment.

[NOTE]
====
* If a Realm with the same name already exists in Keycloak, it will not be overwritten.

* The Realm Import CR only supports creation of new realms and does not update or delete those. Changes to the realm performed directly on Keycloak are not synced back in the CR.
====

=== Creating a Realm Import Custom Resource

The following is an example of a Realm Import Custom Resource (CR):

[source,yaml]
----
apiVersion: k8s.keycloak.org/v2alpha1
kind: KeycloakRealmImport
metadata:
  name: my-realm-kc
spec:
  keycloakCRName: <name of the keycloak CR>
  realm:
    ...
----

This CR should be created in the same namespace as the Keycloak Deployment CR, defined in the field `keycloakCRName`.
The `realm` field accepts a full https://www.keycloak.org/docs-api/{majorMinorVersion}/rest-api/index.html#_realmrepresentation[RealmRepresentation].

The recommended way to obtain a `RealmRepresentation` is by leveraging the export functionality <@links.server id="importExport"/>.

. Export the Realm to a single file.
. Convert the JSON file to YAML.
. Copy and paste the obtained YAML file as body for the `realm` key, making sure the indentation is correct.

=== Applying the Realm Import CR

Use `kubectl` to create the CR in the correct cluster namespace:

[source,bash]
----
cat <<EOF >> example-realm-import.yaml
apiVersion: k8s.keycloak.org/v2alpha1
kind: KeycloakRealmImport
metadata:
  name: my-realm-kc
spec:
  keycloakCRName: <name of the keycloak CR>
  realm:
    id: example-realm
    realm: example-realm
    displayName: ExampleRealm
    enabled: true
EOF
kubectl apply -f example-realm-import.yaml
----

To check the status of the running import, enter the following command:

[source,bash]
----
kubectl get keycloakrealmimports/my-realm-kc -o go-template='{{range .status.conditions}}CONDITION: {{.type}}{{"\n"}}  STATUS: {{.status}}{{"\n"}}  MESSAGE: {{.message}}{{"\n"}}{{end}}'
----

When the import has successfully completed, the output will look like the following example:

[source,bash]
----
CONDITION: Done
  STATUS: true
  MESSAGE: 
CONDITION: Started
  STATUS: false
  MESSAGE: 
CONDITION: HasErrors
  STATUS: false
  MESSAGE:
----
