Keycloak Export in Kubernetes

Raw

keycloak-export-import-k8s.md

Perform Keycloak Export and Import on Kubernetes

Setup Keycloak in non-HA mode (replica 1)
Disable UserFederation
You might have to increase the resource limits to avoid that pod beeing killed by memory or CPU limits

See Keycloak Documentation for more details.

Export

Trigger export (called from pod keycloak-0):

kubectl exec -it keycloak-0 bash

/opt/jboss/keycloak/bin/standalone.sh -Dkeycloak.migration.action=export -Dkeycloak.migration.provider=dir -Dkeycloak.migration.dir=/opt/jboss/keycloak-export -Dkeycloak.migration.usersExportStrategy=DIFFERENT_FILES -Dkeycloak.migration.usersPerFile=100 -Djboss.http.port=8888 -Djboss.https.port=9999 -Djboss.management.http.port=7777 -Djboss.management.https.port=7776

After succesful export keylcoak finish startup.

WFLYSRV0025: Keycloak 4.5.0.Final (WildFly Core 5.0.0.Final) started in 86826ms

Shutdown by pressing Ctrl+C

Copy files (on local machine):

mkdir kc-export
cd kc-export
kubectl cp keycloak-0:/opt/jboss/keycloak-export .

See: https://stackoverflow.com/a/47198081/7290164

Import

Copy files from local machine to pod:

cd kc-export
kubectl cp . keycloak-0:/opt/jboss/keycloak-export

Connect to pod and trigger import for a specific realm:

kubectl exec -it keycloak-0 bash

/opt/jboss/keycloak/bin/standalone.sh -Dkeycloak.migration.action=import -Dkeycloak.migration.provider=dir -Dkeycloak.migration.dir=/opt/jboss/keycloak-export -Dkeycloak.migration.usersExportStrategy=DIFFERENT_FILES -Dkeycloak.migration.usersPerFile=100 -Djboss.http.port=8888 -Djboss.https.port=9999 -Djboss.management.http.port=7777 -Djboss.management.https.port=7776 -Dkeycloak.migration.realmName=<my-realm-name>

After succesful import keylcoak finish startup.

There is no need for a PV (beside the fact that keycloak is usually running as a StatefulSet which comes with a PV).
The export is done inside the Pod, afterwards the dump is copied via kubectl to your local machine.

CPU limit will only throttle you, means export might take very long. But with insufficient mem, your Pod become OOM killed (see lastState.terminated.reason)

lastState.terminated.reason

Seems that could be the reason, I will increase the resources! thank you for you quick answer
and for the help!

Now the Keycloak server is not being killed, but I am getting this error below during the export task, any idea of the meaning of this error? I am trying to investigate but I did not find anything at the moment.

Thanks for this.

I had some trouble with the WildFly Undertow webserver port which was bound on the same port as the 'normal' running Keycloak process in the background.

I fixed this issue by adding -Djboss.socket.binding.port-offset=100

This offsets all used TCP/IP ports by 100, including the Undertow port.

Additional info for Bitnami image users:

Add add -c=standalone-ha.xml to your export command. Bitnami uses this config file for the database resource.

Thanks for this. When I export the realm, I am seeing the client secret is masked for clientAuthenticatorType as "client-jwt". Did you also face this problem. Is there any way to export the client secret also.

I’m sure that’s a deliberate security measure. It may be accessible through the UI or another CLI approach, but it’s likely possible to configure that in the new step (wherever it’s being imported) manually.

@axdotl thanks a lot.
