How to Add ForwardAuth to a New Service

We'll assume the new service is hosted at https://web.jafner.net.

1. Open the traefik-forward-auth client configuration page and add the new site (appended with /_oauth) to the list of valid redirect URIs. E.g. https://web.jafner.net/_oauth.
2. Add the traefik-forward-auth@file Traefik middleware to the service.
3. Start up the new service. Open a new private window and navigate to the new service (https://web.jafner.net). It should redirect to Keycloak with a login prompt.
4. If applicable, disable any local auth.

Export and Import Realms

Docs on Keycloak.org

Export Realms

With the docker container offline, run: docker-compose run --rm --entrypoint="/opt/keycloak/bin/kc.sh export --dir /opt/keycloak/data/import --users realm_file" keycloak

This will export the contents of each realm to a json file in the import/ directory. /opt/keycloak/data should be the directory that is mounted to the host.

Import Realms

To import realms at startup, replace the startup command with start --import-realm Additionally, you'll need to map the directory containing the files to import (e.g. $KEYCLOAK_DATA/import) to the /opt/keycloak/data/import inside the container.

For each realm to import, run docker-compose run --entrypoint="/opt/keycloak/bin/kc.sh import --file /opt/keycloak/data/import/{REALM_NAME}.json" keycloak (replace {REALM_NAME} with the name of the realm.)
