-[![Build Status](https://drone.autonomic.zone/api/badges/coop-cloud/keycloak/status.svg)](https://drone.autonomic.zone/coop-cloud/keycloak)
+Wiki Cafe's configuration for a Keycloak deployment. Originally slimmed down from an `abra` [recipe](https://git.coopcloud.tech/coop-cloud/keycloak) by [Co-op Cloud](https://coopcloud.tech/).
 
-[Keycloak](https://www.keycloak.org) + Coöp Cloud.
+## Extensions
 
-<!-- metadata -->
-* **Category**: Apps
-* **Status**: 2, beta
-* **Image**: [`jboss/keycloak`](https://hub.docker.com/r/jboss/keycloak), 4, upstream
-* **Healthcheck**: Yes
-* **Backups**: ?
-* **Email**: 1
-* **Tests**: 2
-* **SSO**: N/A
-<!-- endmetadata -->
+This stack includes the following extensions:
 
-## Basic usage
+- (keycloak-events)[https://github.com/p2-inc/keycloak-events]
+- (keycloak-restrict-client-auth)[https://github.com/sventorben/keycloak-restrict-client-auth]
 
-1. Set up Docker Swarm and [`abra`][abra]
-2. Deploy [`coop-cloud/traefik`][cc-traefik]
-3. `abra app new keycloak --secrets` (optionally with `--pass` if you'd like
-   to save secrets in `pass`)
-4. `abra app YOURAPPDOMAIN config` - be sure to change `$DOMAIN` to something that resolves to
-   your Docker swarm box
-5. `abra app YOURAPPDOMAIN deploy`
+### Installing extensions
 
-## How do I setup a custom theme?
+To install the extensions, download their JAR files and place them in the `providers` directory. Then, restart the Keycloak container.
 
-Check [this approach](https://git.autonomic.zone/ruangrupa/login.lumbung.space).
+You can update an extension by simply replacing the old JAR file with the new one.
 
-## How do I create another admin user?
+## Deploying the app with Docker Swarm
 
-- Under the `Master` realm > `Users` > `Add user`
-- Create the user and set a temporary password
-- Under the `Role Mappings` tab, move `admin` from `Available Roles` into `Assigned Roles`
+Set the environment variables from the .env file during the shell session.
 
-## How do I configure Keycloak login for..
+```
+set -a && source .env && set +a
+```
 
-- [Nextcloud][nextcloud]
-- [Peertube][peertube]
+Set the secrets.

-
-Not all versions are affected but they're suggesting that people upgrade soon.
-
-As per usual, this upgrade didn't go too smoothly and I ended up having to
-undeploy and deploy the new versions. The healtcheck kept failing on the new
-instance when trying to deploy alongside the existing old version. Idk, some
-docker weirdness.

-No app data errors discovered after upgrade.
