I’m trying to get a basic example of shinyproxy working with keycloak. This is my `Dockerfile` ```auto FROM openjdk:11-jre RUN mkdir -p /opt/shinyproxy/ RUN wget https://www.shinyproxy.io/downloads/shinyproxy-2.3.1.jar -O /opt/shinyproxy/shinyproxy.jar COPY application.yml /opt/shinyproxy/application.yml WORKDIR /opt/shinyproxy/ CMD ["java", "-jar", "/opt/shinyproxy/shinyproxy.jar"] ``` This is my `docker-compose.yml` ```auto version: "3.7" services: mysql: image: mysql:5.7 volumes: - mysqldata:/var/lib/mysql environment: MYSQL_ROOT_PASSWORD: root MYSQL_DATABASE: keycloak MYSQL_USER: keycloak MYSQL_PASSWORD: password keycloak: image: quay.io/keycloak/keycloak:latest environment: DB_VENDOR: MYSQL DB_ADDR: mysql DB_DATABASE: keycloak DB_USER: keycloak DB_PASSWORD: password KEYCLOAK_USER: admin KEYCLOAK_PASSWORD: Pa55w0rd PROXY_ADDRESS_FORWARDING: 'true' ports: - 8010:8080 #networks: # - shinyproxy-net depends_on: - mysql shinyproxy: build: . image: shinyproxy ports: - '8020:8080' networks: - shinyproxy-net volumes: - /var/run/docker.sock:/var/run/docker.sock networks: shinyproxy-net: external: true volumes: mysqldata: driver: local ``` This is my `application.yml` ```auto proxy: port: 8080 authentication: keycloak useForwardHeaders: true # not sure if necessary or not admin-groups: admins keycloak: realm: shinyproxy auth-server-url: http://localhost:8010/auth resource: shinyproxy credentials-secret: aa205d81-ae00-4b59-bca6-4c41074c633c docker: internal-networking: true specs: - id: 01_hello display-name: Hello Application description: Application which demonstrates the basics of a Shiny app container-cmd: ["R", "-e", "shinyproxy::run_01_hello()"] container-image: openanalytics/shinyproxy-demo container-network: shinyproxy-net - id: 06_tabsets container-cmd: ["R", "-e", "shinyproxy::run_06_tabsets()"] container-image: openanalytics/shinyproxy-demo container-network: shinyproxy-net logging: file: shinyproxy.log ``` When I go to `http://localhost:8020/` and authenticate with the user I created in `http://localhost:8010/` I get a redirected too many times error: ![image](https://support.openanalytics.eu/uploads/default/original/1X/923e52c6516ee73d38ed0716cf6338d76b18f729.png) **What am I doing wrong?** ---

Hi @ignacio82, I’m trying to work through a very similar setup and can’t say that I’ve got everything fully functional yet. Do you think you could post your KeyCloak realm settings? Specifically, the return URI? One thing I did notice is that ShinyProxy can’t hit the Keycloak container using `localhost`. I don’t know why or whether there’s an option to allow this, but my approach has been to use the full IP address in `auth-server-url` - e.g. [http://192.168.1.100:8010/auth](http://192.168.1.100:8010/auth). The same logic would be required in your KeyCloak realm settings. Good luck! Jay ---

I’m having trouble finding the return URI setting? Where is it? ---

Sorry @ignacio82 - I got the KeyCloak terminology wrong. I meant the `Valid Redirect URI's` found in the settings panel of the Client setup. It’s the address KeyCloak sends users back to after they’ve successfully logged in. ---

@JayAchar I’m just using \* there… Maybe that is the problem… Not sure what I should use. What do you have there? ---

I think there are a couple of ways of tackling this, since you can define the base URI, then just include the additional parts in this field. To keep things a bit simpler, I took the approach of including the full **external** IP address which takes you back to the ShinyPorxy server. For you case, this might be something like: ` http://192.168.1.5:8020/*` I had previously tried using `localhost` and ran into problems such as this since I think KC needs to communicate with services via the external IP address. I do believe there’s a way to allow communication through the docker network, but I haven’t managed to get that working unfortunately. Really hope that helps 🙂 ---

It did not work ☹ ```auto This page isn’t working 192.168.86.50 redirected you too many times. Try clearing your cookies. ERR_TOO_MANY_REDIRECTS ``` ---

This issue is because ShinyProxy cannot reach keycloak on localhost. You either have to run all services using `network_mode: host` so that you can use localhost. Or you have to setup keycloak using some public facing URL and use that URL in the shinyproxy configuration as auth-url
