Download Keycloak Docker
Haldis Momeni
Switched to m1 mac a week ago and I cannot get my application up and running with docker because of the jboss/keycloak image not working as expected. Getting the following message from the container when trying to access localhost:8080
The location for building a quarkus version of keycloak has changed, so this method will not work anymore for any major releases greater than 16. But the following script will. Just save it as an sh. file and execute it in your terminal. By enabling the last line, this will also directly start an instance of Keycloak.The version number can be changed, but this is only tested for M1 chips and version 17.0.0.
This pulls the jboss/keycloak image from docker hub and then it runs it exposing the port 8080 within the container to the host machine. It also uses the environment variables in the .txt file (which contains info on the database endpoint you wish to connect keycloak to to persist data).
To get the actual data I want imported, I went to the required realm and simply clicked the export button with clients etc. selected. This downloaded a file to my browser which I now want imported when I build my docker containers
First you need to copy the file into your container before you can import it into Keycloak. You could place your realm-export.json in a folder next to the docker-compose.yml, lets say we call it imports. This can be achieved using volumes:. Once the file has been copied into the container then you can use command: as you were before, pointing at the correct file within the container.
I'm experimenting with keycloak and the integrated docker registry v2 auth. Everything is working fine with that. However, currently there is no real authorization layer and having a look at the sourcecode on github I can see that there is a class AllowAllDockerProtocolMapper which automatically grants all permissions for the docker registry to the logged-in user.
Right now, however I am struggling to get a simple working example up and running. I read the keycloak guide for spi at _development/index.html#_providers and had a look at some examples on github but right now the deployed module does not seem to be picked up by keycloak.
KEYCLOAK_HOME/bin/jboss-cli.sh --command="module add --name=a.b.c.d.docker-user-namespace-mapper --resources=/build/libs/docker-user-namespace-mapper.jar --dependencies=org.keycloak:keycloak-services,org.keycloak.keycloak-server-spi-private,org.keycloak:keycloak-server-spi".
When i go to the Admin cli, and try to add a new mapper to a a docker-v2 client, the new mapper does not show up and everything seems to be the same as before the deployment. During deployment and server restart no errors are thrown. Can anybody help me to get this docker mapper correctly deployed?
The module was not picked up by Keycloak because I was editing the wrong config file. Instead of adding the provider to standalone.xml I had to add it to standalone-ha.xml. This is because I actually use the official Keycloak docker image jboss/keycloak and having a look at their startup script docker-entrypoint.sh it becomes clear that standalone-ha.xml is used. You can find more information here : Keycloak SPI Providers and layers not loading when using Docker.
Even without an image upgrade, simply deleting and restarting the container leads to loss of the new realm I've configured. I end up with the initial setup, the master realm, the default admin password from the docker-compose file instead of the one I've set up later through the web gui. Looks to me as re-creating the conatiner leads to Keycloak starting in initial setup mode, and not detecting that the database is already fully set up
Shame on me, I've already deployed to production, and migrated some 30 users into it. Backups saved my life so far, but now I'm stuck with the existing container that I can start/stop (thus data is not only in RAM, it is stored on the disk), but I can't re-create the container. Therefore also no way to migrate to newer versions of keycloak
Now the question is : how do I get my production data out of the keycloak container, in order to have it available in a new container ? The keycloak container has no volume mounted, so there must be some data inside. Postgres container has the postgres_data volume/directory which also contains data from the last days. So something is actually inside the DB, but not the whole thing... What is missing and how to extract it ?
P.S.: The described procedure of adding keycloak to Seafile is still current. The only thing that changed in the base configuration with KC 19 is that the /auth/ directory was removed. So just leave this in all urls out and it should work.
I'm having an issue adding SSL certificate to Keycloak that is running on docker.I bought an SSL Certificate from Godaddy, but don't know how to add Keycloak on docker.I was looking through Google but nothing found yet.
Go to File Station and open the docker folder. Inside the docker folder, create one new folder and name it keycloakdb. Follow the instructions in the image below.

Are you using nginx as a reverse proxy? I am trying to get this setup as well and need help. I am new to both rocket chat and keycloak. I have keycloak and rocket chat setup with containers on the same docker network, did extra_hosts, and it seems like I come to the login page, I get redirected to keycloak, I login and then get brought back to the login page. Any insights would help greatly.
I tried to run the flowable-ui apps with keycloak (with docker-compose docker-compose
I noticed you are using two realms (master and flowable) in docker-compose.
flowable-idm app can only calls users who are created in the master realm.
thank you for explaining to me the objective of this separation.
To know more about each of those, follow below documentation links:Keycloak image: docker_container: _container_module.html#docker-container-moduleAnsible docker_image: _image_module.html?highlight=docker_imageOk so now we have our creation playbook ready, we may start it.1ansible-playbook create.ymlIf you navigate to :8080/auth you should be greeted by keycloak splage page.
I've been trying to get keycloak running for a bit now. I had it going using the legacy tag but it seems like bad practice to get started with a legacy version. So I wanted to get the most recent version running. This is my docker compose config, but somehow It wont work.It has something todo with the database connection but I cant figure out what's going wrong.
The new thing in 17.0.0 is the use of KEYCLOAK_ADMIN and KEYCLOAK_ADMIN_PASSWORD environment variables. Prior to 17.0.0, to create an initial administrator account, we had to execute the /opt/jboss/keycloak/bin/add-user-keycloak.sh. script and pass -u user -p pass arguments. If you read some of my previous article, you maybe remember this command:
For Docker Compose, you can scale the Keycloak service by updating the docker-compose.yml file and increasing the number of replicas for the Keycloak service. After making the changes, redeploy your updated Docker Compose configuration.
You are almost done, you just need to wait for azure infrastructure to create your new app service and keycloak is ready to run, but you need first to go to configuration section and add some basic settings
The only problem of this approach is: if you stop the service, and container will be restarted from scratch, you will lose all of your data. This is a standard problem if you use KeyCloak docker container using internal database (H2). Clearly the correct solution is using another container with a Database or an external database that is capable to store data surviving a reboot.
Luckily enough we have a feature in preview that allows us to specify a Docker compose yml file for the app service. This will give us the option to easily map the internal directory where keycloak stores data to a subfolder of the /home folder, this will make H2 internal database survive a reboot.
This configuration will create a volume1 with the local driver, and point the internal folder /opt/keycloak/data to the /home/data folder of the host machine. Given that thanks to the WEBSITES_ENABLE_APP_SERVICE_STORAGE setting, the /home folder is persisted, the H2 database used by keycloak will be persisted too.
Here, we provide both a source and a target path, making those volumes bind mounts. This type of volume is fine for a dev environment, but using named volumes or copying files directly in the container is more advised for production environment, except if you want full control of your filesystem, and apply modifications outside docker.
Before turning to the next section, stop the container with the command docker stop keycloak-dev since the new container will require the same host port. Delete it with docker rm keycloak-dev as it is not being used any longer.
Because the two environment variables KEYCLOAK_ADMIN and KEYCLOAK_ADMIN_PASSWORD are defined in the docker-compose/src/main/resources/keycloak.common.env file, an initial user is created during the startup of Keycloak. We strongly advise moving these 2 properties from the keycloak.common.env file to the secrets.env file.
Now you can access the Web Admin Console at :8080/ with user admin and password admin (as initially defined in docker-compose/src/main/resources/keycloak.common.env) and find the already created new realms example1 and example2.
Please note, if Keycloak is running within a container, the JDBC URL for the PostgreSQL connection must be changed from hostname localhost to either the service name (if running in the same docker network) or to host.docker.internal (if the port is exposed there). This change can be done by copying the KC_DB_URL property from docker-compose/src/main/resources/keycloak.common.env and overriding it in the docker-compose/src/main/resources/keycloak.specific.env file with the hostname host.docker.internal.
