Keycloak is an open source identity and access management solution. By default Keycloak uses an embedded H2 database.
This should be sufficient for development on the local machine, but for production we will replace it with a MySQL standalone database. Simply, download Keycloak from the Keycloak site. Even you can go with the previous release. Keycloak comes in a few different flavors. You can also start Keycloak on Docker or on OpenShift.
You can also install Keycloak into an existing WildFly server. Hi, I am confused after this section.

With its proven performance, reliability and ease-of-use, MySQL has become the leading database choice for web-based applications, covering the entire range from personal projects and websites, via e-commerce and information services, all the way to high profile web properties including Facebook, Twitter, YouTube, Yahoo!
See the list above for relevant tags. The following command starts another mysql container instance and runs the mysql command line client against your original mysql container, allowing you to execute SQL statements against your database instance:.
Run docker stack deploy -c stack. The docker exec command allows you to run commands inside a Docker container.
Server Installation and Configuration Guide
The following command line will give you a bash shell inside your mysql container:. Please inspect the relevant files and directories within the mysql image itself for more details. Many configuration options can be passed as flags to mysqld. This will give you the flexibility to customize the container without needing a cnf file.
For example, if you want to change the default encoding and collation for all tables to use UTF-8 utf8mb4 just run the following:. When you start the mysql image, you can adjust the configuration of the MySQL instance by passing one or more environment variables on the docker run command line. Do note that none of the variables below will have any effect if you start the container with a data directory that already contains a database: any pre-existing database will always be left untouched on container startup.
This variable is mandatory and specifies the password that will be set for the MySQL root superuser account. In the above example, it was set to my-secret-pw. This variable is optional and allows you to specify the name of a database to be created on image startup.
These variables are optional, used in conjunction to create a new user and to set that user's password. Both variables are required for a user to be created.
This is an optional variable. Set to yes to allow the container to be started with a blank password for the root user. NOTE : Setting this variable to yes is not recommended unless you really know what you are doing, since this will leave your MySQL instance completely unprotected, allowing anyone to gain complete superuser access.
Set to yes to generate a random initial password for the root user using pwgen. Using this option on MySQL 5. For example:. When a container is started for the first time, a new database with the specified name will be created and initialized with the provided configuration variables. Furthermore, it will execute files with extensions. Files will be executed in alphabetical order. You can easily populate your mysql services by mounting a SQL dump into that directory and provide custom images with contributed data.
Important note: There are several ways to store data used by applications that run in Docker containers.Authorization Services. The purpose of this guide is to walk through the steps that need to be completed prior to booting up the Keycloak server for the first time. If you just want to test drive Keycloak, it pretty much runs out of the box with its own embedded and local-only database.
This guide walks through each and every aspect of any pre-boot decisions and setup you must do prior to deploying the server.
Many aspects of configuring Keycloak revolve around WildFly configuration elements. Often this guide will direct you to documentation outside of the manual if you want to dive into more detail. Keycloak is built on top of the WildFly application server and its sub-projects like Infinispan for caching and Hibernate for persistence. This guide only covers basics for infrastructure-level configuration. It is highly recommended that you peruse the documentation for WildFly and its sub projects.
Here is the link to the documentation:. Installing Keycloak is as simple as downloading it and unzipping it. This chapter reviews system requirements as well as the directory structure of the distribution.
Keycloak requires an external shared database if you want to run in a cluster. Please see the database configuration section of this guide for more information. Network multicast support on your machine if you want to run in a cluster.
Keycloak can be clustered without multicast, but this requires a bunch of configuration changes. Please see the clustering section of this guide for more information. The 'keycloak It contains nothing other than the scripts and binaries to run the Keycloak Server. The 'keycloak-overlay We do not support users that want to run their applications and Keycloak on the same server instance.
To install the Keycloak Service Pack, just unzip it in the root directory of your WildFly distribution, open the bin directory in a shell and run. To unpack of these files run the unzip or gunzip and tar utilities.
This contains various scripts to either boot the server or perform some other management action on the server. This contains configuration files and working directory when running Keycloak in domain mode. This contains configuration files and working directory when running Keycloak in standalone mode.
If you are writing extensions to Keycloak, you can put your extensions here. See the Server Developer Guide for more information on this.
Here you can modify an existing theme or create your own.
Before deploying Keycloak in a production environment you need to decide which type of operating mode you are going to use. Will you run Keycloak within a cluster? Do you want a centralized way to manage your server configurations?
Your choice of operating mode affects how you configure databases, configure caching and even how you boot the server.
Standalone operating mode is only useful when you want to run one, and only one Keycloak server instance. It is not usable for clustered deployments and all caches are non-distributed and local-only.

I am trying to start a Keycloak instance which uses a custom mysql database instead of the embedded H2. Since I am planning to use docker, I created a network for Keyclock docker to communicate with mysql. I am expecting keycloak to access the database keycloak with username ku and password kupw. I ensured that the database as well as the user is created in mysql.
With mysql up and running, i started the keycloak docker to connect to mysql with user ku accessing the database keycloak. But I could see that the tables that got created as a result of executing this process inside the keycloak database. Not sure if this is the right place to post this question.
Doing so as requested by stackoverflow members. Maybe I need more morning coffee, but to me it looks like your MySQL ku user does not have any privileges granted, so the application fails as well. Sign up to join this community.

Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. So I am trying to set up a Keycloak with Mysql back-end using docker compose but no matter what I do, Keycloak refuses to actually create any tables or store any data in the database even though they both start just fine. If anyone knows what I am doing wrong, I would be eternally grateful.
Additionally those services starting process should be separated two docker-compose files or one service waiting for another because Keycloak is not aware of when does your MySQL finish initializing the DB - meaning it'll proceed and throw exception when it will not be able to access the MySQL DB as the DB will still be starting up. I didn't manage to actually run it successfully because of a network problem I'm still resolving, making it impossible for keycloak to reach mysql service over the network.
Although OP might find it very useful as this change will alter connection from embedded H2 into external MySQL which is the asked question. And if the DB is accessible, it will actually utilize it. I'll be adding edits to this answer when I resolve my network issue to keep it up to date. It's worth noting that Keycloak 3. Learn more. No data saved Ask Question. Asked 1 year, 11 months ago.

It wrap up a piece of software in a complete file system that contains everything it needs to run: code, run-time, system tools, system libraries — anything you can install on a server. This guarantees that it will always run the same, regardless of the environment it is running in. The same Linux kernel and libraries can be shared between multiple containers running on the host.
Keycloak comes with its own embedded Java-based relational database called H2. This is the default database that Keycloak will use to persist data and really only exists so that you can run the authentication server out of the box. We highly recommend that you replace it with a more production ready external database. The H2 database is not very viable in high concurrency situations and should not be used in a cluster either.
The purpose of this chapter is to show you how to connect Keycloak to a more mature database. Docker hub provides images for all the software and tools. There are many Keycloak-mysql Docker images available, but it is always better to go with the official release.
As they are highly optimised, bug free and stable. You can download to your computer using pull command. After that we can list down the docker images. After an image has been downloaded, you may then run a container using the downloaded image with the run sub command. Looks good. MySQL on port Use the following command to see what happened during the container startup:.
Run the inspect command:. Docker allocates a dynamic IP address on every running container. Whenever a container is restarted, you will get a new IP address. You can get the IP address range from the Docker network interface in the Linux box. To sort this issue there is an option called —link. Your email address will not be published.

Important in this blog is that the whole process will be described. I attended a couple of keycloak sessions during Javaone this year and during these sessions the illusion was created that adding Keycloak as the security provider for your application is very easy and almost non-invasive for your code.
What they did not tell you that configuring a server that could use keycloak was not as trivial. This blog will also expose a java web application with rest end-points to show how the auth works. Time to maybe read more here about what the following commands mean. If you are not interested in accessing the ivonet-postgres-data with external tools, then you can eliminate the -p parameter from the ivonet-keycloak-postgres command.
As you might have noticed I gave the external port I did this because on my production environment I already have a native postgres running and am migrating slowly. So now we have a setup that might work :- lets try it out and enter the following in the terminal:.
So now we have a keycloak auth server up and running.
Run Keycloak Server in a Docker Container
This is the part not mentioned in the sessions I followed and what stumped me in the beginning. Wel as you may have guessed you actually do need something else. Wildfly is the obvious choise because jboss is the major contributor to keycloak. You need an adaptor installed on the server, because you want the EE container to recognize keycloak as a security provider.
JBoss provides a docker image for that to but as of the time of this writing it was in wildfly 9. Final and on keycloak 1. Final and the most current versions are 9. Final for wildfly and 1. Final for keycloak so I upgraded from the latest default wildfly image. See this Dockerfile for the one I used to build my own version of Wilfly with the keycloak adapter installed.
This Dockerfile is of course the product of some trial and error I had to find out if the install was correct. This part will not be explained here, but if you want more input on this subject, drop me a line. My production environment is an Ubuntu Linux distribution and I access all my sites through Apache2 VirtualHost configurations.
Apache is my front proxy and directs all based on servername resolves and ports. When trying to put my keycloak docker construction as described above behind an Apache ProxyPass construction it all went to pieces. As we are talking about a security solution it seems kinda important to do all through https.
So I went to letsencrypt and got myself a certificate and proxypassed my content to the inner docker endpoint. Solving this was way more hassle than I expected and took my about two evenings of googling and reading to fix. These settings can be found in the documentation but are not easy to find. Now I have no mixed content messages anymore and a certificate that is not self signed.
Great stuff. The extraction will take place and after that the server is still running.
