Proof-of-Concepts & Articles

On ivangfr.github.io, I have compiled my Proof-of-Concepts (PoCs) and articles. You can easily search for the technology you are interested in by using the filter. Who knows, perhaps I have already implemented a PoC or written an article about what you are looking for.

Please, refer to the official Keycloak documentation at https://www.keycloak.org/server/all-config

How to build locally a development Docker image

Navigate into one of the version folders and run the following command

docker build -t ivanfranchin/keycloak-clustered:latest .

How to check if Keycloak instances are sharing user sessions

Open two different browsers, for instance Chrome and Safari or Chrome and Incognito Chrome.
In one access http://localhost:8080/admin/ and, in another, http://localhost:8081/admin/
Login with the following credentials
```
username: admin
password: admin
```
Once logged in

Click Sessions present on the menu on the left;
You should see that admin has two sessions.

Running a Keycloak Cluster using JDBC_PING in Virtual Machines

Prerequisites

VirtualBox and Vagrant

Startup

Open a terminal and make sure you are in keycloak-clustered root folder

You can edit Vagrantfile and set the database and/or the discovery protocol to be used

Start the virtual machines by running the command below

vagrant up

Mac Users

If you have an error like the one below

The IP address configured for the host-only network is not within the
allowed ranges. Please update the address used to be within the allowed
ranges and run the command again.

  Address: 10.0.0.1
  Ranges: 123.456.78.0/21

Valid ranges can be modified in the /etc/vbox/networks.conf file. For
more information including valid format see:

  https://www.virtualbox.org/manual/ch06.html#network_hostonly

Create a new file at /etc/vbox/networks.conf on your Mac with content

* 10.0.0.0/8 123.456.78.0/21
* 2001::/64

Wait a bit until the virtual machines get started. It will take some time.

Once the execution of the command vagrant up finishes, we can check the state of all active Vagrant environments

vagrant status

Check keycloak-clustered docker logs in keycloak1 virtual machine

vagrant ssh keycloak1
vagrant@vagrant:~$ docker logs keycloak-clustered -f

Note: To get out of the logging view press Ctrl+C and to exit the virtual machine type exit

Check keycloak-clustered docker logs in keycloak2 virtual machine

vagrant ssh keycloak2
vagrant@vagrant:~$ docker logs keycloak-clustered -f

Note: To get out of the logging view press Ctrl+C and to exit the virtual machine type exit

Check databases if you are using JDBC_PING

vagrant ssh databases

Note: To exit the virtual machine type exit

MySQL

vagrant@vagrant:~$ docker exec -it -e MYSQL_PWD=password mysql mysql -ukeycloak --database keycloak
mysql> show tables;
mysql> SELECT * FROM JGROUPSPING;

Note: To exit type exit

MariaDB

vagrant@vagrant:~$ docker exec -it mariadb mysql -ukeycloak -ppassword --database keycloak
MariaDB [keycloak]> show tables;
MariaDB [keycloak]> SELECT * FROM JGROUPSPING;

Note: To exit type exit

Postgres

vagrant@vagrant:~$ docker exec -it postgres psql -U keycloak
keycloak=# \dt *.*
  
-- `public` schema
keycloak=# SELECT * FROM JGROUPSPING;
  
-- in case the schema `myschema` was set
keycloak=# SELECT * FROM myschema.JGROUPSPING;

Note: To exit type \q

Testing

In order to test it, have a look at How to check if keycloak-clustered instances are sharing user sessions

Using another database

Edit Vagrantfile by setting to DB_VENDOR variable the database to be used

Reload Keycloak virtual machines by running

vagrant reload keycloak1 keycloak2 --provision

Teardown

Suspend the machines

Suspending the virtual machines will stop them and save their current running state. For it run

vagrant suspend

To bring the virtual machines back up run

vagrant up

Halt the machines

Halting the virtual machines will gracefully shut down the guest operating system and power down the guest machine

vagrant halt

It preserves the contents of disk and allows to start it again by running

vagrant up

Destroy the machines

Destroying the virtual machine will remove all traces of the guest machine from your system. It'll stop the guest machine, power it down, and reclaim its disk space and RAM.

vagrant destroy -f

For a complete clean up, you can remove Vagrant box used in this section

vagrant box remove hashicorp/bionic64
