The article Deploy Keycloak single sign-on with Ansible discussed how to automate the deployment of Keycloak.
In this follow-up article, we'll use that as a baseline and explore how to automate the configuration of the Keycloak single sign-on server, including setting up users, specifying LDAP connection details, and so on.
Here again, to facilitate our automation, we will leverage an Ansible collection named middleware automation.
In the previous article, we saw in detail how to automate the installation of Keycloak.
Prior to running the playbook, we are going to enhance it even further to perform day two configurations of the Keycloak server, including the configuration of the SSO realm, clients, and users.
Configure Single Sign-On. The Ansible collection for Keycloak allows defining the realm, client, and users without adding a single, extra task.
All that is needed is to define a few extra variables.
Of course, those variables are quite structured and need to be formatted correctly for Ansible to be able to configure Keycloak appropriately.
Note that this example, purposely, does not rely on any external sources so that it can be used easily, to test the collection without requiring the setup of any extra resources.
Because the SSO configuration is quite dense, we are going to break down each portion to not only provide additional insight, but to illustrate its significance in the SSO configuration.
The very first step is to define a realm, which, for the purpose of this article, contains the desired user and role details, but other capabilities provided by Keycloak that will be explored throughout the article.
The next portion of the variables provided populates the realm with the appropriate details related to users and roles.
To go even further, we can add a check to our playbook that will use the Keycloak admin credentials to get a token from the SSO server.
This emulates what will happen when a user tries to access an application using the SSO service.
On top of deploying the Keycloak server, we have fully automated the configuration of our SSO. We can deploy a fully functional instance, in any environment, without any manual intervention.
Most importantly, it is accomplished in a secure and repeatable fashion.
With just this playbook, you can set up the entire infrastructure for SSO in a matter of minutes using the tooling provided by the Ansible Middleware project.
