I. Introduction
In this blog, we will create a docker-compose file that will run a Keycloak and MySQL instance as a docker container. Keycloak will connect to the MySQL database using JDBC.
II. Prerequisites
Docker must be running on your local machine.
III. What should be inside the project?
- The docker compose file
- keycloak/import-realm.json — This realm will imported into Keycloak once a new instance is created. This file is use in the exercise available at https://github.com/czetsuya/keycloak-angular-auth/blob/master/config/keycloak-auth-realm.json.
