Developed and delivered a container PID 1 safety warning feature for the keycloak/keycloak repository, addressing graceful shutdown reliability in containerized environments. The work involved migrating container-detection logic from shell scripting to Java, enhancing robustness and reducing dependency on runtime command detection. Startup scripts and distribution content were updated to clearly surface guidance for operators, ensuring users are alerted when Keycloak is not running as PID 1 with KC_RUN_IN_CONTAINER enabled. This solution improved deployment reliability and user experience for container operators. The project required collaboration across contributors and demonstrated proficiency in Java, containerization, shell scripting, and testing within production workflows.
