Keycloak 26.x exposes dedicated health endpoints on the management port (9000) via /health/live and /health/ready. The previous probes used GET / on port 8080 which redirects to the configured KC_HOSTNAME (HTTPS), causing kubelet to fail the probe with "Probe terminated redirects" and eventually kill the pod in a crashloop. Changes: - Add KC_HEALTH_ENABLED=true to activate health endpoints - Expose management port 9000 in container ports - Switch liveness probe to /health/live on port 9000 - Switch readiness probe to /health/ready on port 9000 - Increase failure thresholds for more tolerance during startup Co-Authored-By: Claude Opus 4.6 <[email protected]> Signed-off-by: mattia-eleuteri <[email protected]> (cherry picked from commit 0873691)
Use a startupProbe to defer liveness/readiness checks until Keycloak has fully started, instead of relying on initialDelaySeconds. This is more robust for applications with variable startup times.
