In the AMQ Broker 7.10 operator it's possible to configure the liveness and readiness probes in the ActiveMQArtemis CR. This is very helpful. It would be even better when also the startup probe could be configured in the ActiveMQArtemis CR to allow, for example, a longer startup time for a broker pod.
