Hey, I'm using Flink Operator 1.3.0 on kubernetes. And Taskmanagers of my job have a dependency on a sidecar that should start in 2-3 mins. Problem is that task managers instantly contact jobmanager and if it's healthy it tries to start a Job. But sidecar of jobmanager is still not ready yet (according to readiness health checks). Can I delay start-up of a job or respect kubernetes readiness health checks somehow?
