10/10/2022, 12:12 PMhello guys, i have an app deployed in k8s with 2 replicas, the problem is each time i increase the number of replicas, the new replica is directly marked as available and operating. but the real thing that is happening that at the startup it builds a model that takes about 5 mins. for this issue i want the traffic to be routed to the first replica that has been operating for long time, and once the new replica builds the model, then i need to make it receive traffic as well. any idea how to do that?

10/10/2022, 12:25 PMNo worries, I assume there's some kind of check/service you can probe to determine if it's ready to accept traffic?
https://kubernetes.io/docs/tasks/configure-pod-container/configure-liveness-readiness-startup-probes/#define-readiness-probes is particularly relevant for you use case I think

10/10/2022, 12:30 PMyeah sure
am using a startup probe with initial delay 1000 seconds. testing it
it didnt work as it seemed that the first request to the application builds the model, nothing happens at the startup...
ill ask the dev to run the build model request at startup
