I learn from you that the solution is enabling sticky-sessions using cookies to ingress controller (K8s nginx). This would ensure that all requests from a given user are directed to the same instance over a configurable period of time.
It's a good solution and resolve the login cookpit.
But i've a important question:
into my architecture there are:
1 microservices camunda with 2 POD Others microservices that call api rest camunda fecthAndLock. if i enable sticky-sessions, lose the benefit of scaling pod? All requests from a microservice A to Camunda user are directed to the same POD?
