Scenario:
- I got 3 replicas of a service running
- I want to update its version
This is whats happening:
- The new container will be created
- As soon the container are switching their status from ContainerCreation to Running kubernetes will start terminating old versions of this container.
Problem: Status Running does not make sure the application is available. How can I prevent kubernetes from terminating services before it is not sure the containers application is available? Maybe adding a necessary health check?
