Docker scale - auto-failure configuration in docker

Hi team, I have some doubts regarding docker scaling,
I have a java based container. Its should be processed and give responses to so many curl request from another point.
So we scaled it to 2 using docker scaling. So I have 2 doubts

  1. is the requests are hitting by the round-robin method?
  2. if one instance is down then it will automatically redirect to another one?
  3. if we are not getting a response after the 30s then redirect to the second instance ? is there any configuration to set this?
