Requirement 1 (routes): I need to be able to route to "n" independent Kubernetes deployments. Such as:

1. http://building-1-building
2. http://building-2-building
3. http://building-3-building
4. ... n ...

Each building is receiving traffic that is independent of the others.

Requirement 2 (independence): If pod for building-2-deployment dies, I would like only building-2-deployment to be restarted and the other n-1 deployments to be not affected.

Requirement 3 (kill then replace): If pod for building-2-deployment is unhealthy, I would like it to be killed then a new one created. Not a replacement created, then the sick is killed.

When I update the image and issue a "kubectl apply -f building.yaml", I would like each deployment to be shut down then a new one started with the new SW. In other words, not create a second then kill the first.

Requirement 4 (yaml): This application is created and updated with a yaml file so that it's repeatable and archivable.

• kubectl create -f building.yaml
• kubectl apply -f building.yaml

Partial Solution: The following yaml creates routes (requirement 1), operates each deployment independently (requirement 2), but fails on to kill before starting a replacement (requirement 3).

This partial solution is a little verbose as each deployment is replicated "n" time where only the "n" is changed.

I would appreciate a suggested to solve all 3 requirements.
