Can you change an application without changing any code in Kubernetes?
— Daniele Polencic (@danielepolencic) March 1, 2021
You can when you use multiple containers in a single Pod.

— Daniele Polencic (@danielepolencic) July 27, 2021
After talking to Chris the scope was adjusted a bit and the tool does just one thing (hopefully well).

-THREAD: How does the scheduler work in Kubernetes?
— Daniele Polencic (@danielepolencic) September 24, 2020
The scheduler is in charge of deciding where your pods are deployed in the cluster.
It might sound like an easy job, but it's rather complicated!
