Thanks! I think for our scenario it's a bit overkill as we're only running one container and pm2 seems a better fit for that.

It would be interesting to know how this works under the hood though, is this just built on top of docker swarm load balancing?

Kubernetes will definitely be an overkill if you run only one container. But, if your application follows microservice architecture and have multiple containers, Kubernetes is the best solution to run them.

Kubernetes architecture is entirely different from that of Docker Swarm.

A Kubernetes Service object [1] can load balance traffic to various Kubernetes Pods (think containers) [2] as defined by it's " pod selectors". It can choose to direct traffic only to running containers.
