Re: K3s – Lightweight Kubernetes

This is extremely welcome. Kube needs to glom on to all available architectures to fulfill its destiny, to some extent, and the memory/cpu usage of kubeapi et al. can be prohibitive for small setups. Having to revert to ansible/systemd in "some cases" really weakens the story of a universal datacenter O/S.

My hope is for more competition for development k8s (or k3s!) - minikube and docker-for-desktop is plagued with high CPU usage problems, and OSX-wielding developers are still doubtful. It will require a lot of work and elbow grease to convince them. I've built a hosted platform that tries to address this, but it's a complex education problem, which I am not well suited to solve :(

Looks quite interesting for small setups, curious to read more about the limitations (E.g. "Added sqlite3 as the default storage mechanism. etcd3 is still available, but not the default." - what availability promises can this make?)

Do you think kubernetes are necessary for small businesses?

No, for the same reason that Martin Fowler argues you should start with a monolith first before moving to a microservices architecture.

What is currently a good alternative for a small business who needs to distribute containers on a handful of nodes? Docker swarm mode?

If you need to distribute containers on a handful of nodes, kubernetes is great (and far better than Docker swarm imho). However, most small businesses probably don't need to have a microservice setup and can simply deploy a simple monolith while they focus on getting their business off the ground.
