Hey everyone, hope all are safe and well.
I wanted to throw out the general question ‘Do you think it’s appropriate to use a single node stack in prod?’
microk8s/minikube/minishift all provide good standalone dev clusters for ci/cd but there are scenarios where in prod sometimes I don’t need a full blown cluster.
Other than bug fixes/delays in receiving upstream patches are there any major gotcha’s if I was to do this ?
My main hesitation would be that they haven’t been designed with prod in mind.
This means it’s likely they are less reliable.
Then there’s the performance overhead of running everything on a single node.
All thoughts/opinions either way are welcome.
Cheers,
Nate
Don’t take advice about running in production from me as I haven’t managed production workloads! 
But I have wondered about the same question.
My thought is if you are going to run an application on a single node anyway (that may be a separate discussion), then why not go with single node K8s and make use of the tooling.
While minikube is definitely more for testing, I think microk8s is designed for production, at least according its website.
Kind regards,
Stephen
You’re completely spot on.
Somehow I missed this completely: “MicroK8s is a powerful, lightweight, reliable production-ready Kubernetes distribution.”
Cheers dude!
Is this an edge computing idea? If so, have you taken a look at kubeedge it’s another CNCF project with that use-case in mind and is intended for single-node type deployments.
