KIND during production

[Ahmet Temiz]

I just want know why I have to abandon KIND during production.

We strongly discourage using KIND in production because it isn't designed for or supported as such.

These priorities drive the design and development focus: https://kind.sigs.k8s.io/docs/contributing/project-scope/

For example:

- There's no supported way to maintain patching and upgrades

- The technology fundamentally lacks things like functioning OOM metrics / various things related to resource restriction at the moment

- As a upstream minimal distro, no additional opinionated security configuration is implemented

KIND clusters are designed to be cheap (relatively), ephemeral, and relatively "standard".

They are not built to span multiple physical machines or as permanent long-lived clusters.

If you'd like to bootstrap a production-grade cluster, please see: 

- https://github.com/kubernetes/kops

- https://kubernetes.io/docs/setup/production-environment/tools/kubeadm/create-cluster-kubeadm/ (kind uses kubeadm internally, but there's more to using kubeadm directly for serious non-ephemeral clusters)

- https://cluster-api.sigs.k8s.io/

- https://github.com/kubernetes-sigs/kubespray

Which are all part of the Kubernetes project under SIG Cluster Lifecycle.

Note: "using in production" here means serving long-lived production workloads.

KIND is suitable for example:
- developing Kubernetes itself
- Testing application or Kubernetes changes in CI
- Local Kubernetes application development

- bootstrapping Cluster API

Which are all documented use-cases.

Thank you..

you said " We strongly discourage using KIND in production because it isn't designed for or supported as such."

(pitty!. It seems to be working well and faster with my apps.)
