> [k3s|https://github.com/k3s-io/k3s] is a lightweight and has fully conformant production-ready Kubernetes distribution.
> k3s kube config use a different encryption algorithm which not same with Kubernetes config, and kubernetes-client also doesn't infer kube config encryption algorithm until 5.10.0 version.
> kubernetes-client fixes k3s kube config compatibility through [issue|https://github.com/fabric8io/kubernetes-client/issues/3535] and works from 5.10.0 version.
> flink-kubernetes module now uses 5.5.0 version and submitting to k3s would fail
