kind-bootstrap

Local Kubernetes bootstrap for coding challenges, using kind.

It spins up a cluster with:

• 1 master and 2 workers with different containerd and kubelet versions (1.17, 1.18)
• one of the worker nodes has a "/sensitive" filesystem mount
• worker nodes also support the runsc runtime (gVisor)

Setup

Install Docker + kind and run:

$ git clone https://github.com/MarshallWace/kind-bootstrap.git
$ cd kind-bootstrap/

$ ./kind-with-local-registry.sh

kubectl cluster-info --context kind-mw


$ kubectl get nodes --context kind-mw
