vagrantkind

vagrant machine installing docker, kubectrl, istioctl, helm and kind to run a simple local kubernetes cluster

simple path without istio, but with calico and ingress

• see: https://github.com/wlanboy/vagrantkind/blob/main/arm64-steps.md

gists for WSL

• https://gist.github.com/wlanboy/steps.sh
• https://gist.github.com/wlanboy/metallb-pool.yaml
• https://gist.github.com/wlanboy/metallb-adv.yaml

create vm

• vagrant up

ssh into vm

• vagrant ssh

create kind kubernetes cluster

• kind create cluster

or create kind cluster with config for all services (calico + istio)

• sh setup-kind.sh
• see: https://github.com/wlanboy/vagrantkind/blob/main/setup-kind.sh

destroy kind kubernetes cluster

• kind delete cluster
• or kind delete clusters kindcluster

example log for cluster creation

vagrant@kind:~$ kind create cluster
Creating cluster "kind" ...
 ✓ Ensuring node image (kindest/node:v1.21.1) 🖼
 ✓ Preparing nodes 📦
 ✓ Writing configuration 📜
 ✓ Starting control-plane 🕹️
 ✓ Installing CNI 🔌
 ✓ Installing StorageClass 💾
Set kubectl context to "kind-kind"
You can now use your cluster with:

kubectl cluster-info --context kind-kind

get basic cluster information

• kubectl cluster-info --context kind-kind

vagrant@kind:~$ kubectl cluster-info --context kind-kind
Kubernetes control plane is running at https://127.0.0.1:40239
CoreDNS is running at https://127.0.0.1:40239/api/v1/namespaces/kube-system/services/kube-dns:dns/proxy

To further debug and diagnose cluster problems, use 'kubectl cluster-info dump'.

• kubectl get nodes

vagrant@kind:~$ kubectl get nodes
