learning k8s with minikube

start clean

    #minikube delete --all
    minikube start --driver=docker --container-runtime=containerd --nodes 3

docker ps
    minikube status

    kubectl get nodes -o wide
kubectl label nodes minikube kubernetes.io/role=master
kubectl label nodes minikube-m02 kubernetes.io/role=worker
kubectl label nodes minikube-m03 kubernetes.io/role=worker

–either– eventually enable ingress using the plugin

    minikube addons enable ingress

–or– go for the full-blown thing

and make every node elegible

#kubectl get nodes --show-labels
kubectl describe node minikube | sed -n '/^Labels:/,/^Annotations:/p' | sed '$d'
kubectl describe node minikube-m02 | sed -n '/^Labels:/,/^Annotations:/p' | sed '$d'
kubectl label nodes minikube-m02 minikube.k8s.io/primary=true

    kubectl get pods -n ingress-nginx -o wide
    kubectl scale deploy -n ingress-nginx ingress-nginx-controller --replicas=2

moar options

    #minikube addons enable metrics-server

additional nodes

kind

    kubectl label nodes minikube ingress-ready=true
    kubectl label nodes minikube-m02 ingress-ready=true
