Una de las maneras más simples de relacionarse con Kubernetes es usar minikube para ejecutar comandos

Instalando minikube como cluster

curl -Lo minikube https://storage.googleapis.com/minikube/releases/v0.30.0/minikube-linux-amd64 && chmod +x minikube && sudo cp minikube /usr/local/bin/ && rm minikube

Iniciando minikube

minikube start

Ejecutando la primer aplicacion sin estado (stateless) TASKS

minikube start

ls ~/.kube

cat ~/.kube/config

kubectl describe nodes minikube

kubectl apply -f https://k8s.io/examples/application/deployment.yaml

kubectl get pods

kubectl describe deployment nginx-deployment

kubectl describe pod nginx-deployment-*

kubectl apply -f https://k8s.io/examples/application/deployment-update.yaml;kubectl get pods --watch

kubectl apply -f https://k8s.io/examples/application/deployment-scale.yaml;kubectl get pods --watch

kubectl delete deployment nginx-deployment;kubectl get pods --watch

minikube delete

Ejecutando una aplicación con estado (statefull)

minikube start

minikube dashboard

kubectl get pv

kubectl create -f https://k8s.io/examples/application/mysql/mysql-pv.yaml

minikube ssh
ls /mnt

kubectl create -f https://k8s.io/examples/application/mysql/mysql-deployment.yaml

minikube ssh
ls /mnt
