    > gcloud components install kubectl

    1/ Configure Google Cloud account:
    > gcloud config set account YOUR_EMAIL_ADDRESS
    > gcloud config set project YOUR_PROJECT_ID
    > gcloud config set compute/zone us-west1-a
    > gcloud config set container/cluster example
    > gcloud container clusters get-credentials example

    2/ Create cluster on Google Cloud Console:
    > gcloud container clusters create example --machine-type=f1-micro --num-nodes=3 --scopes=cloud-platform --zone=us-west1-a

    3/ Create a static IP for Ingress:
    > gcloud compute addresses create example-ingress-ip --global

    4/ Create persistant disk for database:
    > gcloud compute disks create --size 200GB example-disk

    5/ Create configmap:
    > kubectl create configmap example-config -f kubernetes-config-map.yaml

    6/ Create deployments:
    > kubectl create -f kubernetes.yaml

    7/ Create database:

    > kubectl delete -f kubernetes-config-map.yaml
    > kubectl delete -f kubernetes.yaml
    > gcloud container clusters delete example
    > gcloud compute disks delete example-disk
    > gcloud compute addresses delete example-ingress-ip
