Win!!

17. $ … (前略) …
$ magnum bay-create —name k8s-cluster —baymodel k8smodel
$ gcloud container clusters create k8s-cluster
$ kubectl create -f nginx.yml

18. $ openssl genrsa -out client.key 4096
$ gcloud container clusters create k8s-cluster
$ kubectl create -f nginx.yml

19. $ cat > client.conf << END
[req]
distinguished_name = req_distinguished_name
req_extensions = req_ext
prompt = no
[req_distinguished_name]
CN = Your Name
[req_ext]
extendedKeyUsage = clientAuth
END
$ gcloud container clusters create k8s-cluster
$ kubectl create -f nginx.yml

20. $ openssl req -new -days 365
-config client.conf
-key client.key
-out client.csr
$ magnum ca-sign --bay k8s-cluster --csr client.csr > client.crt
$ magnum ca-show --bay k8s-cluster > ca.crt
$ gcloud container clusters create k8s-cluster
$ kubectl create -f nginx.yml

21. $ kubectl config set-cluster k8sbay
—server=${KUBERNETES_URL}
--certificate-authority=$(pwd)/ca.crt
$ kubectl config set-credentials client
—certificate-authority=$(pwd)/ca.crt
--client-key=$(pwd)/client.key
—client-certificate=$(pwd)/client.crt
$ kubectl config set-context k8sbay
—cluster=k8sbay --user=client
$ kubectl config use-context k8sbay
$ gcloud container clusters create k8s-cluster
$ kubectl create -f nginx.yml

22. $ … (前略) …
$ magnum bay-create —name k8s-cluster —baymodel k8smodel
$ … (中略) …
$ kubectl create -f nginx.yml
$ gcloud container clusters create k8s-cluster

$ … (中略) …
$ kubectl create -f nginx.yml
$ gcloud container clusters create k8s-cluster

チョット面倒な手順があるけど、
余計な部分を省けばトッテモ似てる！
