A typical command to create an EC2 key pair is as follows:
aws ec2 create-key-pair --key-name kubernetes-coreos --query 'KeyMaterial' --output text >
kubernetes-coreos.pem
chmod 400 kubernetes-coreos.pem
The command to create a KMS key is as follows:
aws kms --region=us-east-1 create-key --description="kube-aws assets"
Copy the KeyMetadata.Arn string and use it to initialize a CloudFormation stack. For example, a cluster
called kubernetes-coreos-cluster-1 with the asset directory as kube-coreos-cluster-1 is initialized as follows:
mkdir kube-coreos-cluster-1
cd kube-coreos-cluster-1
kube-aws init --cluster-name=kubernetes-coreos-cluster-1 --external-dns-name=ORAMAGSEARCH.
COM --region=us-east-1 --availability-zone=us-east-1c --key-name=kubernetes-coreos --kmskey-arn="arn:aws:kms:us-east-1:xxxxxxxxxx:key/xxxxxxxxxxxxxxxxxxx"
The commands to render the contents of an assets directory, validate a CloudFormation stack, and
launch a CloudFormation stack are as follows:
kube-aws render
kube-aws validate
kube-aws up
Next, launch into the controller instance for each of the Kubernetes clusters. The Public IP of a
controller may be obtained from the EC2 Console as shown in Figure 16-2.
