Chapter 2 ■ Kubernetes on CoreOS on AWS
Figure 2-3. Validate the tarball’s GPG signature
Extract the binary from the tar.gz file:
tar zxvf kube-aws-linux-amd64.tar.gz
Add kube-aws to the path:
sudo mv linux-amd64/kube-aws /usr/local/bin
The kube-aws CloudFormation generator is installed. You can display information about its usage with
the kube-aws –help command.
Setting Up Cluster Parameters
Before initializing and launching the AWS CloudFormation cluster we need to create or define the following
cluster parameters:
• EC2 key pair
• KMS key
• External DNS name
Before creating a key pair we need to configure an AWS region; we already did that with the aws
configure command. Run the following command to create a key pair called kubernetes-coreos and save it
as kubernetes-coreos.pem:
aws ec2 create-key-pair --key-name kubernetes-coreos --query 'KeyMaterial' --output text >
kubernetes-coreos.pem
Modify the access permissions of the key pair using the mode 400, which sets access permissions to
read by owner.
chmod 400 kubernetes-coreos.pem
