Launching the CloudFormation
Chapter 4 ■ Using Multiple Zones
After we modify cluster.yaml, the CloudFormation stack must be validated. Validate the CloudFormation
stack with the following command:
kube-aws validate
Launch the CloudFormation stack.
kube-aws up
The AWS resources, such as the EC2 instances, scaling groups, and launch configurations are created,
and the CloudFormation is launched as shown in Figure 4-11.
Figure 4-11. Launching the CloudFormation
The status of the CloudFormation may be found with the following command:
kube-aws status
The controller IP is listed, as shown in Figure 4-12.
Figure 4-12. Finding the status of CloudFormation
The EC2 instances launched by the CloudFormation stack are shown in Figure 4-13. As indicated in the
Availability Zone column, two instances each are launched in the us-east-1b, us-east-1c, and us-east-1d
zones. The single controller runs in zone us-east-1b.
