Deploy Kubernetes on AWS Reserved instances

I'm very new to KOPS, so I have very questions about the cluster deployment process in AWS.

Supose I have 3 reserved instances: I want to deploy one Master and two workers in my existing AWS reserved instances.

Can anyone write a step by step guide to acomplsih that?

Thanks.

Solution

When creating the cluster you must specify the node and master types to match those of the reserved instances, using the arguments --master-size and --node-size. For example if you have reserved m4.large instances just set --master-size=m4.large.

If the instance type you're using is the same as the reserved one, AWS will apply the discount automatically.
