Change Kops deployment style

1
votes

I deployed a cluster of Kubernetes on AWS through the use of Kops. Like all those who have used Kops know, Kops places constraints in building a Kubernetes on AWS infrastructure (for example, when it goes to perform a multi-master installation what it does is create in each AZ of a region an AWS autoscaling group with a single instance EC2).

My question is: is it possible to change the way in which it carries out the deployment?

Specifically, I would like a deployment with 3 Masters in each AZ, so that the number of Masters is 9.

Suggestions? Thank you.

kops create cluster ... should be able to spread the masters in different zones depending on the number. You need these two options when creating a cluster

--master-count int32               Set the number of masters.  Defaults to one master per master-zone
--master-zones strings             Zones in which to run masters (must be an odd number)

So in other words for example for 9 masters in 3 zones:

--master-count 9
--master-zones us-east-1d,us-east-1b,us-east-1c

More info in the CLI options.
