AWS Container Day - Customizing Managed Node Groups

Managed Node Groups provide for automated provisioning and lifecycle management of nodes within Amazon EKS clusters. This means the responsibility of instance provisioning and node upgrade tasks falls on EKS. While this feature solves a number of problems, until now it has been limited regarding configuration options and customizations for your nodes.

In this session, we'll demonstrate the use of Launch Templates and Custom AMIs for Managed Node Groups. Launch templates provide a declarative method for specifying EC2 instance configuration, including user data and base environment modifications. For deeper customization requirements, custom AMIs are now supported as well, establishing a full range of customization options for use with managed node groups.

Great session. I have a question here, let's say I have an AWS EKS cluster provisioned with the launch configuration with instance type as t3.medium (for example) then can I create a new version of Launch Template with a new instance type as c5.xlarge to create new managed node groups in the same cluster? If yes then will my existing pods will get drained to new node group from older one automatically as well?

EKS makes me dumb. Worst kubernetes distro ever.

hmm not to be picky but if you run a tutorial for something you do not say: "...we have to create, actually I have created it already..." etc etc... As this is the point where most of people who does not know eks will stop watching.
