Add support for Instance Refresh for EC2 Auto Scaling

[stevehipwell]

Can the AWS Node Termination Handler handle the events triggered by Instance Refresh for EC2 Auto Scaling to provide a seamless worker upgrade path? If not is this something that could be supported?

It's not possible to add support for Instance Refresh with the current daemonset implementation. We are tracking this issue #14 to support generic shutdown events by responding to ASG lifecycle hooks and events from EventBridge. But active development is not underway yet.

Hey everyone! 👋 We have listened to your request to expand the aws-node-termination-handler to include all EC2 instances and not just Spot.

We have pushed a branch to the repo queue-processor that allows aws-node-termination-handler to run as a deployment in your cluster and respond to EventBridge termination events from ASG, EC2, and Spot.

Check out the new README on that branch and let us know what you think

This new functionality is currently in Alpha, but we would love your feedback!

@bwagner5 Those links are 404s for me, has that branch been merged at this point?

[bwagner5]

@philomory Yes, the queue-processor branched is merged into main now.

It was first released in https://github.com/aws/aws-node-termination-handler/releases/tag/v1.9.0

I'd recommend using the latest release, https://github.com/aws/aws-node-termination-handler/releases/tag/v1.11.0 to try it out

So, should this issue be closed?
