Kops: Support of AWS a1.* instances (Arm-based)

[styk-tv]

With the a1.* instances being significantly cheaper, would it make sense at support of a1.* aws instances?

Type Spec:
https://aws.amazon.com/ec2/instance-types/a1/

This is closed, did this actually happen? Is it inherently there already?

It looks like it is in master so we need to wait for a release or do a build yourself.

Just because it was added to the list of instance types that exist doesn't mean anything will work on it. Probably you need an OS image specifically built for ARM and all your docker containers will have to have ARM images.

It does not work! cloud-init script fails due to exec error. I tried using arm based ubuntu ami.

That binary is for x86-64. You need to acquire or build one for arm64 and then modify things to pull that. I would start by sorting out what process in the project is building that binary and then submitting a PR modifying that to build for both x86-64 + aarch64.

M6g, C6g, and R6g have been announced and looks like the performance and value are great.

I will start experimenting with ARM support for Kops. Worker nodes should be pretty easy to configure.
