ap-northeast-2 seoul region support

[statkclee]

I've got the following error such that I've looked at the code and found out no seoul region.
When are you going to support seoul region?

spark-ec2 depends on custom AMIs which are rarely updated. I doubt support for the Seoul region will be added anytime soon, but I would love to be proven wrong about that.

If you are interested in trying a similar tool to spark-ec2 that just depends on the default Amazon Linux AMI, I recommend my project, Flintrock. It should work with Amazon Linux in any region out of the box.

Unfortunately given the other commitments I have I am not sure when the AMIs will be updated. Meanwhile I wholeheartedly recommend checking out Flintrock for newer regions.

I see... Thank you for recommendations.

Could you please include eu-west-2 to your supported regions?
Thanks!
