Create CoreOS VM on AWS with Docker Machine
Raw
coreos-aws-docker-machine.md

This is slightly trickier than I anticipated so noting it down for future reference.

The command should be along these lines (assuming AWS keys are configured via environment variables or config file):

$ docker-machine create \
  -d amazonec2 \
  --amazonec2-region us-west-1 \
  --amazonec2-ami ami-818bd5e1 \
  --amazonec2-zone b \
  --amazonec2-ssh-user core \
  --amazonec2-device-name "/dev/xvda" \
  coreosvm

Since CoreOS SSH user is core you must specify that. Likewise, the root device is not /dev/sda as usual but rather /dev/xvda so you must be specific about this. You can get the AMIs from CoreOS website.
