I have recently setup a Rancher cluster on AWS using RancherOS as it’s nodes. Right now I manually created all these from the provided AMIs, upgraded them and manually joined them.
On the Add Host screen, I see AWS is an option, but if I read it correctly, it defaults to ubuntu machines. I see I can select another AMI, so I could launch RancherOS ones, but how would I provide the user-data to it to launch with?
