I followed the Link Amazon Web Services to Docker Cloud article step-by-step and successfully generated a role ARN, but when I enter the ARN to link my docker cloud account, I'm getting the following error message
Invalid AWS role or insufficient permissions
I'm not sure if the error is caused by one of these prerequisites
Note: Your AWS account must support EC2-VPC to deploy swarms, and you must also have an SSH key in each AWS region you deploy swarms in.
How do I check if my AWS account support EC2-VCP and how do I know which AWS region I'm deploying swarms in?
