Linking your Amazon Web Services account to Docker Cloud has a few more steps. To link the account, we need to provide Docker Cloud with the role Amazon Resource Names (ARNs), which has the necessary privileges to access the resources required within our Amazon Web Services account to be able to launch instances.
To do this, we must first create a policy. To do so, log in to your Amazon Web Services account at https://console.aws.amazon.com/ or your organization's custom sign-in page if you use one. Once logged in, go to the Services menu, which can be found in the top-left of the page, and find the IAM service.
