This script adds users and private keys to SFTP stacks as created by a cookbook like this one. The script asks you to choose an AWS OpsWorks stack that implements the SFTP cookbook. Then it allows you to create users (a password will be generated), or add public keys to existing users. Once you're through making changes, the script lists the changes made and asks if you'd like to update the stack now:

Make more changes? [y/N]

3. Created user schwantzin - xnek5tOiywMd

Update stack now? [Y/n]

If you select yes, the script updates your stack JSON and runs Setup on the stack.

This app connects to AWS via boto. That means it can gather your credentials from the ~/.aws/credentials file. The default profile is assumed unless you set AWS_PROFILE to a different profile name in your environment.
