Simple set of bash scripts for uploading public keys to remote servers via GitHub usernames
View authorized_keys.md

authorized_keys

A method for managing and giving team members access to remote servers without needing to pass around the master .pem key. Generates and sends authorized key files to a list of hosts based on a set of permissions.

fetch_keys_from_github.sh

Generates a new keys/*.txt file for each user defined in permissions.txt when one doesn't already exist. Gets the list by calling out to https://github.com/<user>.keys. After first fetching a set of keys, the list can be paired down if necessary before running upload_keys.sh.

./fetch_keys_from_github.sh
