This is a docker container which contains a perl script to pull a user's SSH keys from Github and add them to the user's ssh authorized keys file.
This will overwrite the authorized keys file, so it is only appropriate for a case where only the keys uploaded to Github should be able to log in.
Specify the github user keys to pull using an environment variable to docker run or docker-compose, like:
# with docker run:
docker run \
-v ~/.ssh:/perl/.ssh \
-e GITHUB_USER=jasongwartz \
jasongwartz/github-authorized-keys-docker
# or with docker-compose
GITHUB_USER=jasongwartz docker-compose up -d`
