publicKey option not working.

[mohanramanujam]

Hi

The connection closes immediately

command invoked:
docker run --rm -p 2222:22 -v /var/run/docker.sock:/var/run/docker.sock -v ./authorized_keys:/authorized_keys --name sshd-python-docker -e FILTERS={"name":["^/python-docker$"]} -e AUTH_MECHANISM=publicKey -e AUTHORIZED_KEYS=/authorized_keys jeroenpeeters/docker-ssh

I have tested NoAuth, multiUser, etc. and they all work fine but publicKey is not working

here is error log:
warn: --minUptime not set. Defaulting to: 1000ms

It seems that ./authorized_keys is a directory while it should be a file containing one key per line.
