host verification failed with git deployment

[noogen]

I'm getting "host verification failed" error when using git deployment. After some troubleshooting, it turn out to be an issue with the known_hosts file not recognizing the dokku container host. Just wondering the best way fix this. Right now, I modified /etc/ssh/ssh_config with the following add to the Dockerfile:

RUN sed -i "s/# StrictHostKeyChecking ask\n StrictHostKeyChecking no/g" /etc/ssh/ssh_config

That's probably is the good way to solve it.

I'm having problems with the fix introduced here using a fresh install of dokku-alt on Ubuntu 14.04.

I changed it to RUN sed -i "s/# StrictHostKeyChecking ask/ StrictHostKeyChecking no/g" /etc/ssh/ssh_config and it appeared to work
