ssh support

[moshir]

Hi,

i've been trying to use lambda-git and it's been working great locally.
When using it in lambda, as i'm using ssh keys, the lambda fails with

Could not create directory '/home/sbx_user1051/.ssh'.\r\nFailed to add the host to the list of known hosts (/home/sbx_user1051/.ssh/known_hosts)

The id_rsa file is saved before the git command is issued in the /tmp/ folder.

The problem could be reproduced as follows , assuming the lambda has been packaged including lambda-git:

import git 
import os
env={
    "GIT_SSH_COMMAND": "ssh -i {} -o StrictHostKeyChecking=no".format("/tmp/id_rsa"),
    "HOME" : "/tmp/me"
}
def handler(event):
    git.exec_command('checkout', repo, "master", cwd="/tmp/repositories/",env=env)

which runs fine locally, but results in the exception mentionned above when run in lambda.

Environment

• aws lambda
• runtime : python 2.7
• virtualenv

Hi moshir,

I came across this searching for answers, and I found them! So I thought I'd help you with your issue if you're still facing it. Rather than attempting to write to known hosts file at all, just pass it /dev/null. That way the write will succeed... to nowhere.

"GIT_SSH_COMMAND": "ssh -i {} -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null".format("/tmp/id_rsa"),
