Push changes between several local git repos - lifuzu/cafe GitHub Wiki

1. Install openssh client and server on each image:

sudo apt-get install openssh-client
sudo apt-get install openssh-server

2. Copy public ssh key to your "server" image:

ssh-copy-id <user>@[host|ip]

3. Clone the repo from your "server" image:

git clone <user>@[host|ip]:/path/to/the/repo

4. If you want to push the change to your "server" image, you need to config (on your 'server' image side):

git config receive.denyCurrentBranch ignore

5. Then you can set back the config (on your 'server' image side):

git config receive.denyCurrentBranch refuse
