 1 | git-ssh-server
 2 | =================
 3 | 
 4 | A minimal GIT server.
 5 | 
 6 | Build instructions
 7 | ==================
 8 | 
 9 |     git clone https://github.com/unixtastic/git-ssh-server
10 |     docker build -t 'unixtastic/git-ssh-server' .
11 | 
12 | Usage instructions
13 | ==================
14 | 
15 | To run this first create a data directory on your docker host to hold git data, ssh authentication,
16 | and possibly git-shell-commands.
17 | 
18 |     mkdir /docker_data/git
19 | 
20 | Run the container.
21 | 
22 |     docker run -d -p 2222:22 -v /docker_data/git:/git unixtastic/git-ssh-server
23 | 
24 | You may substitute '2222' with any port number of your choosing.
25 | 
26 | Add users
27 | ---------
28 | 
29 | Setup SSH:
30 | 
31 |     cd /docker_data/git
32 |     mkdir .ssh
33 |     chown -R 987:987 .ssh
34 |     chmod -R 700 .ssh
35 |     touch .ssh/authorized_keys
36 |     chmod 600 .ssh/authorized_keys
37 | 
38 | Add user public keys to `.ssh/authorized_keys` just like you would do for 'normal' SSH.
39 | 
40 |     touch /docker_data/git/.hushlogin to prevent login banners that can confuse git.
41 | 
42 | Setup repos
43 | -----------
44 | 
45 |     mkdir /docker_data/git/mynewproject.git
46 |     cd /docker_data/git/mynewproject.git
47 |     git --bare init
48 |     chown -R 987:987 .
49 | 
50 | Clone the repo from a client:
51 | 
52 |     git clone ssh://git@myserver:2222/git/mynewproject.git
53 | 
54 | Setup git-shell-commands
55 | ------------------------
56 | 
57 |     mkdir /docker_data/git/git-shell-commands
58 |     chown 987:987 /docker_data/git/git-shell-commands
59 |     chmod 700 /docker_data/git/git-shell-commands
60 | 
61 | Add your commands to the above directory. You might want to start with list, which
62 | you can find under `/usr/share/doc` on most git client machines.
63 | 
64 | Notes
65 | =====
66 | 
67 | The SSH host keys are generated at the first run of each new container. This will confuse some git clients and really should be changed.
