# gitolite in pictures
|
||||
|
||||
Well, they say a picture speaks a thousand words, so here're a few!
|
||||
|
||||
**NOTE**: if you're viewing this file in raw text, please note that some
|
||||
characters in text within a ditaa drawing may not be ASCII. This is due to a
|
||||
ditaa flaw that treats even a single hyphen as a line drawing character, so I
|
||||
had to use Unicode 2010 for it. I expect that I will have to resort to
|
||||
similar tricks for colon, equals, and many others like it if and when I need
|
||||
those in text within a ditaa diagram.

### installation and setup
|
||||
|
||||
Here's a picture showing the "non-root" install. We assume Alice is the
|
||||
gitolite admin, and "git" is the hosting user on the server.

||||

|

The files names are there **only for information**. You do **not** have to do
|
||||
anything to them yourself; in fact you should not! You only need the command
|
||||
for each step shown:
|
||||
|
||||
1. copy the admin's pubkey to the server as "alice.pub"
|
||||
2. `git clone git://github.com/sitaramc/gitolite` or equivalent
|
||||
3. `gitolite/src/gl-system-install`
|
||||
4. `gl-setup alice.pub`
|
||||
|
||||
Note also that you only need ONE real user on the server. In our example it
|
||||
is git. In particular, you do NOT create Unix userids for your gitolite
|
||||
users.
|
||||

||||

|
||||
|
||||
### adding users to gitolite
|
||||
|
||||
Once you've done the install, here's how you add users.
|
||||
|
||||
.aa
|
||||
Adding users to gitolite
|
||||
------------------------------------------------------------------------
|
||||
|
||||
/-------------------\ /-----------------------\
|
||||
| user "git" | | user "alice" |
|
||||
| (on server) | | (on workstation) |
|
||||
| cGRE | | cPNK |
|
||||
\-------------------/ \-----------------------/
|
||||
/-------------------\ /-----------------------\
|
||||
| (gitolite) |----------->| ~/gitolite‐admin |
|
||||
| | (1) | |
|
||||
| | | |
|
||||
| |<-----------| |
|
||||
\-------------------/ (3) \-----------------------/
|
||||
|
||||
/-----------------------\
|
||||
/-------------------\ | (alice@workstation) |
|
||||
| bob cYEL |----\ |~/gitolite‐admin/keydir|
|
||||
| ~/.ssh/id_rsa.pub | | |cPNK |
|
||||
\-------------------/ | +-----------------------+
|
||||
\------>| bobby.pub |
|
||||
/-------------------\ (2) +-----------------------+
|
||||
| carol cYEL |----------->| carol.pub |
|
||||
| ~/.ssh/id_rsa.pub | +-----------------------+
|
||||
\-------------------/ | (...) |
|
||||
\-----------------------/
|
||||
|
||||
All this is done from the admin (Alice)'s workstation. The steps are:
|
||||
|
||||
1. `git clone git@server:gitolite-admin`
|
||||
2. obtain pubkeys from each user. Email, USB, DHL, pigeon post, owl mail,
|
||||
any method you like. Rename each received file to the name of the user,
|
||||
add a ".pub" at the end, copy it into `keydir/` in the gitolite-admin repo
|
||||
you cloned.
|
||||
3. `git add keydir`, then `git commit`, then `git push`
|
||||
|
||||
You do NOT need to add Carol or Bob as *real* (Unix) users. You do NOT add
|
||||
their keys directly anywhere on the server; you do it by cloning, adding keys,
|
||||
and pushing.
|
||||
|
||||
### adding repos to gitolite
|
||||
|
||||
Adding a repo is even easier. It's so easy that you don't really need a
|
||||
picture. OK maybe a small one:
|
||||
|
||||
.aa
|
||||
Adding repos to gitolite
|
||||
------------------------------------------------------------------------
|
||||
|
||||
/-------------------\ /-----------------------\
|
||||
| user "git" | | user "alice" |
|
||||
| (on server) | | (on workstation) |
|
||||
| cGRE | | cPNK |
|
||||
\-------------------/ \-----------------------/
|
||||
/-------------------\ /-----------------------\
|
||||
| (gitolite) |----------->| ~/gitolite‐admin |
|
||||
| | (1) | |
|
||||
| | | |
|
||||
| |<-----------| |
|
||||
\-------------------/ (3) \-----------------------/
|
||||
|
||||
/-----------------------------------\
|
||||
| (alice@workstation) |
|
||||
|~/gitolite‐admin/conf/gitolite.conf|
|
||||
| cPNK |
|
||||
+-----------------------------------+
|
||||
| <config lines for repo foo> |
|
||||
+-----------------------------------+
|
||||
| <config lines for repo bar> |
|
||||
+-----------------------------------+
|
||||
| (...) |
|
||||
\-----------------------------------/
|
||||
|
||||
Again, all this is done from the admin (Alice)'s workstation. Steps one and
|
||||
three are the same as for adding users, but step 2 consists of adding config
|
||||
lines for whatever repo you want too add.
|
||||
|
||||
1. `git clone git@server:gitolite-admin`
|
||||
2. edit `conf/gitolite.conf` in the repo clone you just made. Add repo
|
||||
paragraphs, maybe like this, and save the file:
|
||||
|
||||
repo foo
|
||||
RW+ = alice
|
||||
RW = bob
|
||||
|
||||
3. `git add conf/gitolite.conf`, then `git commit`, then `git push`
|
||||
|
||||
You do NOT add the repos directly anywhere on the server; you do it by
|
||||
cloning, adding keys, and pushing.
