Cgit

cgit is a fast web-interface (CGI) for git written in the C programming language. It makes it possible for potential contributors to track and view project source code from the web instead of through a git client.

Installation

Note: It is very recommendable that you already have a directory with an active .git working in your server. If you don't have one, install gitolite or a similar program before going further.

Install the package that contains cgit and git.

apk add cgit git

Open up /etc/cgitrc with your favorite editor, in this case is vim.

vim /etc/cgitrc

If you want to show an specific repository your configuration should look something like this:

Contents of /etc/cgitrc

virtual-root=/
repo.path=/var/lib/git/repositories/YOUR_GIT_REPO.git/
repo.url=CUSTOM_GIT_URL

If you want to scan and show all the repositories you have, your configuration should look something like this:

Contents of /etc/cgitrc

virtual-root=/
scan-path=/var/lib/git/repositories/

Run cgit using spawn-fcgi and fcgiwrap

Install spawn-fcgi and fcgiwrap

apk add fcgiwrap spawn-fcgi

Create a new service by doing a symbolic link.

ln -s spawn-fcgi /etc/init.d/spawn-fcgi.cgit

Note: You should also modify the file and add -f after ${FCGI_PROGRAM} on line 99. Otherwise you will have no log and problems will be impossible to debug.

Create a configuration file called spawn-fcgi.cgit in /etc/conf.d/ ; the service will run fcgiwrap automatically everytime is called. It should look exactly like this:

Contents of /etc/conf.d/spawn-fcgi.cgit

FCGI_PORT=1234
FCGI_PROGRAM=/usr/bin/fcgiwrap

Note: You should consider using unix domain sockets instead.

Start the newly created service.

rc-service spawn-fcgi.cgit start

Run cgit with a web service

Configure Lighttpd to work with cgit

Install the package that contains lighttpd if you haven't already.

apk add lighttpd

Create a cgit.conf file into the lighttpd directory with the following content:

Contents of /etc/lighttpd/cgit.conf

server.modules += ("mod_redirect",
                  "mod_alias",
                  "mod_cgi",
                  "mod_fastcgi",
                  "mod_rewrite" )

var.webapps  = "/usr/share/webapps/"
$HTTP["url"] =~ "^/cgit" {
    server.document-root = webapps
    server.indexfiles = ("cgit.cgi")
    cgi.assign = ("cgit.cgi" => "")
    mimetype.assign = ( ".css" => "text/css" )
}
url.redirect = (
    "^/git/(.*)$" => "/cgit/cgit.cgi/$1",
)

Finally, add the following line to the lighttpd.conf file:

Contents of /etc/lighttpd/lighttpd.conf

include "cgit.conf"

Restart the lighttpd service.

rc-service lighttpd restart

Configure NGINX to work with cgit pointing to a subdomain

Install the package that contains NGINX if you haven't already.

apk add nginx

Create a custom configuration in the NGINX's conf.d directory.

vim /etc/nginx/conf.d/git.your_domain.com.conf

The file should look something like this:

Contents of /etc/nginx/conf.d/git.your_domain.com.conf

server {
    server_name git.your_domain.com;
    root /usr/share/webapps/cgit;
    try_files $uri @cgit;
    location @cgit {
        include fastcgi_params;
        fastcgi_pass localhost:1234;
        fastcgi_param SCRIPT_FILENAME $document_root/cgit.cgi;
        fastcgi_param PATH_INFO $uri;
        fastcgi_param QUERY_STRING $args;
        }
}

Restart the NGINX service.

rc-service nginx restart
