Alpine CGit

The hyperfast web frontend for Git repositories on top of Alpine and Nginx.

CGit is a web interface (cgi) for Git repositories, written in C.

CGit features

• Basic repository browsing (logs, diffs, trees...).
• Caching of generated HTML.
• Cloneable URLs (implements dumb HTTP transport).
• Commit feeds (atom format).
• Discovery of Git repositories.
• On-the-fly archives for tags and commits.
• Plugin support e.g. syntax highlighting.
• Side-by-side diffs.
• Simple time/author statistics.
• Simple virtual hosting support (macro expansion).
• Understands GitWeb project-lists.
• Understands gitweb.owner in Git config files.
• Has an extensive filtering framework using scripts or a built-in Lua interpreter.

See CGit project for more details.

Usage

docker run --rm -it \
    -p 8787:80 \
    -v /my/repos/:/srv/git/ \
        joseluisq/alpine-cgit:2

Dockerfile

FROM joseluisq/alpine-cgit:2

Key container paths

• /etc/cgitrc: Default CGit configuration file.
• /srv/git: Default directory for Git repositories scanned by CGit.
• /var/cache/cgit: Default CGit caching directory of generated HTML.

Note that all these paths can be overwritten via Bind Mounts or Docker Volumes.

Settings via environment variables

CGit Docker image can be configured via environment variables. This is the default behavior.

• CGIT_TITLE: Website title.
• CGIT_DESC: Website description.
• CGIT_VROOT: Virtual root directory.
• CGIT_SECTION_FROM_STARTPATH: How many path elements from each repo path to use as a default section name.
• CGIT_MAX_REPO_COUNT: Number of entries to list per page on the repository index page.

Settings via custom configuration file

By default, this Docker image will use a template file located at cgit/cgit.conf which is replaced with the env settings (mentioned above) at start-up time.

However, if you want to use a custom /etc/cgitrc file then follow these steps:

1. Provide the env variable USE_CUSTOM_CONFIG=true to prevent using the default config file.
2. Provide the custom config file as a Bind Mount or Docker Volume. For example --volume my-config-file:/etc/cgitrc
3. Provide the cache-root option in your config file. For example cache-root=/var/cache/cgit
4. Provide the scan-path option in your config file. For example scan-path=/srv/git
5. Provide the repositories folder as a Bind Mount or Docker Volume. For example --volume my-repos:/srv/git

See cgitrc man page for more detailed information.
