| 1 | +# GitLab project architecture | ||
| 2 | + | ||
| 3 | +GitLab project consists of two parts: GitLab and GitLab shell. | ||
| 4 | + | ||
| 5 | +## GitLab | ||
| 6 | + | ||
| 7 | +Web application with background jobs workers. | ||
| 8 | +Provides you with UI and most of functionality. | ||
| 9 | +For some operations like repo creation - uses GitLab shell. | ||
| 10 | + | ||
| 11 | +Uses: | ||
| 12 | + * Ruby as main language for application code and most libraries. | ||
| 13 | + * [Rails](http://rubyonrails.org/) web framework as main framework for application. | ||
| 14 | + * Mysql or postgres as main databases. Used for persistent data storage(users, project, issues etc). | ||
| 15 | + * Redis database. Used for cache and exchange data between some components. | ||
| 16 | + * Python2 because of [pygments](http://pygments.org/) as code syntax highlighter. | ||
| 17 | + | ||
| 18 | +## GitLab shell | ||
| 19 | + | ||
| 20 | +Command line ruby application. Used by GitLab through shell commands. | ||
| 21 | +It provides interface to all kind of manipulations with repositories and ssh keys. | ||
| 22 | +Full list of commands you can find in README of GitLab shell repo. | ||
| 23 | +Works on pure ruby and do not require any additional software. |
