# Configuration Cheat Sheet

This is a cheat sheet for the Gitea configuration file. It contains most of the settings
that can be configured as well as their default values.

Any changes to the Gitea configuration file should be made in `custom/conf/app.ini`
or any corresponding location. When installing from a distribution, this will
typically be found at `/etc/gitea/conf/app.ini`.

The defaults provided here are best-effort (not built automatically). They are
accurately recorded in [app.ini.sample](https://github.com/go-gitea/gitea/blob/master/custom/conf/app.ini.sample)
(s/master/\<tag|release\>). Any string in the format `%(X)s` is a feature powered
by [ini](https://github.com/go-ini/ini/#recursive-values), for reading values recursively.

Values containing `#` or `;` must be quoted using `` ` `` or `"""`.

**Note:** A full restart is required for Gitea configuration changes to take effect.

## Overall (`DEFAULT`)

- `APP_NAME`: **Gitea: Git with a cup of tea**: Application name, used in the page title.
- `RUN_USER`: **git**: The user Gitea will run as. This should be a dedicated system
   (non-user) account. Setting this incorrectly will cause Gitea to not start.
- `RUN_MODE`: **dev**: For performance and other purposes, change this to `prod` when
   deployed to a production environment. The installation process will set this to `prod`
   automatically. \[prod, dev, test\]

## Repository (`repository`)

   an absolute path.

- `CONN_MAX_LIFETIME` **0 or 3s**: Sets the maximum amount of time a DB connection may be reused - default is 0, meaning there is no limit (except on MySQL where it is 3s - see #6804 & #7071).
  
Please see #8540 & #8273 for further discussion of the appropriate values for `MAX_OPEN_CONNS`, `MAX_IDLE_CONNS` & `CONN_MAX_LIFETIME` and their
relation to port exhaustion.

## Markup (`markup`)

Gitea can support Markup using external tools. The example below will add a markup named `asciidoc`.

```ini
[markup.asciidoc]
ENABLED = true
FILE_EXTENSIONS = .adoc,.asciidoc
RENDER_COMMAND = "asciidoc --out-file=- -"
IS_INPUT_FILE = false
```

   command. Multiple extentions needs a comma as splitter.

Two special environment variables are passed to the render command:

- `GITEA_PREFIX_RAW`, which contains the current URL prefix in the `raw` path tree. To be used as prefix for image paths.


Gitea supports customizing the sanitization policy for rendered HTML. The example below will support KaTeX output from pandoc.

```ini
[markup.sanitizer.TeX]
; Pandoc renders TeX segments as <span>s with the "math" class, optionally
; with "inline" or "display" classes depending on context.
ELEMENT = span
ALLOW_ATTR = class
REGEXP = ^\s*((math(\s+|$)|inline(\s+|$)|display(\s+|$)))+
```

 - `ALLOW_ATTR`: The attribute this policy allows. Must be non-empty.
