This is useful if the internal and the external URL don't match (e.g. in Docker). +* `LFS_START_SERVER`: **false**: Enables git-lfs support. +* `DB_TYPE`: **sqlite3**: The database type in use \[mysql, postgres, mssql, sqlite3\]. +* `DB_HOST`: **localhost:3306**: Database host address and port. +* `DB_NAME`: **gitea**: Database name. +* `DB_USER`: **root**: Database username. +* `DB_PASSWD`: **"\"**: Database user password. Use \`your password\` for quoting if you use special characters in the password. +* `INSTALL_LOCK`: **false**: Disallow access to the install page. +* `SECRET_KEY`: **""**: Global secret key. This should be changed. If this has a value and `INSTALL_LOCK` is empty, `INSTALL_LOCK` will automatically set to `true`. +* `DISABLE_REGISTRATION`: **false**: Disable registration, after which only admin can create accounts for users. +* `REQUIRE_SIGNIN_VIEW`: **false**: Enable this to force users to log in to view any page. + +# Customization + +Customization files described [here](https://docs.gitea.io/en-us/customizing-gitea/) should +be placed in `/var/lib/gitea/custom` directory.
