This reference setup guides users through the setup based on `docker-compose`, but the installation
of `docker-compose` is out of scope of this documentation. To install `docker-compose` itself, follow
the official [install instructions](https://docs.docker.com/compose/install/).
## Basics
The most simple setup just creates a volume and a network and starts the `gitea/gitea:latest-rootless`
image as a service. Since there is no database available, one can be initialized using SQLite3.
Create a directory for `data` and `config` then paste the following content into a file named `docker-compose.yml`.
Note that the volume should be owned by the user/group with the UID/GID specified in the config file. By default Gitea in docker will use uid:1000 gid:1000. If needed you can set ownership on those folders with the command: `sudo chown 1000:1000 config/ data/`
If you don't give the volume correct permissions, the container may not start.
Also be aware that the tag `:latest-rootless` will install the current development version.
For a stable release you can use `:1-rootless` or specify a certain release like `:{{< version >}}-rootless`.
```yaml
version: "2"
services:
server:
image: gitea/gitea:latest-rootless
restart: always
volumes:
- ./data:/var/lib/gitea
- ./config:/etc/gitea
- /etc/timezone:/etc/timezone:ro
- /etc/localtime:/etc/localtime:ro
ports:
- "3000:3000"
- "2222:2222"
```
## Custom port
To bind the integrated ssh and the webserver on a different port, adjust
the port section. It's common to just change the host port and keep the ports within
the container like they are.
```diff
version: "2"
services:
server:
image: gitea/gitea:latest-rootless
restart: always
volumes:
- ./data:/var/lib/gitea
- ./config:/etc/gitea
- /etc/timezone:/etc/timezone:ro
- /etc/localtime:/etc/localtime:ro
ports:
- - "3000:3000"
- - "2222:2222"
+ - "80:3000"
+ - "22:2222"
```
## MySQL database
To start Gitea in combination with a MySQL database, apply these changes to the
`docker-compose.yml` file created above.
```diff
version: "2"
services:
server:
image: gitea/gitea:latest-rootless
+ environment:
+ - DB_TYPE=mysql
+ - DB_HOST=db:3306
+ - DB_NAME=gitea
+ - DB_USER=gitea
+ - DB_PASSWD=gitea
restart: always
volumes:
- ./data:/var/lib/gitea
- ./config:/etc/gitea
- /etc/timezone:/etc/timezone:ro
- /etc/localtime:/etc/localtime:ro
ports:
- "3000:3000"
- "222:22"
+ depends_on:
+ - db
+
+ db:
+ image: mysql:5.7
+ restart: always
+ environment:
+ - MYSQL_ROOT_PASSWORD=gitea
+ - MYSQL_USER=gitea
+ - MYSQL_PASSWORD=gitea
+ - MYSQL_DATABASE=gitea
+ volumes:
+ - ./mysql:/var/lib/mysql
```
## PostgreSQL database
To start Gitea in combination with a PostgreSQL database, apply these changes to
the `docker-compose.yml` file created above.
```diff
version: "2"
services:
server:
image: gitea/gitea:latest-rootless
environment:
+ - DB_TYPE=postgres
+ - DB_HOST=db:5432
+ - DB_NAME=gitea
+ - DB_USER=gitea
+ - DB_PASSWD=gitea
restart: always
volumes:
- ./data:/var/lib/gitea
- ./config:/etc/gitea
- /etc/timezone:/etc/timezone:ro
- /etc/localtime:/etc/localtime:ro
ports:
- "3000:3000"
- "2222:2222"
+ depends_on:
+ - db
+
+ db:
+ image: postgres:9.6
+ restart: always
+ environment:
+ - POSTGRES_USER=gitea
+ - POSTGRES_PASSWORD=gitea
+ - POSTGRES_DB=gitea
+ volumes:
+ - ./postgres:/var/lib/postgresql/data
```
## Named volumes
To use named volumes instead of host volumes, define and use the named volume
within the `docker-compose.yml` configuration. This change will automatically
create the required volume. You don't need to worry about permissions with
named volumes; Docker will deal with that automatically.
```diff
version: "2"
+volumes:
+ gitea:
+ driver: local
+
services:
server:
image: gitea/gitea:latest-rootless
restart: always
volumes:
- - ./data:/var/lib/gitea
+ - gitea-data:/var/lib/gitea
- - ./config:/etc/gitea
+ - gitea-config:/etc/gitea
- /etc/timezone:/etc/timezone:ro
- /etc/localtime:/etc/localtime:ro
ports:
- "3000:3000"
- "2222:2222"
```
MySQL or PostgreSQL containers will need to be created separately.
## Custom user
You can choose to use a custom user (following --user flag definition https://docs.docker.com/engine/reference/run/#user).
As an example to clone the host user `git` definition use the command `id -u git` and add it to `docker-compose.yml` file:
Please make sure that the mounted folders are writable by the user.
```diff
version: "2"
services:
server:
image: gitea/gitea:latest-rootless
restart: always
+ user: 1001
volumes:
- ./data:/var/lib/gitea
- ./config:/etc/gitea
- /etc/timezone:/etc/timezone:ro
- /etc/localtime:/etc/localtime:ro
ports:
- "3000:3000"
- "2222:2222"
```
## Start
To start this setup based on `docker-compose`, execute `docker-compose up -d`,
to launch Gitea in the background. Using `docker-compose ps` will show if Gitea
started properly. Logs can be viewed with `docker-compose logs`.
To shut down the setup, execute `docker-compose down`. This will stop
and kill the containers. The volumes will still exist.
Notice: if using a non-3000 port on http, change app.ini to match
`LOCAL_ROOT_URL = http://localhost:3000/`.
## Install
After starting the Docker setup via `docker-compose`, Gitea should be available using a
favorite browser to finalize the installation. Visit http://server-ip:3000 and follow the
installation wizard. If the database was started with the `docker-compose` setup as
documented above, please note that `db` must be used as the database hostname.
## Environments variables
You can configure some of Gitea's settings via environment variables:
(Default values are provided in **bold**)
*`APP_NAME`: **"Gitea: Git with a cup of tea"**: Application name, used in the page title.
*`SSH_DOMAIN`: **localhost**: Domain name of this server, used for the displayed clone URL in Gitea's UI.
*`SSH_PORT`: **2222**: SSH port displayed in clone URL.
*`SSH_LISTEN_PORT`: **%(SSH\_PORT)s**: Port for the built-in SSH server.
*`DISABLE_SSH`: **false**: Disable SSH feature when it's not available.
*`HTTP_PORT`: **3000**: HTTP listen port.
*`ROOT_URL`: **""**: Overwrite the automatically generated public URL. This is useful if the internal and the external URL don't match (e.g. in Docker).
*`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`: **"\<empty>"**: 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. If using host volumes, it's quite easy to access these
files; for named volumes, this is done through another container or by direct access at
`/var/lib/docker/volumes/gitea_gitea/_/var_lib_gitea`. The configuration file will be saved at
`/etc/gitea/app.ini` after the installation.
# Upgrading
:exclamation::exclamation: **Make sure you have volumed data to somewhere outside Docker container** :exclamation::exclamation:
To upgrade your installation to the latest release:
```
# Edit `docker-compose.yml` to update the version, if you have one specified
# Pull new images
docker-compose pull
# Start a new container, automatically removes old one
docker-compose up -d
```
# Upgrading from standard image
- Backup your setup
- Change volume mountpoint from /data to /var/lib/gitea
- If you used a custom app.ini move it to a new volume mounted to /etc/gitea
## Managing Deployments With Environment Variables
In addition to the environment variables above, any settings in `app.ini` can be set or overridden with an environment variable of the form: `GITEA__SECTION_NAME__KEY_NAME`. These settings are applied each time the docker container starts. Full information [here](https://github.com/go-gitea/gitea/tree/master/contrib/environment-to-ini).
These environment variables can be passed to the docker container in `docker-compose.yml`. The following example will enable an smtp mail server if the required env variables `GITEA__mailer__FROM`, `GITEA__mailer__HOST`, `GITEA__mailer__PASSWD` are set on the host or in a `.env` file in the same directory as `docker-compose.yml`:
```bash
...
services:
server:
environment:
- GITEA__mailer__ENABLED=true
- GITEA__mailer__FROM=${GITEA__mailer__FROM:?GITEA__mailer__FROM not set}
- GITEA__mailer__MAILER_TYPE=smtp
- GITEA__mailer__HOST=${GITEA__mailer__HOST:?GITEA__mailer__HOST not set}
- GITEA__mailer__PASSWD="""${GITEA__mailer__PASSWD:?GITEA__mailer__PASSWD not set}"""
```
To set required TOKEN and SECRET values, consider using gitea's built-in [generate utility functions](https://docs.gitea.io/en-us/command-line/#generate).
