We provide automatically updated Docker images within our Docker Hub organization. It is up to you and your deployment to always use the latest stable tag or to use another service that updates the Docker image for you.
This reference setup guides you through the setup based on `docker-compose`, the installation of `docker-compose` is out of scope of this documentation. To install `docker-compose` 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` image as a service. Since there is no database available you can start it only with SQLite3. Create a directory like `gitea` and paste the following content into a file named `docker-compose.yml`.
```yaml
version: "2"
networks:
gitea:
external: false
services:
server:
image: gitea/gitea:latest
restart: always
networks:
- gitea
volumes:
- ./gitea:/data
ports:
- 3000:3000
- 222:22
```
## Custom port
To bind the integrated openSSH daemon and the webserver on a different port, you just need to 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"
networks:
gitea:
external: false
services:
server:
image: gitea/gitea:latest
restart: always
networks:
- gitea
volumes:
- ./gitea:/data
ports:
- - 3000:3000
- - 222:22
+ - 8080:3000
+ - 2221:22
```
## MySQL database
To start Gitea in combination with a MySQL database you should apply these changes to the `docker-compose.yml` file created above.
```diff
version: "2"
networks:
gitea:
external: false
services:
server:
image: gitea/gitea:latest
restart: always
networks:
- gitea
volumes:
- ./gitea:/data
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
+ networks:
+ - gitea
+ volumes:
+ - ./mysql:/var/lib/mysql
```
## PostgreSQL database
To start Gitea in combination with a PostgreSQL database you should apply these changes to the `docker-compose.yml` file created above.
```diff
version: "2"
networks:
gitea:
external: false
services:
server:
image: gitea/gitea:latest
restart: always
networks:
- gitea
volumes:
- ./gitea:/data
ports:
- 3000:3000
- 222:22
+ depends_on:
+ - db
+
+ db:
+ image: postgres:9.6
+ restart: always
+ environment:
+ - POSTGRES_USER=gitea
+ - POSTGRES_PASSWORD=gitea
+ - POSTGRES_DB=gitea
+ networks:
+ - gitea
+ volumes:
+ - ./postgres:/var/lib/postgresql/data
```
## Named volumes
To use named volumes instead of host volumes you just have to define and use the named volume within the `docker-compose.yml` configuration. This change will automatically create the required volume.
```diff
version: "2"
networks:
gitea:
external: false
+volumes:
+ gitea:
+ driver: local
+
services:
server:
image: gitea/gitea:latest
restart: always
networks:
- gitea
volumes:
- - ./gitea:/data
+ - gitea:/data
ports:
- 3000:3000
- 222:22
```
If you are using MySQL or PostgreSQL it's up to you to create named volumes for these containers as well.
## Start
To start this setup based on `docker-compose` you just have to execute `docker-compose up -d` to launch Gitea in the background. You can see if it started properly via `docker-compose ps`, and you can tail the log output via `docker-compose logs`.
If you want to shutdown the setup again just execute `docker-compose down`, this will stop and kill the containers, the volumes will still exist.
After starting the Docker setup via `docker-compose` you should access Gitea with your favorite browser to finalize the installation. Please visit http://server-ip:3000 and follow the installation wizard. If you have started a database with the `docker-compose` setup as documented above please note that you have to use `db` as the database hostname.
# Customization
Customization files described [here](https://docs.gitea.io/en-us/customizing-gitea/) should be placed in `/data/gitea` directory. If you are using host volumes it's quite easy to access these files, for named volumes you have to do it through another container or you should directly access `/var/lib/docker/volumes/gitea_gitea/_data`. The configuration file will be saved at `/data/gitea/conf/app.ini` after the installation.
