# Installation with Docker
|
|
|
|
Gitea provides automatically updated Docker images within its Docker Hub organization. It is
|
|
possible to always use the latest stable tag or to use another service that handles updating
|
|
Docker images.
|
|
|
|
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`
|
|
image as a service. Since there is no database available, one can be initialized using SQLite3.
|
|
Create a directory like `gitea` and 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.
|
|
If you don't give the volume correct permissions, the container may not start.
|
|
Also be aware that the tag `:latest` will install the current development version.
|
|
For a stable release you can use `:1` or specify a certain release like `:{{< version >}}`.
|
|
|
|
```yaml
|
|
version: "2"
|
|
|
|
networks:
|
|
gitea:
|
|
external: false
|
|
|
|
services:
|
|
server:
|
|
image: gitea/gitea:latest
|
|
environment:
|
|
- USER_UID=1000
|
|
- USER_GID=1000
|
|
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, 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"
|

|
|

|
|
gitea:
|
|
external: false
|
|
|
|
services:
|
|

|
|
+ - "8080:3000"
|
|
+ - "2221:22"
|
|
```
|
|
|
|
## MySQL database
|
|
|
|
To start Gitea in combination with a MySQL database, apply these changes to the
|
|
`docker-compose.yml` file created above.
|
|
|
|
```diff
|
|

|
|

|
|
+ 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"
|
|
|
|
networks:
|
|
gitea:
|
|
external: false
|
|
|
|
services:
|
|
server:
|
|
image: gitea/gitea:latest
|
|
environment:
|
|
- USER_UID=1000
|
|
- USER_GID=1000
|
|
+ - DB_TYPE=postgres
|
|
+ - DB_HOST=db:5432
|
|
+ - DB_NAME=gitea
|
|
+ - DB_USER=gitea
|
|
+ - DB_PASSWD=gitea
|
|
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, 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"
|
|
|
|
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"
|
|
```
|
|
|
|
MySQL or PostgreSQL containers will need to be created separately.
|
|
|
|
## 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.
|
|
* `RUN_MODE`: **dev**: For performance and other purposes, change this to `prod` when deployed to a production environment.
|
|
* `SSH_DOMAIN`: **localhost**: Domain name of this server, used for the displayed clone URL in Gitea's UI.
|
|
* `SSH_PORT`: **22**: SSH port displayed in clone URL.
|
|
* `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).
|
|
* `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`: **"\<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.
|
|
* `USER_UID`: **1000**: The UID (Unix user ID) of the user that runs Gitea within the container. Match this to the UID of the owner of the `/data` volume if using host volumes (this is not necessary with named volumes).
|
|
* `USER_GID`: **1000**: The GID (Unix group ID) of the user that runs Gitea within the container. Match this to the GID of the owner of the `/data` volume if using host volumes (this is not necessary with named volumes).
|
|
|
|
# Customization
|
|
|
|
Customization files described [here](https://docs.gitea.io/en-us/customizing-gitea/) should
|
|
be placed in `/data/gitea` 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/_data`. The configuration file will be saved at
|
|
`/data/gitea/conf/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
|
|
```
|
|
|
|
# SSH Container Passthrough
|
|
|
|
Since SSH is running inside the container, you'll have to pass SSH from the host to the
|
|
container if you wish to use SSH support. If you wish to do this without running the container
|
|
SSH on a non-standard port (or move your host port to a non-standard port), you can forward
|
|
SSH connections destined for the container with a little extra setup.
|
|
|
|
This guide assumes that you have created a user on the host called `git` which shares the same
|
|
UID/GID as the container values `USER_UID`/`USER_GID`. You should also create the directory
|
|
`/var/lib/gitea` on the host, owned by the `git` user and mounted in the container, e.g.
|
|
|
|
```
|
|
services:
|
|
server:
|
|
image: gitea/gitea:latest
|
|
environment:
|
|
- USER_UID=1000
|
|
- USER_GID=1000
|
|
restart: always
|
|
networks:
|
|
- gitea
|
|
volumes:
|
|
- /var/lib/gitea:/data
|
|
ports:
|
|
- "3000:3000"
|
|
- "127.0.0.1:2222:22"
|
|
```
|
|
|
|
You can see that we're also exposing the container SSH port to port 2222 on the host, and binding this
|
|
to 127.0.0.1 to prevent it being accessible external to the host machine itself.
|
|
|
|
On the **host**, you should create the file `/app/gitea/gitea` with the following contents and
|
|
make it executable (`chmod +x /app/gitea/gitea`):
|
|
|
|
```
|
|
#!/bin/sh
|
|
ssh -p 2222 -o StrictHostKeyChecking=no git@127.0.0.1 "SSH_ORIGINAL_COMMAND=\"$SSH_ORIGINAL_COMMAND\" $0 $@"
|
|
```
|
|
|
|
Your `git` user needs to have an SSH key generated:
|
|
|
|
```
|
|
sudo -u git ssh-keygen -t rsa -b 4096 -C "Gitea Host Key"
|
|
```
|
|
|
|
Still on the host, symlink the container `.ssh/authorized_keys` file to your git user `.ssh/authorized_keys`.
|
|
This can be done on the host as the `/var/lib/gitea` directory is mounted inside the container under `/data`:
|
|
|
|
```
|
|
ln -s /var/lib/gitea/git/.ssh/authorized_keys /home/git/.ssh/authorized_keys
|
|
```
|
|
|
|
Then echo the `git` user SSH key into the authorized_keys file so the host can talk to the container over SSH:
|
|
|
|
```
|
|
echo "no-port-forwarding,no-X11-forwarding,no-agent-forwarding,no-pty $(cat /home/git/.ssh/id_rsa.pub)" >> /var/lib/gitea/git/.ssh/authorized_keys
|
|
```
|
|
|
|
Now you should be able to use Git over SSH to your container without disrupting SSH access to the host.
|
|
|
|
Please note: SSH container passthrough will work only if using opensshd in container, and will not work if
|
|
`AuthorizedKeysCommand` is used in combination with setting `SSH_CREATE_AUTHORIZED_KEYS_FILE=false` to disable
|
|
authorized files key generation.
