# Docker for Gogs
|
|
|
|
Visit [Docker Hub](https://hub.docker.com/r/gogs/gogs/) or [Quay](https://quay.io/repository/gogs/gogs) see all available tags.
|
|
|
|
## Usage
|
|
|
|
To keep your data out of Docker container, we do a volume(`/var/gogs` -> `/data`) here, and you can change it based on your situation.
|
|
|
|
```
|
|
# Pull image from Docker Hub.
|
|
$ docker pull gogs/gogs
|
|
|
|
# Create local directory for volume.
|
|
$ mkdir -p /var/gogs
|
|
|
|
# Use `docker run` for the first time.
|
|
$ docker run --name=gogs -p 10022:22 -p 10080:3000 -v /var/gogs:/data gogs/gogs
|
|
|
|
# Use `docker start` if you have stopped it.
|
|
$ docker start gogs
|
|
```
|
|
|
|
Files will be store in local path `/var/gogs` in my case.
|
|
|
|
Directory `/var/gogs` keeps Git repositories and Gogs data:
|
|
|
|
/var/gogs
|
|
|-- git
|
|
| |-- gogs-repositories
|
|
|-- ssh
|
|
| |-- # ssh public/private keys for Gogs
|
|
|-- gogs
|
|
|-- conf
|
|
|-- data
|
|
|-- log
|
|
|
|
### Volume with data container
|
|
|
|
If you're more comfortable with mounting data to a data container, the commands you execute at the first time will look like as follows:
|
|
|
|
```
|
|
# Create data container
|
|
docker run --name=gogs-data --entrypoint /bin/true gogs/gogs
|
|
# Use `docker run` for the first time.
|
|
docker run --name=gogs --volumes-from gogs-data -p 10022:22 -p 10080:3000 gogs/gogs
|
|
```
|
|
|
|
## Settings
|
|
|
|
Most of settings are obvious and easy to understand, but there are some settings can be confusing by running Gogs inside Docker:
|
|
|
|
- **Repository Root Path**: keep it as default value `/home/git/gogs-repositories` because `start.sh` already made a symbolic link for you.
|
|
- **Run User**: keep it as default value `git` because `start.sh` already setup a user with name `git`.
|
|
- **Domain**: fill in with Docker container IP(e.g. `192.168.99.100`). But if you want to access your Gogs instance from a different physical machine, please fill in with the hostname or IP address of the Docker host machine.
|
|
- **SSH Port**: Use the exposed port from Docker container. For example, your SSH server listens on `22` inside Docker, but you expose it by `10022:22`, then use `10022` for this value. **Builtin SSH server is not recommended inside Docker Container**
|
|
- **HTTP Port**: Use port you want Gogs to listen on inside Docker container. For example, your Gogs listens on `3000` inside Docker, and you expose it by `10080:3000`, but you still use `3000` for this value.
|
|
- **Application URL**: Use combination of **Domain** and **exposed HTTP Port** values(e.g. `http://192.168.99.100:10080/`).

Steps to upgrade Gogs with Docker:
|
|
|
|
- `docker pull gogs/gogs`
|
|
- `docker stop gogs`
|
|
- `docker rm gogs`
|
|
- Finally, create container as the first time and don't forget to do same volume and port mapping.

## Known Issues
|
|
|
|
- `.dockerignore` seems to be ignored during Docker Hub Automated build
