Docker for Gogs

Visit Docker Hub 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 repoistories and Gogs data:

/var/gogs
|-- git
|   |-- gogs-repositories
|-- ssh
|   |-- # ssh public/private keys for Gogs
|-- gogs
    |-- conf
    |-- data
    |-- log
    |-- templates

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).
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.
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/).

Full documentation of settings can be found here.

Upgrade

❗❗❗Make sure you have volumed data to somewhere outside Docker container❗❗❗

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.

Troubleshooting

If you see the following error:

checkVersion()] [E] Binary and template file version does not match

Run rm -fr /var/gogs/gogs/templates/ should fix this it. Just remember to backup templates file if you have made modifications youself.

Known Issues

Use ctrl+c when clone through SSH makes Docker exit unexpectedly
