Set up GIN in your lab

If you plan to set up a GIN Server in your own lab, you are more than welcome to do so. All our software is based on open source projects and therefore meant to be used, extended and modified by others. The features we implemented on top of gogs are available on Github and a non branded version is available here.

Generally, there are two options to have GIN services running in-house:

1. without Docker (for detailed Set up, see here)
2. with Docker (recommended, see Set up below)

Should you have problems or questions in the process, contact us at gitter or via dev@g-node.org. Even if you have no trouble, we would love to receive your feedback or just learn from you that you have just setup your own GIN!

Set up GIN with Docker

The easiest way to set up a GIN server is via prebuild docker containers. You will need a working Docker installation. Find instructions here. Furthermore, a dockerhub account is useful.

You start by downloading the docker image for gin@home by typing:

docker pull gnode/ginhome

after that you are all set and can start ginning with:

docker run -p 3000:3000 -p 2222:22 -d gnode/ginhome

You can now visit the website of your GIN server at port 3000 (see the first -p above) of your local machine (localhost:3000). The ssh part can be reached via port 2222 (see the second -p above). You will be greeted with a setup page which will ask you for all the necessary information.

This will map all data and configuration into the docker container, which is fine for playing around. However, should you want to use the server for data it's probably not what you want. Instead, we probably want to map the data as well as the config and log files into some folder of your local host:

docker run -v /somefolder/:/data -p 3000:3000 -p 2222:22 -d gnode/ginhome

This will map the data, configs and such into a folder on your machine (please change "somefolder" accordingly).

If you want the container to run the web service with another user and group id than 1000, you can do this by setting the corresponding environment variables on docker by running:

docker run -v /somefolder/:/data -p 3000:3000 -p 2222:22 -e GITUID="1001" -e GITGID="1001" -d gnode/ginhome

where GITUID and GITGID are followed by the numerical user and group ids respectively.

Update gin@home

To update an existing GIN docker installation you just need to pull in the changes:

docker pull gnode/ginhome

afterward, you stop the running instance with:

docker stop <containername>

<containername> can be determined with:

docker ps

After that you can start a new version using the same command that you started the original docker container with, e.g.:

docker run -v /somefolder/:/data -p 3000:3000 -p 2222:22 -d gnode/ginhome

Is Docker good for production

Yes, docker can be used for production. We are actually doing it too, it is very convenient. And you know what? Performant too!

Which database backend should I use

It's maybe not the best idea to run a multi-multi-user version using SQLite but for a lab use case it should actually be fine. For a larger audience, using a Postgres server (which you can also run with docker) is our recommendation. In such a cases, an advanced file system including proper backup and maybe deduplication, at least for the repositories, should also be considered. In any case you can contact us for assistance if you want!
