Ask HN: How do you sync your Git repos across machines at home?

5 points by multiplied ↗ HN
I have a multi machine setup and I don't want to use a third party service as a proxy to what I could be doing locally.

One obvious answer is to stand up my own local git server, perhaps finally put those Raspberry-pi's.

Any suggestions to improve upon this?

Even if I do go down the path of the raspberry pi, how do I configure it to hide behind the router where it is shielded from the external internet. (I want it completely disjointed from the internet if possible)

what, no firewall?...some bots would be happy to know ur ip address

about git, yes a server is the answer

multiplied
Yeah of course a firewall, I just don't know enough about the exact setup there, and that's part of my question.

Diving into that rabbit hole now.

I have my git repos in one folder ~/git and then use syncthing to sync across all machines. It works great, I can start doing changes on one machine and then pick up the work on another machine without interruption
multiplied
I was thinking about this, but how does syncthing handle conflicts?

A bare repo on a server, which I `got push` to and `git pull` from.

Locally hosted server? AWS ECS instance?

I also realize there's Amazon CodeCommit, interesting.

You can setup glusterfs incredibly easily. When you write to one dir it’ll auto replicate to N machines. Did this over the weekend and it took me no time at all. Support is realistically Linux only IIRC with some MacFuse stuff for OSX

You already have everything you need to do this with just git. Just make a repo (might need to be a bare repo) on whatever machine you want to make the remote and then clone from it using ssh on the other machines. Then you can push and pull just as if the remote was in github or whatever.

If you want more functionality than that, gitlab has a free tier that can be self-hosted. same with gittea.

You don't need to use a bare repo necessarily if you want to push/pull between two working repos, without a central "bare" repo locally, you just need to tell git to update when receiving:

`git config receive.denyCurrentBranch updateInstead`

I use tailscale to access my machines around the world. It's secure and private. Nobody on the internet knows about this machines, even though they are servers. Easy to configure

Tailscale is one of those services that feel too good to be true. I have known about it but can't get myself to trust it.

I agree about too good to be true. I just can't believe it's free for up to 3 users and many machines. But if you look under the hood there is nothing there that you can't build on your own. It's just more hassle to do it. You can install wireguard on every machine that you own and you can manage the keys by yourself, you can add routing tables and internal DNS service. Tailscale just packages that in nice UI with centralized management.

I run a self hosted gogs instance. Centralized storage is much easier to backup.

Interesting, thanks for bringing it up.
