Git workflow without a server

Git is supposed to be a decentralized system, but all the tutorials and best practice workflows I have found on Google suggest using a server (usually GitHub, or else set up your own)

I am using git for small personal projects (2-3 people), where can I find a best practice workflow for syncing changes directly between the team members machines.

Alternatively, what are some compelling arguments for why I should avoid this and instead set up a 'central' server?

Depends on what you mean by "server". Git will work happily without a central server, although many teams find it convenient to have a central repository.

If by "server", you mean "install server software", git will also work (central repository or not) without any special software, through ssh or on the file system.

See this document for possible workflows

Workflow with common repository

The workflow that many use is that all developers "push" (send) their changes to a common repository, and get all the changes from that repository. Something like this:

• Developer A pushes to central
• Developer B pushes to central
• Developer C pulls (getting changes from A and B)
• Developer A pulls (getting changes from B)
• ...

In this case the central repository can be on one of the Developers computers, on github, or any other place

Workflow with Email

You can also use git without any server, just using email. In this case the flow would be like this:

• Developer A sends changes as an email to the team
• Other developers apply the changes from the emails

This can even be done in a semi-automated way

Workflow without a central server

You can setup git to use more than one "remote" repository. The caveat is that you should never push to a repository that is checked out (that is, a Developer copy on which someone is working). So in this case the flow would be like this:

• Developer A makes changes
• Developer B makes changes
• Developer C pulls changes from A
• Developer C pulls changes from B
• Developer B pulls changes from A
• ...
• No one must ever push

IMHO this type of workflow will quickly lead to confusion and breakdown.

What you need to do first, is to think through what kind of workflow you have already and configure git to work with that. Once you have something up and running, you can fine tune it. There is no need to setup a separate computer as a server. If you are accustomed to have a central repository all you need to do is to create a bare repository that everyone pushes to. Why not on the local network?

Central repo:

mkdir foo.git
cd foo.git
git init --bare

Your repo:

mkdir foo
cd foo
git init
// add files
git add .
git commit -m "Initial commit"
git remote add origin //path/to/central/repo/foo.git
git push origin master

Other repos:

git clone //path/to/central/repo/foo.git

Now anyone can push and pull directly from master branch. This should be enough to get you started.
