dotsync

dotsync keeps your local dotfiles in sync with a git repository and keeps multiple remote machines in sync, either with them pulling from the git repo or pushed via rsync

Master servers can be assigned, for cases where groups of machines are behind firewalls or only accessible from a certain location.

Requirements

dotsync assumes that you have ssh setup correctly, with ssh-agent and configs for correct usernames etc, if you can't 'ssh hostname' it probably wont work and if your asked for passwords it will take hours with any number of machines.

Installation

If you already have your dotfiles in a git repo...

cd ~/.dotfiles
git submodule add git@github.com:dotphiles/dotsync.git
git submodule update --init

If you dont...

Fork the main project on github

git clone --recursive git@github.com:*username*/dotphiles.git ~/.dotfiles

Copy your dotfiles into ~/.dotfiles without the dot...

List your dotfiles in dotsyncrc without the dot...

Checkin your changes...

git commit -a -m "Initial Commit"
git push

Then, symlink your dotfiles into place...

~/.dotfiles/dotsync/bin/dotsync -L

See the Configuration section for configuration info.

Then add hosts into dotsyncrc and dotsync -I -H hostname (at your own risk!)

Usage

-I          - Initialise a machine using dotsync
-L          - Symlink available dotfiles into $HOME
-u          - Update to the latest copy of dotfiles
-U          - Update to the latest copy of dotfiles inc submodules
-P          - Push any local changes back to the repo (git only)
-H host     - Perform action against host listed in config, can be 'ALL'
-a          - Updates dotfiles on all known machines
-A          - Updates dotfiles and submodules on all known machines
-r          - Use rsync instead of git
-f conf     - Config file, defaults to '~/.dotsyncrc' or '$DOTSYNCRC'
-d dotfiles - Location of dotfiles, defaults to '~/.dotfiles'
-l          - List configured hosts and dotfiles to symlink
-c          - Run an arbitrary shell command on all known machines
-g          - Same as -c, but only on git configured machines
-v          - Verbose
-h          - Show help message

Configuration

~/.dotsyncrc

This config determines which hosts to sync, how, where from and which dotfiles to symlink into your homedir.

This file can be included in the repo, and dotsync will use it if its not already symlinked.

See templates/dotsyncrc

~/.dotfiles/.gitignore

Controls which files are ignored from being added to the git repo, add any temporary and 'secret' files here.

See templates/gitignore

~/dotfiles/.rsyncignore

Controls which files are ignored when rsyncing a remote host, add any temporary and 'secret' files here.

See templates/rsyncignore

Custom Dotfiles

Sometimes its handy to link a specific file on a specific machine, or to have a local dotfile in place instead.

If you have the following in dotsyncrc

[files]
dotfile
[endfiles]

dotsync will look for

~/$DOTFILES/dotfile.d/localhost
~/$DOTFILES/dotfile.d/$HOSTNAME
~/$DOTFILES/dotfile.d/$DOMAIN

And link the first one it finds instead of the standard dotfile. The localhost dotfile should be excuded from your repo.

Machine specific Dotfiles

Sometimes you have a dotfile thats only for one machine and not symlinked on any others.

If you add the following to dotsyncrc

[hosts]
hostname.example.com        git=ANY             file=dotfile1/dotfile1,dotfile2:.linkto
[endhosts]

dotsync will link the following on hostname only

~/$DOTFILES/dotfile1/dotfile1 to ~/.dotfile1
~/$DOTFILES/dotfile1 to ~/.linkto

Remote Machines

WARNING! This is the least tested and resilient code, i use it to sync a few hundred machines without problem but you can easily wipe out your ssh keys on remote machines if anything goes wrong....be prepared

dotsync is based around the idea of having lots of remote machines, that you want to sync your dotfiles to.

e.g.

         *origin*
      ----github------   remoteservers:r
    /         |        \      |
desktop:g----laptop:g----workdesktop:g
                |             |
            mac-mini:r   workservers:r

and the following dotsyncrc

[hosts]
laptop                       git=NONE
desktop                      git=laptop
mac-mini                     rsync=laptop
workdesktop                  git=laptop
workserver1                  rsync=workdesktop
workserver2                  rsync=workdesktop
workserver3                  rsync=workdesktop
remoteserver1                rsync=workdesktop
remoteserver1                rsync=workdesktop
remoteserver3                rsync=workdesktop
[endhosts]

Runing a dotsync -A on laptop would

git pull from github
connect to workdesktop & desktop & git pull dotfiles from github
rsync dotfiles to mac-mini

Runing a dotsync -A on workdesktop would

git pull from github
rsync dotfiles to workserver{1,2,3} & remoteserver{1,2,3}

These can all be done with dotsync -A -H ALL which when run on laptop, should

git pull from github
connect to workdesktop & desktop & git pull dotfiles from github
rsync dotfiles to mac-mini
ssh to workdesktop & rsync dotfiles to workserver{1,2,3} & remoteserver{1,2,3}

Backups

Existing dotfiles will be backed up in ~/.backup/dotfiles/ Existing dotfile repos will be backed up as ~/.backup/dotfiles.old/
