Automatic Git deploys on Dreamhost

post-receive

#!/bin/bash

# Replace this line with your real domain name
DOMAIN=mydomain.com

echo
echo "-= Transferring changes to $DOMAIN =-"
echo

# Clearing git env
unset GIT_DIR
unset GIT_WORK_TREE
cd ~/$DOMAIN
git pull

echo
echo "-= Done =-"

Run in LOCAL terminal...

# Replace any brackets with real values

# Try to ssh in to DREAMHOST (ensure it no longer asks for a PW); you may want to restart Terminal
ssh [user]@[host]
cd ~
mkdir [mydomain_com].git
cd [mydomain_com].git
git init --bare
vi hooks/post-receive
# Enter the code from the "post-receive" file (in this gist); save + quit 
cd ..
git clone [mydomain_com].git [mydomain.com]
exit

# Add remote to git's list of remote repos
cd [some local git folder]
git remote add live ssh://[user]@[host]/~/[mydomain_com].git

# Push to production :)
git push live master

Setup SSH on Dreamhost (Run this in LOCAL terminal)

# Replace any brackets with real values

# Before you start this, ensure that you have added shell (ssh) access for your hosted account (not just sftp/ftp).

# You may need to generate a new ssh key; if so, follow instructions to generate ssh key
ssh-keygen -t rsa

# Add to authorized keys on DREAMHOST
# For OSX:
cat ~/.ssh/id_rsa.pub | ssh [user]@[host] "mkdir ~/.ssh; cat >> ~/.ssh/authorized_keys"
# Else:
ssh-copy-id [user]@[host]

THANK YOU! This is brilliant - I needed to chmod 755 post-receive to get it to work.

Thanks!! Any idea why it doesn't work with method of setting the work tree of the bare repo?

Not sure if this is still working, I have setup the identical configuration with my sites domain and I get the following error:
remote:
remote: -= Transferring changes to mydomain.com =-
remote:
remote: fatal: Not a git repository (or any parent up to mount point /home)
remote: Stopping at filesystem boundary (GIT_DISCOVERY_ACROSS_FILESYSTEM not set).
remote:
remote: -= Done =-
