Bash script to automatically deploy a web project

gistfile1.txt

## 1. Create git repo in user's home

    cd /home/myuser
    mkdir git
    mkdir web.git
    
    cd /home/myuser/git/web.git
    git init --bare
    
## 2. Put the post-receive script in there

    cd /home/myuser/git/web.git/hooks
    # copy the file here
    # edit it to replace "/web" in DEPLOYTO by your own www root path
    
## 3. Add the repository remote (we'll name it "prod") to your source repository

    git remote add prod ssh://myuser@yourserver.com:/home/myuser/git/web.git

## 4. Push master to that remote when you're ready

    git push prod master

post-receive

#!/bin/bash
# post-receive

# 1. Read STDIN (Format: "from_commit to_commit branch_name")
DEPLOYTO=/web

read FROM TO REFNAME
BRANCH=${REFNAME#refs/heads/}

# 2. Only deploy if master branch was pushed
if [[ "$BRANCH" != "master" ]]; then
    echo $FROM $TO $BRANCH
    echo "Not deploying because I received branch: " $BRANCH
    exit
else
    echo "Deploying to: " $DEPLOYTO
fi

# 3. Copy files to deploy directory
GIT_WORK_TREE="$DEPLOYTO" git checkout -f master

# 4.TODO: Deployment Tasks
# i.e.: Run Puppet Apply, Restart Daemons, etc
