rsync-deploy

A server deploy script designed to quickly deploy a site with release versions while simultaneously limiting downtime due to rollbacks, failed deploys, and simultaneous deploys.

The script creates a cache on the server and updates it via rsync. After updating the cache, the build is copied into a numerically-ordered release folder then sym-linked a consistent directory for public access. This allows for rollbacks and recovery from failed deploys.

Throughout the entire deploy process, a lockfile is present to prevent simultaneous deploys.

I use rsync-deploy to deploy chauncey.io; it's worked great for me! Still, I'd like some more eyes on the code before I make this release a v1 so if you have suggestions after trying out rsync-deploy, please submit an issue and I'll take it into consideration.

Usage

In particular, notice the directory structure.

$ rsync-deploy --help

  Usage :  usage [options] [--]

  If using .rsync-deploy-rc, run the script from the same directory.

  Options:
  -h|--help       Display this message
  -v|--version    Display script version

  -i|--init       Initialize the deploy location
  -d|--deploy     Deploy the site
  -r|--rollback   Rollback to a previous version of the site
  -u|--unlock     Remove lockfile

  Directory structure:
  /var/www/chauncey.io/ # path_deploy_to
   |-  cache/           # dir_deploy_cache - rsync to save bandwidth
   |-  current          # a symlink to the current release in releases/
   |-  deploy.lock      # lock_file - help prevent multiple ongoing deploys
   |-  last_version     # contains the number of the last release
   '-  releases/        # dir_deploy_releases - one subdir per release
       |- 1/
       |- 2/
       |- 3/
       '- ...

Be sure to first run rsync-deploy --init, which will setup the site on your server!

Dependencies

Rsync

Of course! However, if you're on OS X you may wish to use Bombich's rsync for improvements related to resource forks.

ssh-key

For better security, an ssh-key is required for use of this script. If you don't already use one, see this tutorial.

Installation

rsync-deploy.zsh

Add rsync-deploy.zsh to one of the following:

• To /usr/local/bin, or similar
• As a dependency in the root level of your project

Ensure it is executable:

chmod +x rsync-deploy.zsh

.rsync-deploy-rc

Customize then add .rsync-deploy-rc to the root level of any project you wish to deploy, one file per project. Every variable seen here is required. Set them accordingly.

path_deploy_from="${PWD}"                     # read in the dir of the config file
path_deploy_to="/var/www/your-site-path-here" # important!
dir_deploy_cache="cache"
dir_local_stage="_builds/production"

username="ChaunceyGarrett"                    # important!
hostname="chauncey.io"                        # important!
