Capistrano::Rsync for Capistrano v3

Gem Version

Deploy with Rsync to your server from any local (or remote) repository when using Capistrano. Saves you from having to install Git on your production machine and allows you to customize which files you want to deploy. Also allows you to easily precompile things on your local machine before deploying.

Tour

  • Works with Capistrano v3 (source code) versions >= 3.0.0pre14 and < 4.
  • Suitable for deploying any apps, be it Ruby, Rails, Node.js or others.
  • Exclude files from being deployed with Rsync's --exclude options.
  • Precompile files or assets easily before deploying, like JavaScript or CSS.
  • Caches your previously deployed code to speed up deployments ~1337%.
  • Works with git and svn.

Using Mina instead of Capistrano? I've (actuall not me, but Moll) built Mina::Rsync as well.

Using

Install with:

gem install capistrano-rsync-local

Require it at the top of your Capfile (or config/deploy.rb):

require "capistrano/rsync"

Set some rsync_options to your liking:

set :rsync_options, %w[--recursive --delete --delete-excluded --exclude .git*]

And after setting regular Capistrano options, deploy as usual!

cap deploy

Implementation

  1. Clones and updates your repository to rsync_stage (defaults to tmp/deploy) on your local machine.
  2. Checks out the branch set in the branch variable (defaults to master).
  3. If rsync_cache set (defaults to shared/deploy), rsyncs to that directory on the server.
  4. If rsync_cache set, copies the content of that directory to a new release directory.
  5. If rsync_cache is nil, rsyncs straight to a new release directory.

After that, Capistrano takes over and runs its usual tasks and symlinking.

Exclude files from being deployed

If you don't want to deploy everything you've committed to your repository, pass some --exclude options to Rsync:

set :rsync_options, %w[
  --recursive --delete --delete-excluded
  --exclude .git*
  --exclude .svn*
  --exclude /config/database.yml
  --exclude /test/***
]

Precompile assets before deploy

Capistrano::Rsync runs rsync:stage before rsyncing. Hook to that like this:

task :precompile do
  Dir.chdir fetch(:rsync_stage) do
    system "rake", "assets:precompile"
  end
end

after "rsync:stage", "precompile"

Deploy release without symlinking the current directory

cap rsync:release
