Capistrano::Rsync for Capistrano v3

[gem-badge]: https://badge.fury.io/rb/capistrano-rsync-bladrak.svg

This repository is a fork of https://github.com/moll/capistrano-rsync which doesn't seem to be maintained anymore.

It has all the capabilities of the original repo, and some other features. Moreover, I will try to maintain it.

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 the new 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%.
Currently works only with Git (as does Capistrano v3), so please shout out your interest in other SCMs.

Added features

Compared to moll's version, I added the following features:

setting the :rsync_target_dir option in order to choose where the code will be stored locally
implemented a set_current_revision task to be compliant with Capistrano
added an option to sparse checkout the repository before rsyncing it, improving performance for large repositories
added an option to limit the clone depth (defaults to 1) to limit used space while deploying

Using

Install with:

gem install capistrano-rsync-bladrak

Set rsync as the SCM to use

set :scm, :rsync

Optionally 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

Clones and updates your repository to rsync_stage (defaults to tmp/deploy) on your local machine.
Checks out the branch set in the branch variable (defaults to master).
If rsync_cache set (defaults to shared/deploy), rsyncs to that directory on the server.
If rsync_cache set, copies the content of that directory to a new release directory.
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 /config/database.yml
  --exclude /test/***
]

Precompile assets before deploy

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

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

after "rsync:stage_done", "precompile"

Deploy release without symlinking the current directory

cap rsync:release

Bypass clone stage

set :bypass_git_clone, true

Troubleshooting

If you need to hook after rsync:stage_done in your deploy.rb, the rsync namespace is not loaded yet.

So do it like this in your deploy.rb:

namespace :rsync do
    # Create an empty task to hook with. Implementation will be come next
    task :stage_done

    # Then add your hook
    after :stage_done, :my_task do
      # Do some stuff.
    end
end

Configuration

Set Capistrano variables with set name, value.

Name	Default	Description
repo_url	`.`	The path or URL to a Git repository to clone from.
branch	`master`	The Git branch to checkout.
git_remote	`origin`	The remote to use for Git checkout.
rsync_stage	`tmp/deploy`	Path where to clone your repository for staging, checkouting and rsyncing. Can be both relative or absolute.
rsync_cache	`shared/deploy`	Path where to cache your repository on the server to avoid rsyncing from scratch each time. Can be both relative or absolute. Set to `nil` if you want to disable the cache.
rsync_options	`[]`	Array of options to pass to `rsync`.
rsync_sparse_checkout	`[]`	Array of directories to checkout (checks out all if empty)
rsync_depth	`1`	Sets the --depth argument value for the git operations; this is set to 1 by default as you won't need the git history
rsync_checkout	`branch`	Is the `:branch` symbol containing a branch, tag or revision?
rsync_checkout_tag	`false`	Is the `:branch` symbol containing a branch or a tag? `Deprecated`
rsync_copy	`rsync --archive --acls --xattrs`	The command used to copy from remote cache to remote release
rsync_target_dir	`.`	The local directory within `:rsync_stage` to clone to & deploy (useful if you want to keep cache of several branches/tags for instance)
enable_git_submodules	`false`	Should we fetch submodules as well?
reset_git_submodules_before_update	`false`	Do a reset hard and clean force on submodules (in case you do modifications on working copies)?
