I updated to Cap 3 and it appears that
set :deploy_via, :copy is no longer supported. In the release annoucement there is a link to a video for replicating the copy
I ran into the same issue and posted a similar question on the capistrano google group.
See here: https://groups.google.com/forum/#!topic/capistrano/BRa4Vj1_mEo
Short answer: Write your own rake task.
The capistrano maintainer provided some example code, via a blog post on his website, that can be found here: http://lee.hambley.name/2013/06/11/using-capistrano-v3-with-chef.html
In the end, we've decided to go w/ a different strategy entirely, and implement a mirror repository on the same network as our servers.
There is one work in the exact same way
Capistrano 3 :copy
A copy strategy for Capistrano 3, which mimics the
:copy scm of Capistrano 2.
This Gem is inspired by and based on https://github.com/wercker/capistrano-scm-copy.
Thank wercker so much.
This will make Capistrano tar the a specific git branch, upload it to the server(s) and then extract it in the release directory.
cap uat deploy -s branch=(your release branch)
You can use its gem - https://github.com/WildZero/capistrano-scm-tar-copy
set :scm, :copy
set :include_dir, '/User/w1ldzer0/ExampleDir'
