Solve Local Capistrano Deployment Issue

Local Capistrano Deployment Issue

I have an inssue when deploying PHP application on "local" machine (e.g. deploying app to same machine where executing capistrano deploy.) using Capistrano.
The cause is when capistrano creates temporary directory for destination (remote) directory and directory for source (local) directory point to same directory.
This problem does not happen when you deploy to different machine.

Solution

Add the below code to your deploy.rb!! Just change the name for temoprary directory used during deployment name.

# put this line at the top of app.yml in order to use SecureRandom methods
require "securerandom"

# set flag true when local deployment
set :deploy_to_self, "true"

# hook tasks
before :deploy, "local:create_dir"
after  :deploy, "local:clean_dir"

####################################
# setup copy_dir, copy_remote_dir
# when deploying to machine which this script is running on to avoid copy issue
#
namespace :local do
  desc <<-DESC
    set copy_dir, copy_remote_dir when deploying to machine which this script is running on (e.g. same machine)
  DESC
  task :create_dir do
    set :random_str, SecureRandom.base64(6).gsub(/[$=+\/]/,65.+(rand(25)).chr)
    set :cap_temp_dir, "/tmp/capistrano_#{random_str}"
    if exists?(:local_deploy) && local_deploy == "true"
      set :copy_dir, "#{cap_temp_dir}/local/"
      set :copy_remote_dir, "#{cap_temp_dir}/remote"
      print "    creating #{copy_dir}.\n"
      run "mkdir -p #{copy_dir}"
      print "    creating #{copy_remote_dir}.\n"
      run "mkdir -p #{copy_remote_dir}"
    end
  end
end

####################################
# clean up temp dir created when deploying

    clean up temp dirs created when deploying
  DESC
  task :clean_dir do
    if exists?(:cap_temp_dir)
      print "    cleaning up temp directory... #{cap_temp_dir}"
      run "rm -r -f #{cap_temp_dir}"
    end
  end
