How do I configure remote refs for git + capistrano 3 in ROR deployment?

Question

I am trying to use capistrano (for the first time) to deploy my rails app. First the essentials, I am using:

• ruby 1.9.3p362
• Rails 3.2.13
• rvm 1.24.7
• Capistrano 3.0.1
• Phusion Passenger 4.0.26
• Ubuntu 12.04 LTS

I get the following error when attempting to run cap production deploy

DEBUG [679a47be] fatal: No remote configured to list refs from.

My full cap production deploy output is included below

   INFO [488ba755] Running /usr/bin/env mkdir -p /tmp/AppName/ on sub.example.com
    DEBUG [488ba755] Command: /usr/bin/env mkdir -p /tmp/AppName/

deploy.rb

I have altered this file to add my git url, the app name, the deploy_to path, and the tasks inside task :restart as directed to restart Phusion Passenger.

set :application, 'AppName'
set :deploy_to, '/var/www/appname'

set :repository, "[email protected]:username/appname.git"  # Your clone URL
set :scm, "git"
set :user, "my-github-deploy-user"  # The server's user for deploys
set :scm_passphrase, "correct-password"  # The deploy user's password
set :branch, "master"
set :deploy_via, :remote_cache

# ask :branch, proc { `git rev-parse --abbrev-ref HEAD`.chomp }

set :ssh_options, {
   verbose: :debug
}

set :format, :pretty
set :log_level, :debug
# set :pty, true

set :linked_files, %w{config/database.yml}
set :linked_dirs, %w{bin log tmp/pids tmp/cache tmp/sockets vendor/bundle public/system}

# set :default_env, { path: "/opt/ruby/bin:$PATH" }
# set :keep_releases, 5

namespace :deploy do

  desc 'Restart application'
  task :restart do
    on roles(:app), in: :sequence, wait: 5 do
      # Your restart mechanism here, for example:
      execute :touch, release_path.join('tmp/restart.txt')
      # task :start do ; end
      # task :stop do ; end
      # task :restart, :roles => :app, :except => { :no_release => true } do
      #   run "#{try_sudo} touch #{File.join(current_path,'tmp','restart.txt')}"
      # end
    end
  end

  after :restart, :clear_cache do
    on roles(:web), in: :groups, limit: 3, wait: 10 do
      # Here we can do anything such as:
      within release_path do
        execute :rake, 'cache:clear'
      end
    end
  end
  after :finishing, 'deploy:cleanup'
end

I tried to included all necessary information, please let me know if there is anything else I can add, thanks for any help you can provide!

Answer 1

In Capistrano 3, you use repo_url instead of repository

So in your deploy.rb, try replacing

set :repository, "[email protected]:username/appname.git"  # Your clone URL

with

set :repo_url, "https://github.com/username/appname.git"  # Your clone URL

Hopefully this helps.

Update: The ssh URL needs a key; the https URL does not. It's worked for me.
