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

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, "git@github.com: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

In Capistrano 3, you use repo_url instead of repository

So in your deploy.rb, try replacing

set :repository, "git@github.com: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.
