Question

here is my deployment.rb file.

# config valid only for current version of Capistrano
lock '3.4.0'

set :stage, 'production'
set :application, "gobgob-ror"
set :repo_url, '[email protected]:narhamah/gobgob-ror.git'
# Default branch is :master
# ask :branch, `git rev-parse --abbrev-ref HEAD`.chomp

# Default deploy_to directory is /var/www/my_app_name
set :deploy_to, '/home/ubuntu/gobgob-ror'

# Default value for :scm is :git
set :scm, :git
set :branch, "master"

#set :user, "ubuntu"
set :use_sudo, false
set :rails_env, "production"
set :deploy_via, :remote_cache
set :ssh_options, { user: 'ubuntu', :forward_agent => true, :port => 22, keys: ["#{ENV['HOME']}/.ssh/id_rsa"]}


# Default value for :format is :pretty
# set :format, :pretty

# Default value for :log_level is :debug
# set :log_level, :debug

# Default value for :pty is false
set :pty, true
server "xx.xx.xxx.xxx", roles: [:app, :web, :db], :primary => true

set :normalize_asset_timestamps, %{public/images public/javascripts public/stylesheets}
# Default value for :linked_files is []
set :linked_files, fetch(:linked_files, []).push('config/database.yml', 'config/secrets.yml')

# Default value for linked_dirs is []
set :linked_dirs, fetch(:linked_dirs, []).push('log', 'tmp/pids', 'tmp/cache', 'tmp/sockets', 'vendor/bundle', 'public/system')

# Default value for default_env is {}
# set :default_env, { path: "/opt/ruby/bin:$PATH" }

# Default value for keep_releases is 5
set :keep_releases, 5

namespace :deploy do
  desc "Start the application"
  task :start do
    on roles(:app) do
      execute "cd #{current_path} && RAILS_ENV=#{fetch(:stage)} bundle exec puma -b 'unix://#{shared_path}/sockets/puma.sock' -S #{shared_path}/sockets/puma.state --control 'unix://#{shared_path}/sockets/pumactl.sock' >> #{shared_path}/log/puma-#{fetch(:stage)}.log 2>&1 &", :pty => false
    end
  end

  desc "Stop the application"
  task :stop do
    on roles => :app  do
      execute "cd #{current_path} && RAILS_ENV=#{fetch(:stage)} bundle exec pumactl -S #{shared_path}/pids/puma.state stop"
    end
  end

  desc "Restart the application"
  task :restart do
    on roles(:app) do
      execute "cd #{current_path} && RAILS_ENV=#{fetch(:stage)} bundle exec pumactl -S #{shared_path}/pids/puma.state restart"
    end
  end

  desc "Status of the application"
  task :status do 
    on roles(:app) do
      execute "cd #{current_path} && RAILS_ENV=#{fetch(:stage)} bundle exec pumactl -S #{shared_path}/pids/puma.state stats"
    end
  end
end

after "deploy", "deploy:restart"
after "deploy", "deploy:cleanup"

Now I did bundle exec cap production deploy. And after huge log I got the below error.

Looks like the bundler gem is not installed on your server. It should be installed and the bundle executable should be available in $PATH.

Try executing the bundle --version directly on the server to ascertain that bundler is actually missing.

If that is case, install the bundler gem and you should be good to go. Or to actually keep things automated you can define a capistrano task to check if the bundle executable is available or not and install the bundler gem if it is not available. You can execute this task before the bundler:install task.

UPDATE : If you are using some ruby manager like rvm or chruby or anything like that, the bundle executable might not be available to your Capistrano deploy task. In that case you have to make sure your deploy task gets a login shell so that all those shell scripts are executed.
