Развертывание приложений Rails 4 с использованием mina на webfaction

Question

У меня есть приложение rails 4, которое я пытаюсь развернуть на webfaction. Приложение находится на битбакете. Кроме того, в соответствии с документами webfaction приложение должно быть развернуто в пути «/ home/username/webapps/app». У меня есть вся моя настройка database.yml (для всех envs) в secrets.yml, которая была скопирована в shared_path/config.

В соответствии с указанной в документации http://docs.webfaction.com/software/rails.html должны быть заданы некоторые переменные среды. Webfaction вам нужно установить переменные env, которые будут уничтожены после завершения сеанса ssh. Я попытался установить их в задаче set_env_variables.

структура каталога как:

$ pwd 
/home/username/webapps/appname 
$ ls 
bin gems hello_world lib nginx releases scm shared src tmp 
$ls gems/ 
bin build_info cache doc extensions gems specifications 
$ ls gems/gems/ 
actionmailer-4.1.8   bundler-1.7.9    jbuilder-2.2.5  rack-test-0.6.2  sass-rails-4.0.5  tilt-1.4.1 ... 
$ cd hello_world/ 
[hello_world]$ bundle 
-bash: bundle: command not found 
$ cd .. 
$ pwd 
/home/username/webapps/appname 
$ export PATH=$PWD/bin:$PATH 
$ export GEM_HOME=$PWD/gems 
$ export RUBYLIB=$PWD/lib 
$ cd hello_world/ 
$ bundle 
Using rake 10.4.2 
... 
Your bundle is complete! 
Use `bundle show [gemname]` to see where a bundled gem is installed. 

Он указывает, что нам нужно установить переменные окр.

Здесь 'hello_world' представляет собой пример рельсов, созданный webfaction. Я бы удалил его. Также предусмотрены nginx-пассажиры. Мой сценарий развертывания в

require 'mina/bundler' 
require 'mina/rails' 
require 'mina/git' 

set :domain, 'webabc.webfaction.com' 
set :deploy_to, '/home/username/webapps/appname' 
set :repository, 'git@bitbucket.org:username/appname.git' 
set :branch, 'master' 

set :shared_paths, ['config/secrets.yml', 'log', 'tmp'] 
set :user, 'ssh-username' # Username in the server to SSH to. 

task :environment do 
end 

task :setup => :environment do 
    queue! %[mkdir -p "#{deploy_to}/#{shared_path}/tmp"] 
    queue! %[chmod g+rx,u+rwx "#{deploy_to}/#{shared_path}/tmp"] 

    queue! %[mkdir -p "#{deploy_to}/#{shared_path}/log"] 
    queue! %[chmod g+rx,u+rwx "#{deploy_to}/#{shared_path}/log"] 

    queue! %[mkdir -p "#{deploy_to}/#{shared_path}/config"] 
    queue! %[chmod g+rx,u+rwx "#{deploy_to}/#{shared_path}/config"] 

    queue! %[touch "#{deploy_to}/#{shared_path}/config/secrets.yml"] 
    queue %[echo "-----> Be sure to edit '#{deploy_to}/#{shared_path}/config/secrets.yml'."] 
end 

desc "Deploys the current version to the server." 
task :deploy => :environment do 
    deploy do 
    invoke :'set_env_variables' 
    invoke :'git:clone' 
    invoke :'deploy:link_shared_paths' 
    invoke :'bundle:install' 
    invoke :'rails:db_migrate' 
    invoke :'rails:assets_precompile' 
    invoke :'deploy:cleanup' 

    to :launch do 
     queue "mkdir -p #{deploy_to}/#{current_path}/tmp/" 
     queue "touch #{deploy_to}/#{current_path}/tmp/restart.txt" 
     invoke :restart 
    end 
    end 
end 

desc "Set the environment variables." 
task :set_env_variables => :environment do 
    queue! "cd /home/username/webapps/appname" 
    queue! "export GEM_HOME=$PWD/gems" 
    queue! "export RUBYLIB=$PWD/lib" 
    queue! "export PATH=$PWD/bin:$PATH" 
    queue! "export LD_LIBRARY_PATH=$HOME/lib/" 
end 

Когда я 'Mina развернуть --verbose --trace', я получаю

Ссылка https://community.webfaction.com/questions/5186/capistrano-cant-find-bundle определяет решение для сценария развертывания Capistrano. Как я могу исправить это для мины?

Answer 1

Вместо использования :set_env_variables задач, попробуйте добавить переменную :bundle_bin с параметрами ENV:

set :bundle_bin, %{PATH="#{deploy_to}/bin:$PATH" GEM_HOME="#{deploy_to}/gems" RUBYLIB="#{deploy_to}/lib" RAILS_ENV=#{env} #{deploy_to}/bin/bundle} 

Таким образом Mina использует правильные переменный каждый раз, когда он использует команду bundle. Я думаю, что добавление его в качестве задачи и просто экспорт переменных заставляет их забыть. Заказ может быть проблемой.
