Rails 4 + Capistrano 3:致命:部署时无法从远程存储库读取

Question

我在使用Capistrano 3部署Rails 4应用程序时遇到以下错误

INFO [87512eb8] Running /usr/bin/env chmod +x /tmp/magnificent/git-ssh.sh as deploy@104.236.6.180

DEBUG [1ec94dd1]    and the repository exists.

这是capistrano配置.

配置/ deploy.rb

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

set :application, 'magnificent'
set :repo_url, 'git@github.com:BoTreeConsultingTeam/magnificent.git'
set :deploy_to, '/home/deploy/magnificent'

set :linked_files, %w{config/database.yml config/secrets.yml}
set :linked_dirs, %w{bin log tmp/pids tmp/cache tmp/sockets vendor/bundle public/system}
set :branch, 'develop' #set/ :branch,`git rev-parse --abbrev-ref HEAD`.chomp
set :ssh_options, { forward_agent: true }

namespace :deploy do

  desc 'Restart application'
  task :restart do
    on roles(:app), in: :sequence, wait: 5 do
      execute :touch, release_path.join('tmp/restart.txt')
    end
  end

  after :publishing, 'deploy:restart'
  after :finishing, 'deploy:cleanup'
end

namespace :deploy do

  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

end

production.rb

set :stage, :production
server 'xx.xx.xx.xx', user: 'deploy', roles: %w{web app}

Capfile

require 'capistrano/setup'
require 'capistrano/deploy'
require 'capistrano/rvm'
require 'capistrano/bundler'
require 'capistrano/rails'
require 'capistrano/rails/assets'
require 'capistrano/rails/migrations'
Dir.glob('lib/capistrano/tasks/*.rake').each { |r| import r }
set :rvm_type, :user
set :rvm_ruby_version, '2.2.2'

我还将远程服务器的/home/deploy/.ssh/id_rsa.pub复制到github部署密钥.

更新 我确认我能够访问远程repo并且GIT_ASKPASS=/bin/echo GIT_SSH=/tmp/magnificent/git-ssh.sh /usr/bin/env git ls-remote --heads git@github.com:BoTreeConsultingTeam/magnificent.git命令也 可以在远程服务器上运行.

现行解决方案

最近我使用不同的解决方案.在cap production deploy我运行以下命令之前.

1. eval "$(ssh-agent -s)"
2. ssh-add ~/.ssh/id_rsa

以前的方案

我可以通过替换来解决这个问题

set :repo_url, 'git@github.com:BoTreeConsultingTeam/magnificent.git'

同

set :repo_url, 'https://my_github_username:my_github_password@github.com/BoTreeConsultingTeam/magnificent'

请注意,如果您的密码包含特殊字符,那么它应该是url编码的.您可以使用URI::encodeirb 快速编码.

通过使用Capistrano 2的其他部署,我永远不需要提供github凭据.

任何人都可以告诉我为什么要指定git用户名/密码repo_url？

在upcase论坛帖子中还有一个解决方案也有效.
