Rails 4 + Capistrano 3：致命：部署时无法从远程存储库读取 [英] Rails 4 + Capistrano 3 : fatal: Could not read from remote repository while deploying

问题描述

使用Capistrano 3部署Rails 4应用程序时出现以下错误

$ b

这里是capistrano的配置。

config / deploy.rb

 ＃config仅对当前版本的Capistrano有效
 lock' 3.4.0'
 
 set：application，'magnificent'
 set：repo_url，'[e-mail]：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 /缓存tmp / sockets vendor / bundle public / system} 
 set：branch，'develop'＃set /：branch，`git rev-parse --abbrev-ref HEAD`.chomp 
 set：ssh_options， {forward_agent：true} 
 
名称空间：deploy do 
 
 desc'重新启动应用程序'
任务：重新启动
对角色（：app），in ：：sequence，wait：5 do 
 execute：touch，release_path.join（'tmp / restart.txt'）
 end 
 end 
 
 after：publishing， 'deploy：restart'
 after：finish，'deploy：cleanup'
 end 
 $ b namespace：deploy do 
 
 after：restart，：clear_cache do 
 on roles（：web ），在：：groups，limit：3，wait：10 do 
＃在这里，我们可以做任何事情，例如：
＃在release_path中执行
＃execute：rake，'cache：clear' 
＃end 
 end 
 end 
 
 end 
  

production.rb

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

< Capist

  require'capistrano / setup'
 require'capistrano / deploy' 
要求'capistrano / rvm'
要求'capistrano / bundler'
要求'capistrano / rails'
要求'capistrano / rails / assets'
要求'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回购，还有 GIT_ASKPASS = / bin / echo GIT_SSH = / tmp / magnificent / git-ssh.sh / usr / bin / env git ls-remote --heads [e-mail]：BoTreeConsultingTeam / magnificent.git 命令适用于远程服务器。

解决方案

< h3>当前解决方案

最近我使用了不同的解决方案。在 cap production deploy 之前运行以下命令。

1. eval$（ssh-agent -s）


2. ssh-add〜/ .ssh / id_rsa

以前的解决方案

我可以通过替换

  set：repo_url，'[e-mail]：BoTreeConsultingTeam / magnificent.git'
  
 
 
 $ p $  
  set：repo_url，' https：// my_github_username：[e-mail]/BoTreeConsultingTeam/magnificent'
  

注意如果你的密码包含特殊字符，那么它应该被url编码。您可以使用irb中的 URI :: encode 快速编码。

使用Capistrano 2进行其他部署时，我从不需要提供github证书。

任何人都可以告诉我为什么我必须在 repo_url 中指定git用户名/密码？

upcase论坛帖子也有效。

I am getting following error while deploying Rails 4 application using Capistrano 3

DEBUG [1ec94dd1]    and the repository exists.

Here is capistrano configuration.

config/deploy.rb

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

set :application, 'magnificent'
set :repo_url, '[e-mail]: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'

I also copied /home/deploy/.ssh/id_rsa.pub of remote server to github deploy keys.

UPDATE I confirm that I am able to access remote repo and also GIT_ASKPASS=/bin/echo GIT_SSH=/tmp/magnificent/git-ssh.sh /usr/bin/env git ls-remote --heads [e-mail]:BoTreeConsultingTeam/magnificent.git command works on remote server.

解决方案

Current Solution

Lately I use different solution. Before cap production deploy I run following commands.

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

Previous Solution

I am able to fix this issue by replacing

set :repo_url, '[e-mail]:BoTreeConsultingTeam/magnificent.git'

with

set :repo_url, 'https://my_github_username:[e-mail]/BoTreeConsultingTeam/magnificent'

Note if your password contains special characters then thet should be url encoded. You can quickly encode using URI::encode in irb.

With other deployments using Capistrano 2, I never need to supply github credentials.

Can anybody please tell why should I have to specify git username/password in repo_url?

There is one more solution in the upcase forum post which also worked.
