Question

我正在使用mina来部署我的应用程序。我指定了我想部署应用程序的env（登台/制作）。

mina deploy on=staging --verbose

我已将deploy.rb中的app env保存为

app_env = ENV['on'] || 'staging'

我有一个需要生产数据库备份的rake任务。截至目前，我在我的控制台上明确地运行了rake任务

bundle exec rake deploy:backup_prod_db --trace

我想在每个生产部署上运行该任务。我该怎么做？

Answer 1

mina有特殊的语法。从mina控制台帮助页面：

Server tasks:
  ...
  mina rails[arguments]   # Execute a Rails command in the current deploy
  mina rake[arguments]    # Execute a Rake command in the current deploy
  mina run[command]       # Runs a command in the server
  ...

所以从命令行：

$ mina 'rake[deploy:backup_db]'

或者在mina deploy配置文件（config/deploy.rb）中定义任务：

task :backup_db do
  invoke :'rake[deploy:backup_db]'
end

Answer 2

让它运转起来。变化是

...
app_env = ENV['on'] || 'staging'
...

desc "Deploys the current version to the server."
task :deploy => :environment do
  deploy do
    # Put things that will set up an empty directory into a fully set-up
    # instance of your project.
    invoke 'production_backup' if app_env == 'production'
    invoke :'git:clone'
    invoke :'deploy:link_shared_paths'
    invoke :'bundle:install'
    invoke :'rails:assets_precompile'

    to :launch do
      invoke 'application:restart'
    end
  end
end

task :production_backup do
  queue "cd #{deploy_to}/current ; bundle exec rake deploy:backup_db"
end

如何从mina部署脚本运行自定义rake任务
