Capistrano 3.0 - 如何安全地提示输入密码？ [英] Capistrano 3.0 — How securely prompt for password now?

问题描述

在 3.0 之前，有一种方法可以做到这一点：

Prior to 3.0 there was a way to do that:

# ...
set :mysql_password, proc { Capistrano::CLI.password_prompt "Gimme remote database server password. Don't worry, I won't tell anyone: " }
# ...

namespace :db do
  desc 'Dump remote database'
  task :dump do
    run "mysqldump -u #{mysql_user} -p #{mysql_database} > ~/#{mysql_database}.sql" do |channel, stream, data|
      if data =~ /^Enter password:/
        channel.send_data "#{mysql_password}\n"
      end
    end
  end
end

它提示输入密码，不会在您键入时显示，也不会在其中留下痕迹日志和输出。

It prompts for password, doesn't show it as you type and leaves no traces of it in the logs and the output.

现在，截至 3.0 是我找到的唯一方法：

Now, as of 3.0 the only way I have found:

# ...

namespace :db do
  desc 'Dump remote database'
  task :dump do
    ask :mysql_password, nil
    on roles(:db) do
      execute "mysqldump -u#{fetch :mysql_user} -p#{fetch :mysql_password} #{fetch :mysql_database} > ~/#{fetch :mysql_database}.sql"
    end
  end
end

它做的工作，但显示密码无处不在。

It does the job but reveals password everywhere.

有没有人找到一个安全的方式密码提示在 3.0 ？谢谢！

Have anyone found a secure way for password prompting in 3.0? Thanks!

推荐答案

# Capistrano >= 3.3.3 supports `echo: false`
ask :password, 'default', echo: false
server 'server.domain.com', user: 'ssh_user_name', port: 22, password: fetch(:password), roles: %w{web app db}
