卡皮斯特拉诺 3 : How to store git revision into a file?

Question

有没有办法从 Capistrano 3 获取 git 修订版本变量？

我不知道如何访问 capistrano 变量:

namespace :deploy do

  after :finished, :set_current_version do
    on roles(:app) do
      # dump current git version
      within release_path do
        execute :echo, "#{fetch(:revision_log_message)} >> public/version"
      end
    end
  end
end

Answer 1

这个有效

  after :finished, :set_current_version do
    on roles(:app) do
      # dump current git version
      within release_path do
        execute :echo, "#{capture("cd #{repo_path} && git rev-parse --short HEAD")} >> public/version"
      end
    end
  end
