Capistrano部署時出現以下錯誤

Question

部署時出現以下錯誤

DEBUG[c3b88189] Running /usr/bin/env [ -f /home/ubuntu/apps/stag/shared/config/database.yml ] on **.***.***.**
DEBUG[c3b88189] Command: [ -f /home/ubuntu/apps/
stag/shared/config/database.yml ]
DEBUG[c3b88189] Finished in 0.579 seconds with exit status 1 (failed).
ERROR linked file /home/ubuntu/apps/stag/shared/config/database.yml does not exist on **.***.***.**

SSHKit::Runner::ExecuteError: Exception while executing on host **.***.***.**: exit

SystemExit: exit

Tasks: TOP => deploy:check:linked_files
(See full trace by running task with --trace)
The deploy has failed with an error: Exception while executing on host 

如何糾正呢？

Answer 1

remote_file任務允許將遠程文件的存在設置為先決條件。 如果需要，這些任務又可以依賴於本地文件。

namespace :deploy do
  namespace :check do
    task :linked_files => 'config/database.yml'
  end
end

remote_file 'config/database.yml' => '/local/database.yml'
