SSH_AUTH_SOCKET не создан при развертывании с Capistrano

Question

Я развертываю приложение ruby на рельсах с Capistrano. Работает нормально, но у меня есть проблема, связанная с s sh -агентом. Затем net-ssh не проходит проверку подлинности.

, когда я печатаю значение ENV ['SSH_AUTH_SOCKET'] внутри моего ruby в журналах приложений rails, выполненных puma, я получаю следующее:

/tmp/ssh-wJBDegaQTF/agent.20252

Но этот файл не существует и net -s sh не удается:

ls -ld /tmp/ssh-*
drwx------ 2 deploy deploy 4096 févr. 26 21:50 /tmp/ssh-68VlKUx0U0
drwxr-xr-x 2 deploy deploy 4096 févr. 27 01:25 /tmp/ssh-agVZL13989

drwx------ 2 deploy deploy 4096 févr. 27 01:26 /tmp/ssh-wvbVUbRNF95O

, тогда я получаю эту проблему, когда эта строка выполняется:

Net::SSH.start('192.168.0.1', 'root', keys: ['/home/deploy/.ssh/id_rsa'], port: 2002, verbose: :debug) { |ssh| ssh.exec!('ls') }

если я запускаю ENV ['SSH_AUTH_SOCK'] на консоли с командой cap deploy rails:c, файл хорошо создан.
