Question

我有一个运行Capistrano部署的Jenkins构建作为构建后的动作。

从控制台运行Capkinsrano任务作为Jenkins用户非常正常，没有密码提示（我之前在构建和登台服务器上都设置了SSH密钥）。但是，当通过Jenkins运行相同的脚本时，我突然收到密码提示，然后构建失败（没有TTY存在）。

看起来Ruby在运行Jenkins时可能不会选择我的SSH密钥（Net::SSH::AuthenticationFailed: not-specified）？

有没有人知道这里可能出现的问题？

我们遇到了类似的事情。 jenkins的登录shell可能已经自动运行了ssh代理，但jenkins为您的部署生成的上下文却没有。

尝试在jenkins脚本中手动启动一个：

# Start the ssh agent. Evaling the output will set the relevant environment 
# variables
eval `ssh-agent` 

# Add the default keys like id_rsa and id_dsa (or explicitly specify your key,
# if it's not a default)
ssh-add

# Your normal deploy script here

# Save the return value of your script
RETVAL=$?

# Clean up
kill $SSH_AGENT_PID

# Exit the script with the true return value instead of the return value of kill
# which could be successful even when the capistrano portion of the build has
# crashed
exit $RETVAL

希望这适合你！贝壳很烦人。

很遗憾，我只是在执行deploy.rb之前替换了原始cap deploy，而在我添加set :password, "sshpassword"

的本地保存的另一个{{1}}

通过Capistrano通过Jenkins部署 - SSH身份验证失败
