通过Capistrano通过Jenkins部署 - SSH身份验证失败

Question

我有一个运行Capistrano部署的Jenkins构建作为后构建操作.

从控制台运行Capkinsrano任务作为Jenkins用户工作非常正常,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(或许Net::SSH::AuthenticationFailed: not-specified)时不会选择我的SSH密钥？

有谁知道这里可能出了什么问题？

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

希望这对你有用!贝壳很烦人.
