指定专用SSH密钥执行带或不带红宝石shell命令时使用? [英] Specify private SSH-key to use when executing shell command with or without Ruby?
问题描述
一个相当不寻常的情况也许是,但我想指定专用SSH密钥从本地计算机执行外壳(GIT)命令时使用。
A rather unusual situation perhaps, but I want to specify a private SSH-key to use when executing a shell (git) command from the local computer.
基本上是这样的: git的克隆git@github.com:TheUser / TheProject.git - 键/家/克里斯托弗/ ssh_keys / theuser
甚至更好(在Ruby中):
Or even better (in Ruby):
with_key("/home/christoffer/ssh_keys/theuser") do
sh("git clone git@github.com:TheUser/TheProject.git")
end
我看到连接到与净::使用指定私钥SSH远程服务器的例子,但是这是一个本地命令。这可能吗?
I have seen examples of connecting to a remote server with Net::SSH that uses a specified private key, but this is a local command. Is it possible?
推荐答案
这样的事情应该工作:
ssh-agent $(ssh-add /home/christoffer/ssh_keys/theuser; git clone git@github.com:TheUser/TheProject.git)
或由orip建议:
ssh-agent bash -c 'ssh-add /home/christoffer/ssh_keys/theuser; git clone git@github.com:TheUser/TheProject.git'
git会调用SSH将找到环境变量,其代理;这将反过来,有钥匙装入。
git will invoke ssh which will find its agent by environment variable; this will, in turn, have the key loaded.
另外,设为主页也可能会做的伎俩,只要你愿意建立一个只包含一个.ssh目录为HOME目录;这可能既包含identity.pub,或配置文件设置IdentityFile。
Alternatively, setting HOME may also do the trick, provided you are willing to setup a directory that contains only a .ssh directory as HOME; this may either contain an identity.pub, or a config file setting IdentityFile.
