It should be a simple question.
I had a vagrant box there, where I can start vagrant ssh to access it without password.
And how can I remotely execute ssh command to get some result like below, which can be used in jenkins CI server to check something.
$ vagrant ssh 'who -a'
My environment
The following should work; for more information check out man vagrant, man ssh and man who.
vagrant ssh -c "who -a"
You could also use the following to see the ssh config behind the vagrant ssh command:
vagrant ssh-config
Note: This will only work once you did vagrant up.
Then use the ip, port, key, etc. in your own ssh command:
ssh -i /path/to/vagrant/keyfile vagrant@ip:port who -a
To execute complex commands in Jenkins i prefer the following syntax
vagrant ssh -- who -a
where everything after the '--' is passed as a command to the VM's shell.
From http://docs.vagrantup.com/v2/cli/ssh.html:
If a -- (two hyphens) are found on the command line, any arguments after this are passed directly into the ssh executable.
