Trying to set authorized keys based on ssh-keygen

[Nimon Ambient]

Hi guys,

I'm still new to vagrant and I'm trying to pull up a jenkins, svn instance and a couple of clients and that's all fine but I'm then trying to push the jenkins root ssh key out so it can connect to the other boxes pretty much straight away, and that's where I'm failing.

I'm trying to set a variable depending on the output of a cat inside the box and it doesn't work, the other boxes just get a blank authorized_keys. I'm sure there's a way to do this but I can't see it. I tried putting a "puts" at the end to print the variable but vagrant doesn't seem to run a puts like standard ruby would.

Here's my vagrantfile. I've bolded the non-working bits. Thanks in advance.

What you can do and is something like this:

j.vm.provision "shell", inline: "sudo cat /root/.ssh/id_rsa.pub >

/vagrant/j.id_rsa.pub"

That will create a copy of the pub rsa in the vagrant folder, that is
shared between all the gue4st and host

Then you can use

s.vm.provision "shell", inline: "sudo cat /vagrant/j.id_rsa.pub |
sudo tee -a /root/.ssh/authorized_keys"

sudo tee -a should be used instead of `>>`

sudo tee should be used instead of `>`

Hope this helps

Thankyou! Of course, I should have thought of /vagrant!!
