Enhancement: Authentication Should Support ssh config file

[darkn3rd]

For ssh support, I wish I could use ssh-configuration file. Vagrant is one use case I would use this:

vagrant ssh-config > ssh-config
bolt command run $command -F ssh-config web-01.dev

Net::SSH::Config support this with load method:

This should be working already. If not, there might be a bug. What are you trying to use in the ssh config and what isn't working?

I don't see an option for this:

Ah yes, it's done automatically and only uses the default ssh-config file. We certainly could add the option to specify a different ssh-config.

Vagrant users would be very happy. I dynamically generate these for my own bootstrap process in dev environments using vagrant, google cloud, or AWS. I can cat them to my ~/.ssh/config, but then it would be difficult to rip them out (instr + gsub hackery) when I remove the boxes.

If you have SSH > 7.3, you can use the Include directive in ssh-config. So you could add something like Include config.d/* and write your environment-specific files to ~/.ssh/config.d/<filename>. That's a workaround, but it seems like it might work, if the version of SSH supports it.

My local development environment doesn't have it (Ubuntu 16.04)

$ lsb_release -cs
xenial
$ ssh -V
OpenSSH_7.2p2 Ubuntu-4ubuntu2.4, OpenSSL 1.0.2g  1 Mar 2016

A lot of systems out there, run Ubuntu 14.04, such as bastion host workstation.
