How to ssh to vagrant without actually running "vagrant ssh"?

I would like to reproduce the way Vagrant logs in to my VM within a shell script using an ssh command, so I create an alias to my Vagrant instance.

What is the command syntax to use the regular ssh command to access it?

Solution 1:

There's a lot of answers already, but they all seem overly complicated or solve problems the asker didn't have.

simply:

# save the config to a file
vagrant ssh-config > vagrant-ssh

# run ssh with the file.
ssh -F vagrant-ssh default

Solution 2:

I've had to re-implement "vagrant ssh" because it's -c option didn't pass on arguments properly. This is basically what it does (there might be more, but it works fine this way)

#!/bin/sh
PORT=$(vagrant ssh-config | grep Port | grep -o '[0-9]\+')
ssh -q \
    -o UserKnownHostsFile=/dev/null \
    -o StrictHostKeyChecking=no \
    -i ~/.vagrant.d/insecure_private_key \
    vagrant@localhost \
    -p $PORT \
    "$@"

As a one-liner (with thanks to kgadek):

ssh $(vagrant ssh-config | awk 'NR>1 {print " -o "$1"="$2}') localhost

To account for when you have more than one vagrant host, this will select the desired host, as well as cull blank lines from the config (using sed):

HOST=name-of-my-host
ssh $(vagrant ssh-config $HOST | sed '/^[[:space:]]*$/d' |  awk 'NR>1 {print " -o "$1"="$2}') localhost
