Vagrant user's pub ssh key location?

[Makrand]

Hello All,

Where excatly is public key (which is stored in authorized key under .ssh in vagrant launched VM) for vagrant user is stored on the localhost? 

I can see below for an example VM

makrand@mint-gl63:~/vagrant_ssd/ubuntu18/.vagrant/machines/ubuntu-rke/virtualbox$ pwd

/home/makrand/vagrant_ssd/ubuntu18/.vagrant/machines/ubuntu-rke/virtualbox

makrand@mint-gl63:~/vagrant_ssd/ubuntu18/.vagrant/machines/ubuntu-rke/virtualbox$ ls -l

total 76

-rw-rw-r-- 1 makrand makrand    40 Jun  7 16:05 action_provision

-rw-rw-r-- 1 makrand makrand    10 Jun  8 11:19 action_set_name

-rw-rw-r-- 1 makrand makrand   148 Jun  8 11:19 box_meta

-rw-rw-r-- 1 makrand makrand     4 Jun  7 16:04 creator_uid

-rw-rw-r-- 1 makrand makrand    36 Jun  7 16:04 id

-rw-rw-r-- 1 makrand makrand    32 Jun  7 16:04 index_uuid

-rw------- 1 makrand makrand  1679 Jun  7 16:05 private_key

-rw-rw-r-- 1 makrand makrand   138 Jun  8 11:19 synced_folders

-rw------- 1 makrand makrand 40455 Jun  8 11:19 ubuntu-bionic-18.04-cloudimg-console.log

-rw-rw-r-- 1 makrand makrand    34 Jun  7 16:04 vagrant_cwd

I am wondering how does public is set into .ssh folder onto VM? Is it created on fly against above private key each time VM is provisioned? 

I am asking this because - I am setting up RKE (Rancher Kubernetes Engine) on single vagrant launched VM. While I am building the config to launch K8 clsuter....it is asking me to set  - SSH Private Key Path of host

Normally for setting up the passwordless login - one generates both pub and private key & then moves pub key from localhost to deisnation machine. I don't see

hello

you can use vagrant ssh-config to see the keys that can be used to login

hope this helps

Hi,

As stated in 1st post....I already know its using private key under .vagrant DIR.

/home/makrand/vagrant_ssd/devops-vm1/.vagrant/machines/devops-vm1/virtualbox/private_key

My question is - If I go to VM created with vagrant, I see public key in /home/vagrant/.ssh/authorized_keys

vagrant@devops-vm1:~$ cat .ssh/authorized_keys
ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDF5o67xfl3llu/+lJK3X4Jn7E0BuVWDxxWjHaaWcUXguz8JeuIdZp0HEhv/5RS39v126YWnCCuUvzbrqMSl7/oG3l9IouyqCpSEmKDP32+FzEtPkMJqUi0KoQ6Jc1DurvOwexTeYNkxzOrREyxxNGjrFDnW5MQMIXaDHaRMRHTYT12dIlKNb0ptdszgdC4svmeFomNcfLsO/AwODIYk4FXjN4fLHwPBBJ3vAaeDnPlIf0OOFhE/JEQ7h4mYbZlySRZQYCN/QXvdMY7rkYw78lb0SQF+mtbVL3s3hJvfN0Xig+vj859inL/nQwmQ/Ye+2nv5wodfpivx7z/2frpojH3 vagrant

how is this public key generated? I've checked few VMs and in each there is different public key authorized_keys.

Hi there,

Vagrant boxes are usually packaged with a default "insecure" keypair (https://github.com/hashicorp/vagrant/tree/master/keys) so that Vagrant can SSH in on first boot. Vagrant will then generate a unique keypair and replace the public key in authorized_keys.

Hope this helps!

Jeff
