Creating an instance with ssh key pair
Hello all,
If I create an instance providing ssh key pair while creation, and using a
"normal template" from the cloudstack setup, then will the SSH to vm using
the keyPairFlieLocation always work?
Or the template which I am using for creating the instance has to be
supporting SSH keys? as explained in 5.2.1 section at
http://cloudstack.apache.org/docs/en-US/Apache_CloudStack/4.0.2/html/Installation_Guide/using-sshkeys.html
In short, Is the SSH using keyPairFileLocation - template dependent or
will it always work if I provide ssh key pair while creating instance and
use normal template?
Regards,
Gaurav

Hi Gaurav,
SSH to vm using keyPairFileLocation is template dependent .ie. template must have the script as mentioned in the doc.
Thanks,
Sanjeev

SSH script pulls only the ssh public key that is associated with the vm instance.
There is an API to reset the SSH key pair associated to the VM. This is will associate new ssh key pair to the vm and on reboot of vm this ssh script gets the new ssh public key into the VM.
If you can modify the ssh script in the vm to append the new ssh public key to the authorised_keys file we can use both old and new ssh key pair.

Will this only pull down one key pair or can it pull down many? We have a need to pull in our keys as well as all of our customers keys.
If the script can only pull down one, we can make it work, but would be nice to pull down all keys from the project an instance is associated with.

To deploy Vm using ssh key pairs you will need to use a template that has SSH Key Gen Scripts in it.
Only then you will be able to ssh into the instance using ssh key.
