How can I do SSH inside my instance in OpenStack

Question

Hi Guys,

I'm new in OpenStack. I launched an instance and attached key-pairs, still I'm not able to SSH in my instance. Generally, in AWS we have to create one key for SSH and we can remotely log in. But same thing is not working here. How to solve this problem?

Thank You

Hi@akhtar,

Yes, there is nothing wrong with your steps. But when you launch an instance in AWS, apart from key they do lots of thing internally. AWS assigns gateway, IP, security etc. Whereas in OpenStack the scenario is not the same. When you launch an instance in OpenStack, it will launch in Host Only Mode. So, you can ping or SSH to your instance if you are in the same Network or Router. I think that is the issue with your instance.

Now coming to the solution. You can add your VM's public ip with your instance. For that you can follow the below given steps.

$ ssh-keygen

$ cd .ssh

$ nova keypair-add –pub_key id_rsa.pub mykey

Hope this will help you.

Thank You
