A keypair is basically a ssh key allowing you to login to your virtual machine
Keypair options Keypairs provide the method to authenticate when logging into a Linux VM. There are several options for how to create them.
Assuming your existing ssh public key is located at ~/.ssh/ssh_my_rsa_key.pub
Import it using the following command:
openstack keypair create --public-key ~/.ssh/ssh_my_rsa_key.pub mykeypair
