With OpenStack, instances, or virtual machines, play a large role in a cloud's workload. OpenStack provides a way to create and manage instances with its compute service, called Nova.In this guide, we cover the preparatory steps required to create an instance, including setting up a private network and router, creating a security group, and how to add an SSH key pair.To check that the SSH key was correctly added to sammy on the provisioned Droplets, connect to one of them with the following command: ssh-i private_key_location [email protected]_ip_address; Remember to put in the private key location and the IP address of one of the provisioned Droplets, which you can find in your Terraform output.Generally speaking, when launching instances in a cloud environment (such as AWS or an OpenStack-based cloud), the preferred/default way of accessing that instance is via SSH using an injected SSH key pair. There are times, though, when—for whatever reason—this approach won't work. (I'll describe one such situation below.)Creates a server and assigns a floating IP. parameters: key_name: type: string. description: Name of an existing key pair to use for the instances. constraints: - custom_constraint: nova.keypair. description: Must name a public key (pair) known to Nova.Installing DevStack Controller.
