Launch and Access Your Instance

Creating a Virtual Machine

Create and launch a VM OpenStack Command

The Jetstream team makes *** Featured- **
images available from which to build.		 openstack image list
Create and boot an instance
Notes:

  • Make sure your SSH keyname matches
  • your-instance-name is the name of the
    instance; make it something meaningful for you.
  • Choose an appropriate flavor from the list in the
    first command
  • Choose an appropriate image from the list in the
    second command
 openstack server create <my-server-name> \
--flavor FLAVOR \
--image IMAGE-NAME \
--key-name <my-keypair-name> \
--security-group <my-security-group-name> \
--wait
Optional-Volume-backed

Add the following optional flag to the above
server create step if you wish to not use the
default ephemeral disk and instead
create a custom volume-backed instance
(storage counts against your quota)

  • size in GB
  • Note your volumes_attached id from the server create output
--boot-from-volume <size>

Optional Rename volume:

openstack volume set --name '<my-server-name>-vol' <volumes_attached_id>
Optional-Network

If you have multiple networks, you’ll need
to also include this line in the
server create step

See Create a network in the CLI for more
information
--nic net-id=<my-network-name>
Create a public IP address for an instance openstack floating ip create public
Add that public IP address with that instance openstack server add floating ip my-server-name your.ip.number.here

Logging into your Virtual Machine

Once your instance is up and has a floating IP, you are ready to ssh in and use it. If your ssh key is one of the default names (e.g. id_rsa or id_ed25519) and is in your ~/.ssh dir, you won’t need to specify the location of the key. Otherwise, you’ll need to use the ssh option -i path/key. For example:

ssh -i ~/.ssh/my-custom-key-name user@ip.number

Each distribution has a different default user. We will show examples for each without the -i path to your ssh key, assuming you have ~/.ssh/id_rsa or ~/.ssh/id_ed25519 as your default key:

For Ubuntu 20 or 22:

ssh ubuntu@your.ip.number.here

For Rocky 8/9:

ssh rocky@your.ip.number.here

You should be able to access and use your VM now! Please see Instance Management Actions in the CLI for all instance management actions.
