To create a server we need to specify what flavor (the specifications of your cloud instance), networks and image we’ll be using
To request a we can use openstack flavor list
$ openstack flavor list

Images can similarly be listed
$ openstack image list --limit 2

+-----------------------------+-----------------+------------------------------+We now have all the information we need to create our first server!
$ openstack server create "our first server" --flavor xer.small --image c38664dc-0299-4a4b-b0d4-fb48552e68fb --network "Public Guam"

+-----------------------------+-------------------------------------------------------------+Note: By default, the default security policy is egress only. To enable ingress, create a new security group with the required rules.
We’ll receive the details of our server and that it’s in the BUILD state.
Lets check in on how it’s progressing:
