Server quick start
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 list of available flavors we can use openstack flavor list
$ openstack flavor list
+-------------------+-------------+--------+------+-----------+-------+-----------+
| ID | Name | RAM | Disk | Ephemeral | VCPUs | Is Public |

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

+-----------------------------+-----------------+------------------------------+Creating your first server
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.
You can learn more about creating security groups in the Official OpenStack Documentation.
We’ll receive the details of our server and that it’s in the BUILD state.
Lets check in on how it’s progressing:
