Create Server
Openstack supports creating virtual machines from command line interface(CLI).
Requirements#
Openstack Server Create#
To create the server we need the following command that receives the parameters below:
openstack server create (--image <image> | --volume <volume>) --flavor <flavor> [--security-group <security-group>] [--key-name <key-name>] [--property <key=value>] [--file <dest-filename=source-filename>] [--user-data <user-data>] [--availability-zone <zone-name>] [--block-device-mapping <dev-name=mapping>] [--nic <net-id=net-uuid,v4-fixed-ip=ip-addr,v6-fixed-ip=ip-addr,port-id=port-uuid,auto,none>] [--network <network>] [--port <port>] [--hint <key=value>] [--config-drive <config-drive-volume>|True] [--min <count>] [--max <count>] [--wait] <server-name>All parameters are explained here #server-create
Listing flavors and images#
A virtual machine image is a single file which contains a virtual disk that has a bootable operating system installed on it.

To put it simply, a flavor is an available hardware configuration for a server.
