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.

Flavors define the compute, memory, and storage capacity of virtual machine. To put it simply, a flavor is an available hardware configuration for a server.

Authentication#

You can also create a private key for access to your server.

Networking#

The OpenStack Networking service provides an API that allows you to set up and define network connectivity and addressing in the cloud.

Connect to your server#

Cloudify Dashboard#

The server will appear in the Cloudify.ro dashboard within minutes of creation.
