Creating a flavor

When we boot a compute instance, we provide a flavor as a parameter. A flavor defines the resources of a compute instance, such as CPU, memory, and storage. On the Pike release of OpenStack, the default flavors are set as follows:

Flavor	VCPUs	Disk (in GB)	RAM (in MB)
m1.tiny	1	1	512
m1.small	1	20	2048
m1.medium	2	40	4096
m1.large	4	80	8192
m1.xlarge	8	160	16384

However, in many cases, the default flavors are not suitable for our needs.

How to do it...

OpenStack lets us create our own flavors, as follows:

- name: Create a custom flavor
  os_nova_flavor:
    name: custom1
    ram: 1024
    vcpus: 1
    disk: 10
    ephemeral: 10
    state: present
