Configuring Cinder volume services

In this recipe, we will use Openstack-Ansible to deploy the Cinder service. We assume that your environment has been deployed using the recipes described in Chapter 1, Installing OpenStack with Ansible.

Getting ready

To use Cinder volumes with LVM and iSCSI, you will need a host (or hosts) running Ubuntu 16.04. Additionally, you will need to ensure the volume hosts are manageable by your Openstack-Ansible deployment host.

The following is required:

• An openrc file with appropriate credentials for the environment

• Access to the openstack-ansible deployment host

• A dedicated server to provide Cinder volumes to instances:

  • An LVM volume group, specifically named cinder-volumes

  • An IP address accessible from the deployment host

If you are using the lab environment that accompanies this book, cinder-volume is deployed to a host with the following details:

• cinder-volume API service host IP: 172.29.236.10

• cinder-volume service host IP: OpenStack management calls over 172...
