OpenStack DevStack development

Making changes to the deployed components

Enabling cinder-backup

Add the following to your local.conf to enable cinder-backup followed by a redeployment:

# Cinder backup (will use Swift per default, otherwise $CINDER_BACKUP_DRIVER)

OpenStack Standardized Image Encryption - Manual DevStack Testing

The below instructions are manual steps to validate the implementation of the Standardized Image Encryption on a DevStack as per upstream patchsets uploaded at https://review.opendev.org/q/topic:%22LUKS-image-encryption%22

For further information see the corresponding Glance Spec and Cinder Spec.

Note: the instructions were created during the implementation phase of the patchsets and details about the process of using image encryption might change in the future and may not reflect the behavior of stable OpenStack releases.

DevStack within an OpenStack VM (all-in-one)

Host VM on OpenStack

openstack volume create --size 200 --image "Ubuntu 22.04 LTS x64" devstack-boot-volume

openstack security group create devstack-sg

Minimal DevStack VirtualBox setup

This is a very concise quickstart guide to setup an OpenStack DevStack limited to Keystone in a VirtualBox VM using Ubuntu Server LTS as the guest operating system. By limiting the DevStack to primarily deploy Keystone only, installation is quick and the machine does not take up much resources.

As the time of writing it uses up about 11 GB of disk space and 1 GB of RAM running Keystone.

This is meant for testing authentication and IDM-related things with OpenStack Keystone while disregarding other components. It can easily be extended by further components by adjusting the local.conf accordingly.
