Registered by Gema Gomez

This blueprint is meant to track the work required for the creation of ARM64 containers for OpenStack and the multiarch work required to make this happen sanely.

Whiteboard

Tasks roughly identified as necessary:
- Debian containers are not up to date nor in a working state. They need to be worked on and brought up to a working state so that they can be used on ARM64.
-- 124 containers built, 84 failed
- Identify all the changes that need to be done so that more than one architecture can coexist and the
right containers are chosen depending on the arch.
-- https://review.openstack.org/#/c/430940 adds non-x86 support
- Bring up 3rd party CI with ARM64 hardware to be able to validate the ARM64 containers: 3rd party CI continues to be worked on but won't land during Pike. We are aiming at landing this on Queens (see https://blueprints.launchpad.net/kolla/+spec/aarch64-3rd-party-ci-kolla).

Waiting for Ocata release (10th March) to get reviewers ready to look at patches.
