1. The first goal is to let user customize the base image of the component
by passing FROM=myimage during the build process. This would let any
project leveraging Airship ensure that the base image is matching the
security requirements for that project. This will also ease the control of
the /etc/apt/source.list and thereby the result of apt-get update/upgrade
procedure.
2. The above goal is achievable by using docker-ce feature such as:
ARG FROM="defaultbaseimage:xx"
FROM ${FROM}
For this reason, the installation of docker.io in the Zuul gating is beeing
replaced by docker-ce.
3. Third Goal is to bring consistency with the other compoenents leveraging
Helm such as the openstack-helm and potentially use bindep the same way
the LOCI images are to ensure
4. The new syntax in the Dockerfile is still commented out until the associated
image builder have been updated to use docker-ce as they have been for the LOCI
images.
