Several people over the liberty cycle committed to maintaining
compose, but it was never completed. Rather than carry compose
in our repoistory until the end of time in a broken state I propose
removing it. If someone comes along and wants to resseruct the code
and make it functional in the future, I'd be 100% open to merge a
patch in the future which reintroduces this functionality. In the
meantime it is confusing to users which ask me on a daily basis if
compose is supported which I have to go into a 10 minute monologue
about why its in the repository.
Fortunately git contains full history so we can always revert this
change at a later time if someone wants to actually fixt his code
base up and make it useable in some way. I think the proper answer
is a seperate repoistory (kolla-compose) which contains any compose
related bits.
Please consider removing since nobody is using this code and its
dead.

Remove all data containers from the repository except the one image
we intend to reuse for each data container. Adjust compose files to
remove all references to the unique data containers which serve no
purpose other then to take up extra resources.
Needs VOLUME in data containers exported in the compose files.

This patch adds the docker-compose files, updates the docs,
and adds cinder to the start command.

We have to overlay the /lib/modules folder from the host to properly
`modprobe` from within a container. We don't have to give it write
permissions however, so the docker-compose volume is mounted in as 'ro'

A data volume container is far superior to bind mounting the
host's shared directories. It preserves the idempotency,
immutability and declarative properties of the containers.
The way this works in practice is that a data volume container is
created. Then when the containers start they use LVM to access
the filesystem where /var/lib/docker is contained. Then the
container startup logic bindmounts the data volume stored on the
host filesystem in /var/lib/docker/vfs/dir/ID. This prevents
people with access to the host operating system from damaging
the contents of the data container.
It does mean that now we must use tools/stop to stop our containers
rather than tools/cleanup-containers -f.
This is a containers best practice. For more details see:
https://docs.docker.com/userguide/dockervolumes/
Big credit goes to Danyeon Hansen for seeding this idea in the
mariadb containers.
Note occasionally docker-compose start/stop seems to not want to stop
a container. This bug needs to be addressed upstream separately
from our utilization of this best practice.

Previously, the nwfilter daemon/conf pkgs would need to be
installed on the host. Compose would then mount the host DIR
to the compute containers. A more efficient approach is to simply
install the nwfilter config/daemon in the libvirt container. Both
appoaches address the following error when booting an instance:
'no-mac-spoofing' is missing

Without pid: host, nova-compute and libvirt fail to operate correctly
together. I don't understand why, and I wish it weren't so, but it means
folks will have to install docker-compose from my personal github account
until the pull request is merged upstream.

This one uses the single environment file and has a few changes
to mounted directories.
