Folks,

Playing with kolla and i decided to use docker.io installation (ubuntu
20.04) on controller nodes but when i run bootstrap-server it removed
docker.io and installed docker-ce version.

Question:
What is the best docker version to run in production for operator point of
view and better support and stability. docker.io maintained by debian
community and native support with Ubuntu distro. docker-ce is maintained by
the docker community which has better features etc but rapid growth but
does that matter for kolla?

Just curious, what if I add compute nodes in an existing cluster after many
months? In that case the docker-ce version will be changed. How to maintain
or pin docker-ce version?
