Hi Satish,

We used Docker-CE because RedHat based distros don't have Docker packages. It's fine to use docker.io for Ubuntu instead of docker-ce. It should work much more stable.

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?
