Hello all, I described use case and simple tool that I'd like to implement as a first step in this topic - would you please review it and provide me with feedback before I start coding? Is the use-case realistic? Is this tool going to be useful given the features I described? Any other comments? https://etherpad.openstack.org/p/kolla_upgrading_containers Thank you, -marek zawadzki -- Marek Zawadzki Mirantis Kolla Team
