Don't manage your application environment directly. Use deployment tool like Rancher / Kubernetes. Using one you will be able to upgrade your dockerized application without any downtime and even downgrade it should you need to.

Running Rancher is as easy as running another docker container as this tool is available in the Docker Hub.
