Proxy traffic to web application Docker containers with nginx and Let’s Encrypt

I’ve been using Docker for a while now. The idea of running everything the same anywhere is like a dream come true and not having to worry about updating a package dependency on the server and breaking everything. For example the same server running multiple Python applications which require different versions. Ever since I moved from Digital Ocean to Scaleway I have begun to use Docker for almost everything I run on my Scaleway servers.
