This is an interesting idea, but I feel like it is a big oversight not to have build in support for automatically getting certificates.
Instead the docs have you do something manual with certbot (a complete nono if you believe in automatic SSL and are using docker images that don't persist data, as Docker is meant to be used).
The only reason I have SSL on my domain in the first place is that my host offers a simple setup that runs automatically.
Which means now you can't do a clean deploy of a new version, you can't be sure that what works on one machine is the same as what works on another etc.
