Cannot really help you with your specific problem, just my 2 cents: I just started it via docker on my machine (xubuntu 19.10). I see those warnings, but it still works as expected.

Versions of docker & docker-compose (quite old version, I know) I used:

$ docker-compose version
docker-compose version 1.18.0, build 8dd22a9
docker-py version: 2.6.1
CPython version: 2.7.13
OpenSSL version: OpenSSL 1.0.1t  3 May 2016
