Docker compose - sys.stderr.write(f"ERROR: {exc}") : invalid syntax

[johhnry]

Hi,

Steps to reproduce

I did the following steps on a CentOS Linux 8 x86_64 :

$ git clone https://github.com/cgwire/cgwire
$ cd cgwire/compose
$ docker-compose up -d

Issue

and I have the following error at step 17/34 :

Step 17/34 : RUN python3 -m venv /opt/zou/env &&     /opt/zou/env/bin/pip install --upgrade pip setuptools wheel &&     /opt/zou/env/bin/pip install zou==${ZOU_VERSION} &&     rm -rf /root/.cache/pip/

Seems related to the fact that pip dropped support for python 2 and 3.5 (in this case) : https://stackoverflow.com/questions/66212924/pip-sys-stderr-writeferror-exc-with-python-3-5

I don't really know how to solve that : the ubuntu 16.04 base image install python3.5 with apt? It's also mentionned that python2 is needed for supervisord in the Dockerfile (I also saw the usage of tini so what's the link between the two?)

Thanks again for making this open source!
