Docker Ubuntu 18.04 image with Python 3.7

Dockerfile

FROM ubuntu:18.04

# There is no official Ubuntu-18-based image for Python in Вocker Hub.
# But using Ubuntu 18 as a base (for everything that can't run in Alpine) is a requirement from SEC team.
# So we compile Python into Ubuntu-18 image ourselves

ENV PYTHON_VERSION 3.7.7
ENV PYTHON_PIP_VERSION 20.1
ENV DEBIAN_FRONTEND=noninteractive

# Ensure that the local python is preferred over distribution python
ENV PATH /usr/local/bin:$PATH

# http://bugs.python.org/issue19846
# > At the moment, setting "LANG=C" on a Linux system *fundamentally breaks Python 3*, and that's not OK.
ENV LANG C.UTF-8
