Base Docker image for ubuntu-16.04 & Python3.6

Ubuntu1604py36Dockerfile

# docker build -t ubuntu1604py36
FROM ubuntu:16.04

RUN apt-get update && \
  apt-get install -y software-properties-common && \
  add-apt-repository ppa:jonathonf/python-3.6
RUN apt-get update

RUN apt-get install -y build-essential python3.6 python3.6-dev python3-pip python3.6-venv
RUN apt-get install -y git

# update pip
RUN python3.6 -m pip install pip --upgrade
RUN python3.6 -m pip install wheel

Slightly modified and better working Dockerfile would be as follow:

# docker build -t ubuntu1604py36
FROM ubuntu:16.04

RUN apt-get update && \
        apt-get install -y software-properties-common vim
        add-apt-repository ppa:jonathonf/python-3.6
RUN apt-get update -y

RUN apt-get install -y build-essential python3.6 python3.6-dev python3-pip python3.6-venv && \
        apt-get install -y git

# update pip
RUN python3.6 -m pip install pip --upgrade && \
        python3.6 -m pip install wheel

RUN apt-get update &&
apt-get install -y software-properties-common vim
add-apt-repository ppa:jonathonf/python-3.6

Should be

RUN apt-get update && \
  apt-get install -y software-properties-common vim && \
  add-apt-repository ppa:jonathonf/python-3.6

I don't think it is a good choice with too many RUN commands, because it will create too many file layers. Plz check with the following code:

FROM ubuntu:16.04

RUN apt-get update && \
        apt-get install -y software-properties-common && \
        add-apt-repository ppa:jonathonf/python-3.6 && \
        apt-get update -y  && \
        apt-get install -y build-essential python3.6 python3.6-dev python3-pip && \
        apt-get install -y git  && \
        # update pip
        python3.6 -m pip install pip --upgrade && \
        python3.6 -m pip install wheel

Its no good now.
ppa:jonathonf was removed by the developer.

I just found out the same thing.
Updated my script to ppa:deadsnakes/ppa.

Cannot add PPA: 'ppa:~deadsnakes/ubuntu/ppa'.
ERROR: '~deadsnakes' user or team does not exist.
The command '/bin/sh -c add-apt-repository ppa:deadsnakes/ppa' returned a non-zero code: 1

What other PPA can I use here? Any help on this is appreciated.
Thanks in Advance

@arunkumarchan

add-apt-repository ppa:deadsnakes/ppa

Env variable in not set in this ..

Now is December 2020, your code doesn't work.

Somehow, those codes just got us Python 3.5.2, not Python 3.6.

so how can we get python 3.6

I have to build Images FROM ubuntu:18.04.

This way works.

In case you must use 16.04 only, I have no idea.
