[Yann E. MORIN]

Ricardo, All,

On 2018-03-13 00:09 -0300, Ricardo Martincoski spake thusly:
> Use the latest version of the tool because it is actively maintained.
> But use a fixed version of the tool and its dependencies to get stable
> results. It can be manually bumped from time to time.
> 
> Before installing any Python packages, ensure pip, setuptools, and wheel
> are up to date as recommended in the docs [1].

> Changes v2 -> v3:  (suggested by Yann E. MORIN)
>   - minimise the number of intermediate layers;
>   - explain why install setuptools separately using the latest version
>     (I actually just used the exact command line from the docs and
>     referenced it in the commit log);
>   - use a single package on each line, sorted.
> 
> Changes v1 -> v2:  (suggested by Yann E. MORIN)
>   - install flake8 to the base docker image instead of adding sudo to
>     install tools on the fly.
