Compile MDV as a binary using pyinstaller (in Docker)

[pascalandy]

This one is for the folks who love Docker and love to optimize their docker images.

1) Works but it's heavy

It's easy to run mdv in Docker. Size: 123MO (compressed)

Dockerfile

FROM python:3.8.1-alpine3.11 as binary
RUN pip install mdv
ENTRYPOINT [ "mdv" ]

docker image ls

devmtl/mdv                                                      edge_2020-02-01_19H25   049c6215fcc1        About an hour ago   123MB

2) Optimizing

I'd like to compile MDV as a binary using pyinstaller. This will make the final image much smaller using a multi-stage build.

This is what I got so far

Dockerfile

FROM python:2.7.17-alpine3.11 as core

RUN set -eux && apk update && apk add --no-cache \
  'su-exec>=0.2' git nano bash upx curl wget && \
  \
### gcc / c compiler required by cython
  apk update && apk add --no-cache \
  build-base && \
  \
### pyinstaller will make mdv compile as a binary
  pip install pyinstaller && \
  \
### dep for mdv
  pip install markdown && \
  pip install pygments && \
  pip install pyyaml && \
  pip install docopt && \
  pip install tabulate && \
  \
### install from source
  git clone https://github.com/axiros/terminal_markdown_viewer.git --depth 1 && \
  cd terminal_markdown_viewer                                       && \
  pyinstaller -F setup.py

Everything seems to compile as expected

cd dist && \
chmod +x setup

Let's run it:

/terminal_markdown_viewer/dist # echo; pwd; echo; ls -AlhF; echo; du -sh *; echo; du -sh;
/terminal_markdown_viewer/dist
total 10M
-rwxr-xr-x    1 root     root        9.5M Feb  2 01:58 setup*
9.5M	setup

/terminal_markdown_viewer/dist # setup
sh: setup: not found
/terminal_markdown_viewer/dist # ./setup
sh: ./setup: not found

Any ideas?
