Compile MDV as a binary using pyinstaller (in Docker) #80

Open pascalandy opened 4 years ago

pascalandy commented 4 years ago

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?
