Failed to install pyorc on alpine docker container

Question

Getting compilation error - which is dependent on ORC binaries.

In file included from src/_pyorc/_pyorc.cpp:1:
src/_pyorc/Reader.h:7:10: fatal error: 'orc/OrcFile.hh' file not found
#include "orc/OrcFile.hh"
         ^~~~~~~~~~~~~~~~
1 error generated.
error: command 'clang' failed with exit status 1

If I compile apache-orc separately then too, how can I give reference of it to PyOrc Pip Installation?

Anyone has any solution or idea how can we install pyorc package inside alpine container.

I'm having trouble with alpine image with ubuntu and normal python docker image its working well.

Docker Image: FROM python:3.7-alpine

Answer 1

I used Docker multi-stage builds:

# Dockerfile

FROM python:3.7.3
WORKDIR /app
RUN pip install pyorc -t .

FROM python:3.7.3-alpine
WORKDIR /app
RUN apk add --no-cache --virtual .build-deps g++ musl-dev gcompat
COPY --from=0 /app .

and it seems working:

$ docker build -t test .
$ docker run -it --rm test python
