[英]Failed to install pyorc on alpine docker container
出现编译错误 - 这取决于 ORC 二进制文件。
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
如果我也单独编译apache-orc ,我该如何参考 PyOrc Pip 安装?
任何人都有任何解决方案或想法,我们如何在高山容器内安装pyorc package。
我在使用 ubuntu 和正常 python docker 图像的高山图像时遇到问题,它运行良好。
Docker 图片: FROM python:3.7-alpine
我使用了 Docker 多阶段构建:
# 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 .
它似乎工作:
$ docker build -t test .
$ docker run -it --rm test python
Python 3.7.3 (default, Jun 27 2019, 22:53:21)
[GCC 8.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import pyorc
>>>
>>> with open("./new_data.orc", "wb") as data:
... with pyorc.Writer(data, "struct<col0:int,col1:string>") as writer:
... writer.write((1, "ORC from Python"))
...
>>> from pathlib import Path
>>> Path("./new_data.orc").read_bytes()
b'ORC\x1d\x00\x00\n\x0c\n\x04\x00\x00\x.....'
作者Noirello给了我如下指南/方向:
对于 Alpine,必须从源代码安装它。 文档中有一些说明如何操作: pyOrc-Docs
我会使用多阶段 Dockerfile 来构建 pyorc,然后使用应用程序的 rest 将轮子安装到干净的 Alpine 映像中。
