如何在高山映像上安装 perl Kafka::Connection

Question

我有一个使用这个 Dockerfile 的 UBUNTU 映像：

FROM perl:5.14

ENV DEBIAN_FRONTEND noninteractive

RUN apt-get update -y
RUN apt-get upgrade -y
RUN apt-get install -y libgd-dev

RUN perl -MCPAN -e 'install (Try::Tiny)'
RUN perl -MCPAN -e 'install (Kafka::Connection)'
RUN perl -MCPAN -e 'install (YAML)'
RUN perl -MCPAN -e 'install (GD::Simple)'
RUN perl -MCPAN -e 'install (GD::Graph)'
RUN perl -MCPAN -e 'install (JSON)'
RUN perl -MCPAN -e 'install (JSON::MaybeXS)'
RUN perl -MCPAN -e 'install (HTTP::Request)'
RUN perl -MCPAN -e 'install (HTTP::Response)'
RUN perl -MCPAN -e 'install (HTTP::Daemon)'

COPY run.sh /run.sh

RUN chmod +x "/run.sh"

RUN mkdir -p /code_path

WORKDIR /code_path

CMD ["/run.sh"]

我正在尝试获得像这样更纤薄的高山版本：

FROM alpine:3.10.3

## alpine curl and wget aren't fully compatible, so we install them
## here. gnupg is needed for Module::Signature.
RUN apk update && apk upgrade
RUN apk add curl tar make gcc build-base wget gnupg

RUN mkdir -p /usr/src/perl

WORKDIR /usr/src/perl

## from perl; `true make test_harness` because 3 tests fail

RUN chmod +x "/run.sh"

RUN mkdir -p /code_path

我不断收到此错误

OS.c:18:10: fatal error: obstack.h: No such file or directory
 #include <obstack.h>    /* glibc's handy obstacks */

如何获取图像上 Kafka 的所有依赖项？

Answer 1

Alpine 不提供 glibc，obstack.h 不是 musl-dev 的一部分。

试试alpine-pkg-glibc。

Answer 2

您可以尝试通过安装edge/testing 存储库的新可用musl-obstack-dev 包来在Alpine 上获取obstack.h：

apk add musl-obstack-dev --repository=http://dl-cdn.alpinelinux.org/alpine/edge/testing

请注意，edge/testing 包是最先进的，被认为是实验性的（与主要稳定包相反）。

虽然 Alpine (musl libc) 通常不兼容 glibc，但它确实在方便的头文件和库方面提供了轻量级的 glibc 兼容性，特别是通过 libc6-compat 包和上述包。

提示：使用 Alpine 出色的包搜索功能来查找丢失的文件。 Alpine 活泼好动，经常看到新的包裹。大多数情况下，您会发现丢失的文件在 apk 包中可用。 obstack.h 包内容搜索结果：
https://pkgs.alpinelinux.org/contents?file=obstack.h&path=&name=&branch=edge

Answer 3

我最终在 Github 上搜索了一个 newer alpine perl image，并在得到这个 Dockerfile 时得到了 valino's answer 的极大帮助：

FROM alpine:3.10.3
