How to install perl Kafka::Connection on alpine image - perl

Question

I have a working UBUNTU image with this Dockerfile:
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"]
I'n trying to get a slimmer alpine version like this:
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
## some flags from http://git.alpinelinux.org/cgit/aports/tree/main/perl/APKBUILD?id=19b23f225d6e4f25330e13144c7bf6c01e624656

I keep getting this error
OS.c:18:10: fatal error: obstack.h: No such file or directory
#include <obstack.h> /* glibc's handy obstacks */
how do I get all the dependencies for Kafka on the image?

Answer 1

Alpine does not ship glibc, and obstack.h is not part of musl-dev.
Try alpine-pkg-glibc.

Answer 2

You could try grabbing obstack.h on Alpine by installing the newly available musl-obstack-dev package of the edge/testing repository:
apk add musl-obstack-dev --repository=http://dl-cdn.alpinelinux.org/alpine/edge/testing
Note that edge/testing packages are cutting edge and are considered experimental (as opposed to main stable package).
While Alpine (musl libc) is generally not glibc compatible, it does provide lightweight glibc compatibility in terms of convenience headers and libraries, particularly via the libc6-compat package, and packages as the aforementioned.
Tip: use Alpine's excellent package search for locating missing files. Alpine is vivid and active and sees new packages regularly. Most of the time you'll find that missing files are available in apk packages. Results for obstack.h package contents search:
https://pkgs.alpinelinux.org/contents?file=obstack.h&path=&name=&branch=edge

Answer 3

I eventually searched Github to find a newer alpine perl image and was greatly helped by valino's answer in arriving at this Dockerfile:
