Alpine Linux - Error: Error loading shared library libsasl2.so.2

Environment Information

• OS: Alpine Linux 3.8
• Node Version: 10.13.0
• NPM Version: 6.0.0
• node-rdkafka version: 2.4.2

Hi, I am having an impossible time trying to get node-rdkafka to run inside an Alpine linux docker image. I am using node:10-alpine as my base and have installed all the desired packages defined: https://github.com/Blizzard/node-rdkafka/blob/master/examples/docker-alpine.md

when I “step into” the docker image and search for find / -name libsasl2* I get the following:

/usr/src/app # find / -name libsasl2*
/usr/lib/pkgconfig/libsasl2.pc
/usr/lib/libsasl2.so.3
/usr/lib/libsasl2.so
/usr/lib/libsasl2.so.3.0.0
/usr/src/app/node_modules/node-rdkafka/deps/librdkafka/packaging/cmake/try_compile/libsasl2_test.c

so libsasl2.so.3 is available but libsasl2.so.2 is nowhere to be found.

If I switch to a node:10.13.0-stretch docker base image and install libsasl2-dev

# find / -name libsasl2.*
/usr/lib/x86_64-linux-gnu/libsasl2.a
/usr/lib/x86_64-linux-gnu/pkgconfig/libsasl2.pc
/usr/lib/x86_64-linux-gnu/libsasl2.so
/usr/lib/x86_64-linux-gnu/libsasl2.so.2
/usr/lib/x86_64-linux-gnu/libsasl2.so.2.0.25

So it appears Alpine no longer has the desired version of libsasl2 required for librdkafka ?

does anyone have a work around for this? Is there an older package I can install somehow?

Thanks!

I used node:10-alpine and it worked. Dockerfile:

FROM node:10-alpine

RUN apk --no-cache add \
      bash \
      g++ \
      ca-certificates \
      lz4-dev \
      musl-dev \
      cyrus-sasl-dev \
      openssl-dev \
      make \
      python

RUN apk add --no-cache --virtual .build-deps gcc zlib-dev libc-dev bsd-compat-headers py-setuptools bash

# Create app directory
RUN mkdir -p /usr/src/app
WORKDIR /usr/src/app

# Install app dependencies (allow caching)
COPY package.json yarn.lock /usr/src/app/
RUN yarn install --pure-lockfile

COPY . /usr/src/app/

EXPOSE 3000

CMD [ "yarn", "start" ]

Did you add a .dockerignore file to your repo? It may be happening because you are overriding the lib that is built inside the container with your local node_modules 🤔

hi @Chebura I resolved it by making sibling. I am using centos8. here is my docker file inputs:

RUN yum -y install epel-release python3-configobj gcc python3-devel
RUN yum -y install openssl-devel
RUN cd /usr/lib64 \
 && ln -s  /usr/lib64/libsasl2.so.3.0.0 libsasl2.so.2
RUN yum install cyrus-sasl-md5 cyrus-sasl-plain cyrus-sasl-gssapi cyrus-sasl-devel -y
RUN yum install -y gcc-c++
RUN dnf install -y librdkafka

hope it helps
