Hey there, trying to play around with mediaoup in alpine linux (run in a docker container) to figure out the right docker deployment but here’s a problem on installation:
This will happen if you’re running in a container environment or environment that otherwise doesn’t have kernel headers.
1 minute search says that if you install linux-headers package the error should go away.
Issue solved.
Thanks for the help and the quick respone.
Some people (including myself) have had some very difficult to debug networking issues with mediasoup on alpine-linux. I think it has something to do with UDP support in libuv on alpine. I’m not sure if the bug is with libuv or alpine, but switching to the standard ubuntu-based docker image for node fixes it.
It’s possible this doesn’t happen anymore, but wanted to give you a heads up just in case. There’s more information in these threads:
I’m build docker image on Mac using ubuntu-20.04 base image, trying use a alternative linux-header version, but still get the error:

I just tried build docker image on native Ubuntu-20.04 host, not Mac, but still get the same error, My Dockerfile:

Does the error relate to node-v14.17.6-linux-x64.tar.xz which i download from nodejs site?
RUN apt-get update && apt-get install -y nodejs npm
After i switch the nodejs version to apt installed package, everything works fine.
Hi,
We are also trying to create a docker image for our Project that uses Mediasoup,
Sharing the File
`FROM node:14.17.3-alpine
MAINTAINER Gary Ascuy gary.ascuy@gmail.com
ENV BUILD_PACKAGES=“python make gcc g++ git libuv bash curl tar bzip2”
NODE_ENV=production
ROOT_URL=http://localhost:3000 \
PORT=3000
WORKDIR /root/app/bundle
ADD bitovn-bridge-meteor.tar.gz /root/app
RUN apk add --update linux-headers-$(uname -r)
RUN apk --update add ${BUILD_PACKAGES}

&& apk --update del ${BUILD_PACKAGES}
EXPOSE 3000
CMD node --expose-gc --max-old-space-size=4096 main.js
`
& getting the same error, & if we trying to add
RUN apk add --update linux-headers-$(uname -r)
then this issues comes
Can you please check what is the issue?
The error says that you’re trying to install a package that doesn’t exit. Is there a reason you’re adding $(uname -r) to the package name?
Have you tried installing just “linux-headers”. That’s what I did when I was using alpine.
BTW, I switched to ubuntu because of issues with UDP (as explained earlier in this thread). I’m not sure if this has been fixed, but be aware of it.
It works
