Docker [Alpine]: uWebSockets is incompatible

[dalisoft]

Hi, @alexhultman

I trying within Docker with this node alpine, but says this library is incompatible.

Reason: Alpine uses musl instead, source here and here

Related issue: #140

I will track this issue here and will add solution on README

Binaries are not compatible with Alpine since it is using a different libc. You can compile your own binaries if you insist on using this particular embedded dist.

Sorry @alexhultman, you here wrong, binaries supports Alpine and even CentOS, see my answer below and if you think my answer helpful, you can mark as Answer.

If anyone also gets this issue, you can try

RUN ln -s /lib/libc.musl-x86_64.so.1 /lib/ld-linux-x86-64.so.2 command.
It worked for me.
uWebSockets.js is amazing, even binaries works with this command.

If you need solutions for Docker/Linux issues, look at here as my library works on top of uWebSockets.js

same solution but for multiple architectures
RUN ln -s "/lib/libc.musl-$(uname -m).so.1" "/lib/ld-linux-$(uname -m).so.1"

I can run uwebsocket.js inside Docker with additional: RUN apk add --no-cache gcompat

Bro, you saved my 3 days. I want to write a poetry for this answer.

Sometimes I feel that my brain is going to blow.

Thanks to all github bros who opens window.

Had to adjust the fix slightly to work on different architectures.

Adding this to my Dockerfile allowed uws to work:
RUN ln -s "/lib/libc.musl-$(uname -m).so.1" "/lib/ld-linux-$(uname -m).so.1"
