Suport Alpine, non glibc

galo commented 5 years ago

Summary

Can wasmer/wapm run on Alpine distributions without glibc, so it can be packaged in container such as

FROM alpine:3.8
RUN mkdir -p /home/app
RUN apk --no-cache add curl \
    libc6-compat \
    libstdc++ \
    curl https://get.wasmer.io -sSfL | sh 
RUN wapm install cowsay
CMD [ "wapm ", "run", "cowsay" ]

This is an interesting idea, thanks for suggesting it!

I messed around with this a bit yesterday and ran in to some surprising issues. Here's what I ended up with (working around curl not having -L and the env vars not being set correctly):

FROM alpine:3.9
RUN mkdir -p /home/app
RUN apk --no-cache add curl \
    libc6-compat \
    gcompat \
    libstdc++
RUN curl https://raw.githubusercontent.com/WAFoundation/wasmer/master/install.sh -sf | sh 
ENV WASMER_DIR="/root/.wasmer"
ENV WASMER_CACHE_DIR="/root/.wasmer/cache"
ENV PATH="$WASMER_DIR/bin:$WASMER_DIR/globals/wapm_packages/.bin:$PATH"
RUN wapm install cowsay
CMD [ "wapm ", "run", "cowsay" ]

I don't have the context right now on what we'd have to do to start, or the trade offs of, compiling without glibc in Rust, but it's something we can certainly look into!

To immediately answer your question: it can't right now.

@MarkMcCaskey @syrusakbary Any update on this? It would be really nice to be able to run wasmer in a minimal container.

An update on this would be nice.

With the compat libs suggested above, on alpine 3.11.3, I got:
