Docker node:8.5.0-alpine

Hi…

I have 2 Dockerfiles very similar in my project (you can see below) Using node:8.5.0 works fine

But using node:8.5.0-alpine I’ve got this error: Segmentation fault

I tried this: npm i --silent --build-from-source --progress=false --production in alpine… unsuccessfully 😞

I discovered that:

Alpine uses musl instead of glibc, and therefore binaries built with gcc for glibc will be binary incompatible, as far as I’m aware.

Is there anyway for the levelup to work on the node:alpine?

Tks!

@ralphtheninja you are right. for building from source we need additional packages:

FROM node:8.4-alpine
RUN apk add --update python make g++ && \
    npm install -g standard tape faucet levelup@1.3.9
WORKDIR /usr/local/lib/node_modules/levelup
RUN npm install --build-from-source && \
    standard && \
    tape test/*-test.js | faucet

And the result:

# tests 137
# pass  137
✓ ok

Thanks!
