There's some discussion in #8. If rustup works on Alpine now, someone could document this and specify how to run CI on Alpine.

#8 has been closed now and installing orjson==2.5.1 on Alpine Linux 3.11 and Rust 1.39.0 still does not work out of the box. Maybe with things like #8 (comment) . I would vote for re-opening and maybe pinning this ticket.

Using https://pkgs.alpinelinux.org/package/v3.11/community/x86_64/rust? That's stable, and this requires nightly. If you can document how to install it, great.

Yes and yes.

If you can document how to install it, great.

I stopped research half way due to timeout, so I cannot, at least yet.

So we cannot re-open and/or pin this ticket for the next person to maybe find this quicker?

Based on #8 (comment) by @scuml I can confirm that this Dockerfile works for orjson on Alpine 3.11:

FROM python:3.8-alpine

RUN apk update \
        && \
    apk add build-base wget

RUN wget -Oinit.sh https://sh.rustup.rs \
        && \
    sh init.sh -y \
        && \
    rm init.sh

ENV PATH="/root/.cargo/bin:${PATH}"

RUN rustup install nightly \
        && \
    rustup default nightly

ENV RUSTFLAGS="-C target-feature=-crt-static"

RUN pip install --no-binary=orjson orjson==2.5.1

RUN python -c 'import orjson; print(orjson.loads("[1, true]"))'

It took about 10 minutes total runtime over here.

The recipe above only works now with nightly-2020-09-14
Tested on python:3.8-alpine3.12 and orjson==3.3.1

FROM python:3.8-alpine3.12
RUN apk add build-base wget
ENV PATH="/root/.cargo/bin:${PATH}"
ENV RUSTFLAGS="-C target-feature=-crt-static"
RUN wget https://sh.rustup.rs -O rustup-init \
    && sh rustup-init -y --default-toolchain nightly-2020-09-14
RUN pip install --no-binary=orjson $(grep -o 'orjson[^#]*' runtime.deps)
RUN python -c 'import orjson; print(orjson.loads("[1, true]"))'

I am now testing on plain Alpine3.12, where binary manylinux build seems a bit slower...
