From what I understood, it is possible to build an arm64v8 image on the Docker Hub infrastructure (that use amd64). According to this thread it can be done using Qemu.
So I added a pre_build hook:
#!/bin/bash
docker run --rm --privileged multiarch/qemu-user-static:register --reset
The Qemu binaries are also downloaded inside the container:
FROM alpine AS builder
RUN apk update
RUN apk add curl
WORKDIR /qemu
# downloaded here...
RUN curl -L https://github.com/balena-io/qemu/releases/download/v3.0.0%2Bresin/qemu-3.0.0+resin-arm.tar.gz | tar zxvf - -C . && mv qemu-3.0.0+resin-arm/qemu-arm-static .
FROM area51/gdal:arm64v8-2.2.3
# ...then added here
COPY --from=builder /qemu/qemu-arm-static /usr/bin
RUN apt-get update
RUN apt-get install -y libgdal-dev python3-pip libspatialindex-dev unar bc
ENV CPLUS_INCLUDE_PATH=/usr/include/gdal
ENV C_INCLUDE_PATH=/usr/include/gdal
ADD ./requirements.txt .
RUN pip3 install -r requirements.txt
RUN mkdir /code
ADD . /code/
WORKDIR /code
CMD python3.5 server.py
EXPOSE 8080
Unfortunatly, it doesn’t works:
Cloning into '.'...

Switched to a new branch 'auto-build'

The command '/bin/sh -c apt-get update' returned a non-zero code: 1
The error:
standard_init_linux.go:190: exec user process caused "no such file or directory"
Looks like that one:
standard_init_linux.go:190: exec user process caused "exec format error"
That I’m starting to be used to see and means that there is an architecture problem. Does the first one mean the same thing?
If there is again an architecture problem, what I’m missing?
