standard_init_linux.go:207: exec user process caused "exec format error"

Describe the bug

When I run docker with this container on Raspberry PI I see the following error:

standard_init_linux.go:207: exec user process caused "exec format error"

I think it may be related to that Raspberry PI 3 is ARM based.

Environment (please complete the following information):

• OS: ubuntu-18.04.2-preinstalled-server-armhf+raspi3.img.xz

Used app version:

• Docker: bpatrik/pigallery2:1.5.6-stretch

I managed to build working image on aarch64 (Raspberry Pi 3 B+) from this Dockerfile:

FROM node:10-stretch-slim as builder

RUN apt-get update \
 && apt-get install -y python build-essential unzip \
 && rm -rf /var/lib/apt/lists/*

RUN wget https://github.com/bpatrik/pigallery2/releases/download/1.5.6/pigallery2.zip \
 && unzip pigallery2.zip -d pigallery2
RUN cd /pigallery2 \
 && npm install


FROM node:10-stretch-slim

RUN apt-get update \
 && apt-get install -y ffmpeg \
 && rm -rf /var/lib/apt/lists/*

COPY --from=builder /pigallery2 /app

WORKDIR /app

EXPOSE 80

CMD npm start

It should work for any architecture which is supported by node docker image.

Hi

Yes its the issue with the ARM based architecture. I tried to quickly create an arm32v7 based docker image (see here), but it was not that straightforward. It might take some time for me to figure out the solution. In the meantime you can try:

• Building the Docker file on your own on the raspberry
• Skipping the docker and running the app from source / release

Update: This might be it. As far as I understand [1, 2], there isn’t any straightforward way of building an arm based image on (a x86 based) docker hub. I’ll update the document to reflect this and leave the arm based container there if someone wants to build the image.
