Base for a tiny docker image containing pigpio. Aims to support all models of raspberry pi.

docker-alpine-pigpiod's Issues

RPi4 64-bit

Hi,
thank you for your work, in concept it should be all I need.

To put you on context, I'm using a 64-bit OS (Ubuntu Server 20) on my Raspberry Pi 4, 4Gb and need to control the GPIO remotely. Preferably, using a docker container would be ideal. I have tried a couple of things that I would like to share:

1. Directly using this instructions on the host OS made it possible to remotely control de GPIO. This tells us that is not a host OS related issue.

2. Adapting you Dockerfile to use ubuntu as it's base image

# Based on Alpine, a tiny linux distribution
FROM ubuntu as builder
# Install basic package to compile source code
#RUN apk add alpine-sdk
RUN  apt-get update \
  && apt-get install -y wget unzip build-essential
# Follow the install guide from creator of pigpio, http://abyz.me.uk/rpi/pigpio/download.html
RUN wget --output-document=download.zip https://github.com/joan2937/pigpio/archive/master.zip \
# Downloaded content is placed inside specific folder to not be depended of branch naming from repo
    && mkdir download \
    && unzip -d download download.zip \
    && cd /download/* \
# Fix for compiling on Alpine, https://github.com/joan2937/pigpio/issues/107
    #&& sed -i -e 's/ldconfig/echo ldconfig disabled/g' Makefile \
    && make \
    && make install
# Start of new base image
FROM ubuntu
LABEL maintainer="[email protected]"
COPY --from=builder /usr/local /usr/local
# Copy app into image
COPY start.sh /start.sh
# Make sure file has execution permission
RUN chmod +x /start.sh
# Start app
CMD /start.sh

gave the following error (using or not the --privileged flag)

Checking who is listening/bound to port 8888 ...
/start.sh: 4: netstat: not found
...OK, no process is listing/bound to port 8888
Starting daemon pigpiod ...
pigpiod: error while loading shared libraries: libpigpio.so.1: cannot open shared object file: No such file or directory
... daemon stopped unexpectedly.
netstat -tlep | grep 8888
/start.sh: 24: netstat: not found
sleeping for 20 sec - we hope that this releases the bound TCP port 8888
end of sleep
netstat -tlep | grep 8888
/start.sh: 29: netstat: not found
... start.sh terminated

What should we try next?
