I’m trying to upload a Node-RED application to my RaspberryPi4 running BalenaOs but i keep getting the same errors which all are about the RUN command in my dockerfile.
Specifically, the application i am trying to upload is this one and my dockerfile looks like this:
# Build step
###
FROM balenalib/%%BALENA_MACHINE_NAME%%-debian-node:12-stretch-build as build
RUN JOBS=MAX npm install -g --production --unsafe-perm \
node-red \
node-red-admin \
node-red-contrib-balena
###
# Runtime image
###
FROM balenalib/%%BALENA_MACHINE_NAME%%-debian-node:12-stretch-run
RUN apt-get update && apt-get install -yq --no-install-recommends \
rpi.gpio \
python-dev \
python-rpi.gpio \
&& apt-get clean && rm -rf /var/lib/apt/lists/*
# Defines our working directory in container
WORKDIR /usr/src/app
# Copy over the files created in the previous step, including lib/, bin/
COPY --from=build /usr/local/bin /usr/local/bin
COPY --from=build /usr/local/lib/node_modules /usr/local/lib/node_modules
# This will copy all files in our root to the working directory in the container
COPY ./app ./
# server.js will run when container starts up on the device
CMD ["bash", "/usr/src/app/start.sh"]
In case i remove the whole RUN section from the dockerfile then the code is being successfully uploaded to my raspberry and via the public url on the balena cloud i can access the Node-red editor and build my flows, though i’m missing the Raspberry_PI nodes and thus, i can’t use the raspberry GPIO’s in my flows.
Since i am fairly new to the whole balena/container scheme, it would be really appreciated if someone could support me with these errors. What is it i am missing here?
So I think this is probably down the use of the Raspberry Pi 4, which is a different architecture to that of the Pi3. You’ve got a couple of options here. The first is that you could run the armv7 (32bit) project on your Pi4 instead, which will allow you to use the same project with a couple of small changes to the Dockerfiles, replacing %%BALENA_MACHINE_NAME%% to raspberry-pi3. This will force the base images used to be for a Pi3.
The other alternative if you want to build them as 64bit, is to switch from using stretch to buster, as this release does include the relevant GPIO packages. In this case you’d want to change any occurrence of stretch to buster in the Dockerfiles. Note that we haven’t tried this ourselves and whilst it should work, you may see issues we have not encountered.
Thank you for your prompt reply.
Even though my goal is to build a 64bit image i tried both of your solutions. Running the armv7 was successful and everything worked as expected, but in the second case in which i switched every strech in my dockerfile to buster the build failed and didn’t released.
Here’s a look at the errors since i can’t include all the logs :

It looks like you’ve changed the initial base image type from build to run:
[main] Step 1/9 : FROM balenalib/raspberrypi4-64-debian-node:12-buster-run
This needs to be FROM balenalib/%%BALENA_MACHINE_NAME%%-debian-node:12-buster-build as build as it needs the build type to include all the tools to build the nodegyp modules. Additionally the as build is required to reference it in the next FROM command.
The only differences should be the stretch to buster changes as shown in the diff output below:
Thank you for your help, indeed changing the stretch to buster was enough for the project to be build.
I have just another question to ask you, i added another service to the project with a simple python script for spi transactions and now the image is not being build again because The command '/bin/sh -c pip install -r requirements.txt' returned a non-zero code: 1 . Could you please also assist me with this one?
More specifically the error that i am getting is this one:
The dockerfile for the new service looks like this.
FROM balenalib/raspberrypi3-python:3-buster-run
# Set our working directory
WORKDIR /usr/src/app
# Copy requirements.txt first for better cache on later pushes
COPY requirements.txt requirements.txt
# pip install python deps from requirements.txt on the resin.io build server
RUN pip install -r requirements.txt
# This will copy all files in our root to the working directory in the container
COPY . ./
# Enable udevd so that plugged dynamic hardware devices show up in our container.
ENV UDEV=1
# main.py will run when container starts up on the device
CMD ["python","-u","src/spi_balenaTest.py"]
In the requirements.txt the only thing is written is spidev and i included the new service in the docker-compose.yml file.
This is because the FROM balenalib/raspberrypi3-python:3-buster-run in your first line should again be FROM balenalib/raspberrypi3-python:3-buster-build. gcc is the GNU C Compiler which is a build tool, and not present in run base images.
There’s some general info about naming schemes and what is included in base images here and that should give you enough information to help you choose appropriate images in the future.
