Hello Denis, and welcome. I think the best place to begin is probably with our Getting Started Guides, located here:

https://www.balena.io/docs/learn/getting-started/raspberrypi3/nodejs/

Once you are comfortable with Docker containers and builds, you can draw some inspiration from some of these guides, perhaps:

Thanks!

I develop with node red
1st question, is it really possible to integrate node red on the platform os balena 2.47?

I have a problem following the installation of the balena-node-red application

Blockquote
node-red node: error while loading shared libraries: libatomic.so.1: cannot open shared object file: No such file or directory

thanks

Hi @baudetd,

The balena-node-red project should be working, but I’ll give this a quick go on a device locally. Could you let me know what kind of device you’re using to try this?

Best regards,

Heds

with rpi 3b+ (not 64bits)

is the node red port still in 1880 ?

Hi @baudetd,

There does seem to be a problem with the project, and this is probably down to the fact that Node Red has been updated recently and now requires a new library. You can change this locally in your project by altering the node-red/Dockerfile file and changing:

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/*

to

RUN apt-get update && apt-get install -yq --no-install-recommends \
  rpi.gpio \
  python-dev \
  python-rpi.gpio \
  libatomic1 \
  && apt-get clean && rm -rf /var/lib/apt/lists/*

and then balena pushing the project again. This should then run as expected, and be available on port 80 of the device (http://<ipaddress>).

Best regards,

Heds

hello

it’s good !! thanks

however I have a few questions:

in node red, I tried to install node again but I have some s errors:

Blockquote
prebuild-install
2020-02-27T21:34:05.286Z [err] WARN install No prebuilt binaries found (target=12.16.1 runtime=node arch=arm libc= platform=linux)……

another question
in order to deply whole programs made under node red

is it possible to clone a project (node ​​red with flows) to other hardware

Hey, that warning that you posted shouldn’t be an issue, the build should go ahead and compile a version for you. I’m not entirely sure what you mean by the latter question though, could you please rephrase?
