Raspberry pi zero support?

[dstewen]

I downloaded this about a week or 10 days ago. It was working with errors on my pi zero w.

Now getting the following errors when I try to restart the speedtest container via the Balena interface:

Note. I found I had to change the speedtest Dockerfile to the following to be able to download an image that includes python

FROM balenalib/raspberry-pi-alpine-python:3.7.7-build

WORKDIR /app

RUN pip3 install requests influxdb 

RUN wget https://bintray.com/ookla/download/download_file?file_path=ookla-speedtest-1.0.0-arm-linux.tgz -O speedtest.tgz

RUN tar -xvf speedtest.tgz

COPY . /app

ENTRYPOINT [ "python", "-u", "speedtest.py" ]

So my first question would be if the above python is the correct one I should be using.

Second question I have is I have noticed big gaps in the Grafana display of the data. I've got FREQUENCY set to 1800 (30 minutes) with the SERVER_ID variable set to the 1 server I want to test against and if I restart the container I will normally get 1 or 2 runs of the speedtest data collection script before it stops collecting for me and I have to restart it again.

@dstewen I've not tried this on a Pi Zero - there's a chance that the device does not have enough memory for the stack being used here. Can you check memory usage? My guess is that the OOM killer is killing the speedtest exe.

[n1md4]

I am trying to install this in an RPI0 and the 'speedtest' never starts, it continues attempting to download, and has never gotten past more than 17%.

[n1md4]

It doesn't appear memory is an issue:

I got some errors from the logs:

I'm guessing for my problem it is a lack of device space:

It was not due to the 2G SD card. I added an 8G and the same problem exists. The only [filtered] debugging I can see is this:

At which point, as noted above, the download starts over again.

[n1md4]

Made some progress, though a number of variables changed at the same time sooo ... here are my observations / actions:

1. github.com seemed to be up and down all day; either that or I have a dodgy connection, but everything else was working.
2. cloned internetspeedtest repo, before pushing to an application -- not sure what difference that makes, if any.
3. all containers now download images correctly, and from the cloud dash appear to be running, but ....

All services are in a constant state of restarting, no idea why:

Any ideas?

[n1md4]

Attempts to run 'device diagnostics' produces an error ssh client socket error while initiating SSH connection.

[n1md4]

I get this from journalctl:

That log shows output for influxdb, but it happens for all services.

[n1md4]

From diagnostics Supervisor is running, but may be unhealthy hmmm :thinking:

[phil-d-wilson]

Hey @n1md4 - that doesn't sound like a healthy device, rather than it being specific to running this repo. I'd pop along to the balena forums and get some support on the device itself.

I have been meaning to try and run this up on a PiZero, but haven't got round to it yet.

[tmigone]

Just to clarify here. The Dockerfiles on this project are all pinned to raspberrypi3 or arm32v6, neither will run on a Pi Zero. So as it stands Pi Zero devices are not supported.

[jellyfish-bot]

[tmigone] This issue has attached support thread https://jel.ly.fish/4ae32e2a-f6b3-4d54-a0d2-056335fe83b4

[phil-d-wilson]

With the release of the PiZero2, I don't personally have the time or energy to add support for the PiZeroV1. PRs welcome, but I won't be working on this myself.
