PhidgetSBC with docker

[ouzarf]

Hello,
I'm trying to use Docker to control my phidgets on the PhidgetSBC, after installing the phidget drivers and python library on the docker container and trying to read from a voltage Input, I'm getting this message:
"No Phidgets were detected at all. Make sure your device is attached."
When I run the python script without docker it works fine, I am attaching the /dev folder to the container and using the --privileged mode to access devices on the host but it didn't change much, what do you think I am missing?

Thanks!

Update:

I ran it on debug mode and this the log:


****************************** Logging Enabled ******************************

Increasing the timeout to 30000 didn't change anything,
wdyt?

You will have to attach the Phidget USB device to the docker container somehow, if that is possible, or alternatively you could run the Phidget network server and connect to the Phidget via the network.

If you move to a networked scenario:

Over the network, "device discovery" is based on mDNS which is the local subnet only.

If you need to access network devices outside your subnet (and they are reachable) you need to access them explicitly using IP addresses, you can't do a discovery

For example I was VPN'ing into my environment and I could ping my phidget by IP, but because my VPN server gave me an IP in a different range to the phidget, I could not discover it, however with its IP I could control it directly.
