I2C inside a docker container
Trackback (most recent call last): file "test.py", line 124, in <module> bus = smbus.SMBus(1) IOError: [Errno 2] No such file or directory
If I run this on my raspberry pi and not in my container it works fine. But when I turn off my i2c pins on my raspberry pi it gives me the same error when running it. So I know it has to do with my i2c pins being activated. Does anyone know how to resolve this problem?

As a security precaution, system devices are not exposed by default inside Docker containers. You can expose specific devices to your container using the
--device option to
docker run, as in:
docker run --device /dev/i2c-0 --device /dev/i2c-1 myimage
You can remove all restrictions with the
docker run --privileged myimage
This will expose all of
/dev to your container, and remove other restrictions as well (e.g., you will be able to change the network configuration in the container and mount new filesystems).
