A container image that uses a Piglow (https://shop.pimoroni.com/products/piglow) to display the CPU load of a Raspberry Pi.
The container should be run with
--device /dev/i2c-1 so that the container can access the I2C bus driver. The
/etc/modules file on the host must be modified by adding
i2c-bcm2708 (each on a separate line). The
/boot/config.txt on the host must also be adapted by adding a line with
Dockerfile and more explanations can be found at https://github.com/jmMeessen/rpi-docker-images/tree/master/rpi-piglow-cpu
