auksbicep/docker-led-service repository overview

⁠docker-led-service

Monitors number of docker containers running on Raspberry Pi, and will light up LED indicators for each container running.

⁠Details

LED Controller for Blinkt⁠. The service parses json out of the environmental variables, and uses compiled regular expressions in order to match image names of running Docker⁠ containers, and light up specified colors. Configuration loaded from Environment in alphabetical order, in the case of overlapping matches, first color match wins.

⁠Example

The following example will light up a red led for each running container with the words scheduler and arm in it's image tags. Blue for every running container with image tags matching apiserver, and purple for every running container with image tags with the word transaction.

docker run -d \
	-v /var/run/docker.sock:/var/run/docker.sock \
	--device /dev/gpiomem \
	-e DOCKER\_API\_VERSION=1.35 \
	-e DLS_IMAGE_COLOR_MATCH='{"match":"^(?=.*scheduler)(?=.*arm).*$", "r":255, "g":0, "b":0}' \
	-e DLS_IMAGE_COLOR_MATCH1='{"match":"apiserver", "r":255, "g":0, "b":255}' \
	-e DLS_IMAGE_COLOR_MATCH2='{"match":"transaction", "r":255, "g":0, "b":255}' \
