Monitorix is a free, open source, lightweight system monitoring tool designed to monitor as many services and system resources as possible.
This container enables you to start a monitoring webinterface on your Raspberry Pi in seconds without any configuration.
docker pull jpdus/rpi-monitorix
docker run --name monitorix --net host -e MONITORIX_PORT=8080 -d jpdus/rpi-monitorix
Afterwards just visit http://yourip:8080/monitorix for statistics.
Instead of --net host you can also map a port:
docker run --name monitorix -p 8080:8080 -d jpdus/rpi-monitorix
