DockerThinPoolFillingUpFE

This alert is triggered when the available space on the node has been less than 20% of the minimal space required by the docker thin pool for at least 30 minutes.

If storage space is not recovered, Docker will soon not be able to pull new docker images and this can lead to a pod not being scheduled on the node.

Please see DockerThinPoolFilledUpFE for troubleshooting hints or solutions.
