cAdvisor on Synology

Running cAdvisor in Docker on Synology was a challenge, as it often wouldn’t start despite no changes to the launch options. The issue turned out to be related to the inotify settings.

The Problem

When running the following command to start cAdvisor:

docker run --name=cadvisor \
 --volume="/:/rootfs:ro" \
 --volume="/var/run:/var/run:ro" \
 --volume="/sys:/sys:ro" \
 --volume="/var/packages/ContainerManager/var/docker/:/var/lib/docker:ro" \
 --security-opt no-new-privileges=true \
 --restart=on-failure:5 \
 google/cadvisor:latest --docker_only=true

cadvisor:
 image: gcr.io/cadvisor/cadvisor:latest
 container_name: cadvisor
 read_only: true
 security_opt:
 - no-new-privileges=true
 command:
 - "--docker_only=true"
 volumes:
 - /:/rootfs:ro
 - /var/run:/var/run:ro
 - /sys:/sys:ro
 - /var/packages/ContainerManager/var/docker/:/var/lib/docker:ro
 restart: on-failure:5

I encountered the error:
