Failed to get containers "/" in cAdvisor Docker - linux

Question

I runned cadvisor docker with this command
docker run \
--volume=/:/rootfs:ro \
--volume=/var/run:/var/run:rw \
--volume=/sys:/sys:ro \
--volume=/var/lib/docker/:/var/lib/docker:ro \
--volume=/dev/disk/:/dev/disk:ro \
--publish=8080:8080 --detach=true \
--name=cadvisor \
gcr.io/google-containers/cadvisor:v0.36.0
I can run without getting error:
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
a0aa3cc8d5f2 gcr.io/google-containers/cadvisor:v0.36.0 "/usr/bin/cadvisor -…" 48 seconds ago Up 48 seconds (healthy) 0.0.0.0:8080->8080/tcp, :::8080->8080/tcp cadvisor
When I go to localhost:8080, I give me this error messages
failed to get container "/" with error: unable to find data in memory cache
I tried with sudo docker run still same error.
How can I fix this? Is this docker related or cadvisor?

Answer 1

I had this issue because old cadvisor version don't support "recent" cgroups version.
I upgraded to fix the issue.
Troubleshooting tips
Use docker logs to retrieve cadvisor logs. Mine showed errors like:
W0107 09:20:00.064502 1 container.go:526] Failed to update stats for container "/system.slice/cups.service": \
