Lab 8.1 error deploying cAdvisor with Docker
I get the following error when I try to deploy cAdvisor using Docker for lab 8.1. Any advice?
$ docker run \

> --volume=/var/run:/var/run:ro \
> --volume=/sys:/sys:ro \
> --volume=/var/lib/docker/:/var/lib/docker:ro \

> --publish=8080:8080 \
> --detach=true \
> --name=cadvisor \
> gcr.io/google-containers/cadvisor:v0.36.0

I have a similar problem
docker: Error response from daemon: error while creating mount source path '/host_mnt/private/var/lib/docker': mkdir /host_mnt/private/var/lib/docker: operation not permitted.
Any help on that ?0 -

Hello,
I'm also at that point. I try to start the docker imager for cadvisor, but it fails, due to missing /var/lib/docker
[root@mlaeufer-prometheus apps]# docker run --volume=/:/rootfs:ro --volume=/var/run:/var/run:ro --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

ls: cannot access '/var/lib/docker/': No such file or directoryThe underlying host OS: Fedora Linux 38 (Cloud Edition)
What happens if we don't attach /var/lib/docker to the container?
Thanks an best regards

I got it halfway running (started as root):
# docker run --volume=/:/rootfs:ro --volume=/var/run:/var/run:rw --publish=8080:8080 --detach=true --name=cadvisor --privileged=true gcr.io/cadvisor/cadvisor:latest
But:
the part with /var/lib/docker is removed
the version is latest
Status is unhealthy:# docker container ls -a Emulate Docker CLI using podman. Create /etc/containers/nodocker to quiet msg. CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 788645b2945c docker.io/grafana/grafana:7.5.4 4 days ago Up 4 hours 0.0.0.0:3000->3000/tcp grafana d3e2783601c3 gcr.io/cadvisor/cadvisor:latest 11 minutes ago Up 11 minutes (healthy) 0.0.0.0:8080->8080/tcp cadvisor
But it's reachable on port 8080. Let's see how far I go on with the Lab.

Unfortunately I can't get the cadvisor running fully.
Indeed the cadvisor container gets started, but the metrics exposed don't have the id= label, only the id=/ I can see. Also the metric container_cpu_usage_seconds_total is not existing at all.
Furthermore , when I search for container_memory_usage_bytes I only get forcontainer_memory_usage_bytes{id="/", instance="localhost:8080", job="cadvisor"}
So I can't continue with this chapter. I need a docker training before.
