[telegraf-ds] MountVolume.SetUp failed for volume "docker-socket"

I tried installing this chart onto my local k3s cluster and ran into this issue:

  Warning  FailedMount  67s (x18 over 21m)   kubelet            MountVolume.SetUp failed for volume "docker-socket" : hostPath type check failed: /var/run/docker.sock is not a socket file

I don't see a docker.sock on the host. Docker is also not running on the host (I believe k3s just uses containerd?). Is it possible to make this configurable or is access to docker.sock required for the DaemonSet to function?

Alternate route is to just install Telegraf on the host directly I assume?

Can you try installing the chart with --set config.docker_endpoint="" ?

@alespour I got this working today on my amd64 NUC nodes. Getting ErrImagePull on my Pi 4B nodes, though I'm guessing that is not related.

@joestump I think alpine-based images are only for linux/amd64, if you could try just 1.21 or latest (or 1.22) for recently released 1.22, these are available for amd64, arm64v8 and arm32v7.

--set image.tag=1.21

@joestump please, could you share your (sanitized) values.yml? Mine is this

USER-SUPPLIED VALUES:
config.docker_endpoint: ""
config.outputs:
- influxdb_v2:
    bucket: default
    organization: influxdata
    token: BLABLABLA==
    urls:
    - http://influx2.monitoring.svc

With this Kubernetes version/platform (I've built a k3s cluster on Hetzner)

but I'm still stuck with the Telegraf pods in ContainerCreating
