Docker for Desktop MacOS: kernel tracing is not available: stat /sys/kernel/debug/tracing: no such file or directory

[dj-wasabi]

I am trying to run coroot locally in my Docker for Desktop on Mac, to experiment a bit. I have the following error:

I followed the https://coroot.com/docs/coroot-community-edition/getting-started/installation installation steps. All is working/running:

$ kubectl -n coroot get pods

Is there a way that I can change the daemonset in a way to have it running? So I can at least experiment a bit with it?
Thanks in advance!

@dj-wasabi, thanks for the report! I've reproduced the issue.
Running the agent in Docker Desktop is theoretically possible, but we'd need to make some tweaks to the code:

• /sys/kernel/debug is not mounted from the host (seems like the system tries to mount it from the Mac host instead of the Linux VM).
• To retrieve container metadata, the agent should use Dockerd through the /run/guest-services/docker.sock

Until these adjustments are made, it's safe to consider Docker Desktop as unsupported.
