@juanitomint and I exchanged messages earlier over slack. Summary is that Pixie is not currently supported in environments where the host nodes are containers. The problem is that the container environment is not set-up for BPF.

Hey @oazizi000, could you please elaborate on the technical details? I am planning to play around with Pixie soon, and I'd like to use k3d as an environment, if possible. Could it be related to mounting the virtual /sys/fs/bpf kernel filesystem?

[SorsOps]

@oazizi000 I just recently came across this as well . My nodes are setup as proxmox vms on k3s , would they be affected by the issue with containers you mentioned above?

[ddelnano]

@SorsOps unfortunately they would be affected since k3s runs inside of a container.

[SorsOps]

I think https://docs.px.dev/installing-pixie/requirements#kubernetes-local-development-environments needs to be updated to explicitly say that k3s is not supported as it gives conflicting info

[ddelnano]

Sorry I may have misspoke with my previous comment. I haven't used k3s before and my earlier comment was based on my independent research. I trust our documentation more than my brief research, but let me confirm that.

@SorsOps for your k3s VMs are you able to confirm if k3s's components are running outside of a container?
