Bug Report

Description

I tried deploying Cilium with "Method 5" but I got 3 problems, each probably related to Cilium CLI changes.

First, in cilium-install pod there was an error unknown flag: --set ipam.mode.
After debugging, I fixed it with replacing it from like this

- --set ipam.mode=kubernetes

to this

- --set
- ipam.mode=kubernetes

Next problems with cilium-install still was involving syntax errors. This time it was about not accepting ,. I escaped each one with \ and it was fixed too.

When cilium-install pod started working correctly and deploying other pods, I got error from cilium-agent pod:

unable to set memory resource limits" error="failed to set memlock rlimit: operation not permitted" subsys=daemon

Thanks to issues https://github.com/siderolabs/talos/issues/5948 https://github.com/cilium/cilium/issues/17883 I fixed it with adding another argument

- --set
- securityContext.privileged=true

and then it magically worked 🪄
