what happens in case there is no operator, should we have a fallback logic in kubearmor?

Yes, cluster name goes to "default".

@rootxrishabh i meant shouldn't we fetch cluster name from providers in case operator is not there?

[rksharma95]

@rootxrishabh can you please add args handling in operator helm chart? It should support any args list values.

[Prateeknandle]

Tested on both GKE and AWS, working as expected.

No, sry totally forgot this point, @rootxrishabh we should update cluster name in kubearmor, it should get updated based on conifgmap value.
