falco ConfigMap diff in live vs desired state - using ArgoCD

[flickers]

Describe the bug
We are using the latest (4.5.1) falco helm chart to deploy falco to our clusters using ArgoCD
After a while (minute or so) we see a diff in the live falco configMap vs. desired configMap (rendered from the falco helm chart)
Mostly this is due to incorrect indentation but also due to different yaml scalars

How to reproduce it
Deploy falco using helm and then compare the falco configMap against the rendered falco configMap. Or deploy using ArgoCD

Expected behaviour
We expect the live and desired state to match after we deploy falco using helm and ArgoCD

Additional context

Hi @flickers, when the driver.kind is set to auto, falcoctl will automatically select the optimal driver for Falco. This selection will be updated in the Falco configmap. If you do not want this behavior then set the driver.kind to the desired driver:

charts/charts/falco/values.yaml

Line 184 in 7527d0f

kind: auto

Hey @flickers, falcoctl does not update anymore the falco configmap. For more info see: #735.

Let me know if this is still an issue for you.

[gvariola]

Can confirm that this is not an issue now.
