Description Akriti Gupta 2023-03-02 14:08:35 UTC
Description of problem:
Add support for configuring Root FeartureGate via HCO CR 

Version-Release number of selected component (if applicable):


How reproducible:


Steps to Reproduce:
1.$  oc get hyperconverged kubevirt-hyperconverged -n openshift-cnv -o yaml | grep -A 8 "featureGates"

2.
3.

Actual results:
  featureGates:
    deployKubeSecondaryDNS: false
    deployTektonTaskResources: false
    enableCommonBootImageImport: true
    nonRoot: true

Expected results:
  featureGates:
    deployKubeSecondaryDNS: false
    deployTektonTaskResources: false
    enableCommonBootImageImport: true
    Root: False

Additional info:
The default value for root is expected to be false

This is being request due to the following PR, https://github.com/kubevirt/kubevirt/pull/8563

Comment 2 Simone Tiraboschi 2023-03-02 16:33:18 UTC
I see that the NonRoot FG is still there (although deprecated): https://github.com/kubevirt/kubevirt/blob/release-0.59/pkg/virt-config/feature-gates.go#L48

Being us already in BlockerOnly phase and being this a user facing change we will keep the current API for 4.13 (NonRoot FG with default=true) and we will properly expose the new one (Root FG with default=false) with a conversion on upgrades only for 4.14.

Verified against CNV-v4.14.0.rhel9-894:
root featuregate is now available and configurable via hco:
