Using Operator-SDK v1.27.0 (from Makefile at the time)

Run Command

$ ./bin/operator-sdk create api --group bpfman --version v1alpha1 --kind TcxNsProgram --resource --controller --force --namespaced=true
Error: failed to create API: unable to inject the resource to "base.go.kubebuilder.io/v3": multiple groups are not allowed by default, to enable multi-group visit https://kubebuilder.io/migration/multi-group.html

Multiple Active Gateways

Summary

Submariner currently only allows a single gateway to be active at any one time in a given cluster. This enhancement proposes that there be an option to allow more than one gateway to be active in a given cluster to enhance both performance and resiliency. This feature is sometimes referred to as “active-active gateways”; however, the goal is to allow two or more active gateways to be used.

Proposal
