Describe the bug

Will flagger standalone control plane [without integrating with service mesh and ingress] allow us to use canary deployments with progressive traffic shifting?

As far I know, with only flagger control plane and k8s native resources, gradual traffic shifting is not possible.

For gradual traffic shifting, we need to either use kuma or nginx. Is my understanding correct?

I tried to create canary [Without integrating with any ingress and any service mesh] to my app with the integration with Prometheus for analysis, when I tried to add stepweight and other parameters for gradual traffic shifting. It was not happening.

To Reproduce

Nil

Expected behavior

Nil

Additional context

• Flagger version: 1.37.0
• Kubernetes version: 1.30.1
• Service Mesh provider: Nil
• Ingress provider: Nil
