IPv4-Only Pods in Dual-Stack

[renyunkang]

If I've enabled dual-stack networking, how can I configure specific pods to use only IPv4 (single-stack)?

Is there a configuration method to achieve this, or is it currently unsupported?

@renyunkang Have you tried 'cni.projectcalico.org/ipAddrsNoIpam' annotation. More information here: https://docs.tigera.io/calico/latest/reference/configure-cni-plugins#requesting-a-specific-ip-address

Thank you for your response. @mazdakn "NoIpam" is not the desired outcome. I still want Calico to automatically manage IP addresses (IPAM), but I need a configuration option to specify which namespaces or pods should only use IPv4, instead of both IPv4 and IPv6, even with dual-stack enabled.
