Pull request overview

Updates the Calico Enterprise v3.22-2 documentation for Service LoadBalancer IPAM to reflect how Service.spec.loadBalancerClass affects kube-controller IP assignment behavior.

Changes:

  • Documented that RequestedServicesOnly assignment also applies when Service.spec.loadBalancerClass is set to calico.
  • Added a note clarifying that Services with a non-calico loadBalancerClass are skipped regardless of assignIPs.


In certain cases you might not wish for $[prodname] to automatically assign IP addresses to your Service. This can be useful in case you have multiple Service IPAM solutions in your cluster.
LoadBalancer kube-controller is able to operate in two distinct modes ```AllServices``` in which $[prodname] assigns IP address to each Service in your cluster and ```RequestedServicesOnly``` in which $[prodname] only assigns IP addresses to Service with annotations mentioned above.
LoadBalancer kube-controller is able to operate in two distinct modes ```AllServices``` in which $[prodname] assigns IP address to each Service in your cluster and ```RequestedServicesOnly``` in which $[prodname] only assigns IP addresses to Service with annotations mentioned above or if `Service.spec.loadBalancerClass` is set to `calico`.

:::note

LoadBalancer controller considers the `Service.spec.loadBalancerClass`, it will skip assignment for Services where `loadBalancerClass` is set to a value other than `calico`, regardless of the `assignIPs` setting.
