Use the following reference while configuring Add-Ons on your workload cluster.

antrea-tca-addon

Option Description
No SNAT Click the No SNAT toggle button to activate Source Network Address Translation (SNAT).

This option is for noEncap traffic mode only. By default, this option is not activated. In the noEncap mode, if the cluster’s POD CIDR is reachable from the external network, then this option can be deactivated.

In the networkPolicyOnly mode, antrea-tca-addon ignores SNAT. However, for the other modes, this option must be activated.

Traffic Encap Mode Determines how traffic is encapsulated. Select one of the following options:
  • encap: Internal Pod traffic is encapsulated and for external Pod network traffic, SNAT is performed.
  • noEncap: Internal Pod traffic is not encapsulated and for external Pod network traffic, SNAT is either performed or not based on the No SNAT setting in the preceding field.
    Note: Underlying network must be capable of supporting Pod traffic across IP subnets.

load-balancer-and-ingress-service(aka AKO)

Load-balancer-and-ingress-service add-on also known as AKO(AVI Kubernetes Operator) add-on.

Note:

  1. To install load-balancer-and-ingress-service(AKO) add-on for a Workload cluster, you must add AKOO(AVI Kubernetes Operator - Operator) on the Management cluster. For information about adding AKOO, see Add AVI Kubernetes Operator - Operator.

  2. Service engine group can not be shared by more than one TCA clusters, even if load-balancer-and-ingress-service(AKO) add-on is deleted from the original cluster or the original cluster is deleted already. To use a service engine group which was used by other cluster, delete the service engine group from Avi Controller UI and recreate it.

  3. To customize additional load-balancer-and-ingress-service(AKO) configurable fields and manage AKO objects(aviinfrasetting, gatewayclass, gateway) via the Custom Resources(CRs) tab, see Advanced configuration for load-balancer-and-ingress-service add-on.
