What’s New in AKO Version 1.4.1

Key Changes in AKO 1.4.1

  • The field networkName in values.yaml is changed to vipNetworkList
  • AKO qualification for Kubernetes 1.19, 1.20, 1.21

End of Support

  • namespace sharding is deprecated starting from AKO version 1.4

Known Issues in AKO 1.4.1

  • With Avi Controller version 20.1.4, there are restrictions on the length of pool object names in the Controller. To comply with this change, the namespace/hostname/ingress names have to be adjusted accordingly. The current restriction on the controller is 128 characters with 119 characters being usable.
  • The current restriction on the number of DNS records supported per shared virtual service is 1000 on the Avi Controller. Hence if the shard size is chosen as SMALL, then the collective DNS records (hostnames) in a cluster must be less than 1000 for layer 7 ingress.
  • If a Hostrule CRD is used to program a GSLB FQDN in AKO that maps to a secure local FQDN, a redirect rule is not added for the GS FQDN.
  • In EVH mode, status IP updates could be inconsistent if multiple Ingresses share the same hostname.
