Issues Resolved in
AKO
 1.13.1

  • AKO
     crashes when an Ingress is configured with a HostRule object that has the
    analyticsPolicy.logAllHeaders
     setting enabled.
  • AKO
     does not configure the
    Error Page Profile
     for an EVH parent shared virtual service when
    errorPageProfile
     is set in a matching HostRule object.
  • AKO
    -Gateway does not create a virtual service if Gateway has multiple listeners with the same hostname but a different port and a single HTTP route is attached to it.

Key Changes in
AKO
 1.13.1

  • The
    L4Settings.defaultDomain
     field in Helm values.yaml is deprecated in favour of the newly introduced
    NetworkSettings.defaultDomain
     field. The value in the latter will be preferred for populating
    defaultDomain
     field in ConfigMap. For more information, see NetworkSettings.defaultDomain in the
    Tunables for
    AKO
     topic.
  • AKO
     now accepts Gateway with some valid and some invalid listeners.
  • AKO now allows the creation/updation of HTTPRoute and Gateway in any order. For more information, see Resource Creation in the
    Gateway API - v1
     topic.
  • HTTPRoute deletion will not update Gateway listener status with
    Virtual service deleted
    .
  • If the Secret specified in the TLS section does not exist,
    AKO
     will invalidate the Gateway listener and not generate any configuration corresponding to it. If an existing Secret is deleted, then Parent VS configurations corresponding to it will be deleted.

Known Issue in
AKO
 1.13.1

  • If the tenant name contains invalid characters outside the range of (0-9/A-Z/a-z/-/_),
    AKO
     fails to create shared SNI parent VS VIPs.
