Version 1.27.15

What's new

Configuring wildcard DNS domains through Citrix ADC ingress controller

Wildcard DNS domains are used to handle requests for non-existent domains and subdomains. Now, Citrix ingress controller supports configuring wildcard DNS domains on a Citrix ADC. A new CRD wildcarddnsentry is introduced to support wildcard DNS domains.

For more information, see Configuring wildcard DNS domains through Citrix ADC ingress controller.

Open policy agent support for Kubernetes with Citrix ADC

Open policy agent (OPA) is an open source, general-purpose policy engine that unifies policy enforcement across different technologies and systems. Now, Citrix ingress controller supports OPA through the HTTP callout.

For more information, see Open policy agent support for Kubernetes with Citrix ADC.

Fixed issues

  • When distributed tracing is enabled for service mesh lite deployments, the service parameter was mandatory in the analytics configuration ConfigMap. If the service parameter is missing, distributed tracing was not working. This issue is fixed now.
  • Canary header values at Citrix ADC are not updated when the existing ingress is updated with new Canary header values using the Ingress annotation. This issue is fixed now.
  • For service mesh lite deployments, service group members were not binding earlier. This issue is fixed now.
  • During Citrix ingress controller boot-up pre-validation checks, tracebacks were happening while checking connection with Citrix ADC. This issue is fixed now.
  • Bot management policies were not getting configured on Citrix ADC VPX version 13.0 with the latest Citrix ingress controller versions. This issue is fixed now.
  • Citrix ingress controller now gracefully handles unauthorized access to the Kubernetes API server due to the token expiry.

Enhancements

  • A new environment variable OPTIMIZE_ENDPOINT_BINDING is introduced to enable or disable binding of back-end endpoints to a service group in a single API call. This variable is recommended when there are a large number of endpoints (pods) per application. This enhancement is applicable only for Citrix ADC release 13.0–45.7 and higher versions.
