Serving

Release Notes

🚨 Breaking or Notable

  • Activator uses TLS 1.3 as the minimum version when internal encryption is activated for communication with queue-proxy (#13887, @izabelacg)
  • Domain mapping controller logic is now merged with the Serving controller. Domainmapping webhook is merged with the Serving webhook. (#14082, @skonto)
  • DomainMapping/v1alpha1 is deprecated - use v1beta1 APIs (#14058, @dprotaso)

💫 New Features & Changes

  • A new flag is introduced queueproxy.resource-defaults that sets resource requests, limits for Queue Proxy when enabled (applies only to cpu and memory). (#14039, @skonto)
  • Activator now has a separate service account, reducing its privileges to the required minimum. (#14133, @davidhadas)
  • Queue proxy resources can be configured via annotations at the service level. The resource percentage annotation is now deprecated. (#14038, @skonto)

  • Fix activator load balancing when using unbounded concurrency and when you have two instances of a revision (#14028, @dprotaso)
  • Queue proxy metrics reporting period is now supported for both prometheus and opencensus. This allows fine-grained control of how often metrics are exported via a new config map attribute. (#14019, @skonto)
  • Tag to digest min TLS version is 1.2 and can be configured higher using the controller environment variable TAG_TO_DIGEST_TLS_MIN_VERSION and supports values "1.2" and "1.3" (#13962, @dprotaso)
