Eventing

WARNING: Release 0.6.0 has a critical bug causing the Broker to drop messages. Please use 0.6.1 or later.

Action Required

The in-memory-channel ClusterChannelProvisioner will be deleted in release 0.7, replaced by the in-memory provisioner. Please migrate all in-memory-channel Channels to in-memory. #1044 #1057
Trigger's BrokerExists condition is now called Broker. #1071
The Kafka dispatcher StatefulSet has been scaled to 0 replicas and replaced with a Deployment. Please delete the StatefulSet eventing-sources/kafka-channel-dispatcher after upgrading to 0.6. #972 #1141
CronJobSource and ContainerSource are now installed as part of the Eventing release instead of Eventing Sources. #1092 #1099
The in-memory ClusterChannelProvisioner now depends on the config-tracing ConfigMap installed by Eventing. Eventing should be installed first. If the in-memory CCP is installed first, the in-memory dispatcher will crashloop until Eventing is installed. #1199
CronJobSource now uses /apis/v1/namespaces//cronjobsources/ as the CloudEvents Source for all events. This replaces the previous /CronJob value. #1209

A new EventType CRD has been introduced to store the event types that can be consumed from the eventing mesh. #1105
Upon creating a CronJobSource or ApiServerSource, its EventType will be added to the Registry. #1146 #1201
Istio is no longer a dependency of Eventing components. Eventing will still work if Istio is present. #294
A new ApiServerSource CRD has been introduced that emits events when Kubernetes objects change. #1108
All Channels now support tracing. Tracing is configured by the config-tracing ConfigMap. #1199 #1203 #1204 #1231
All controller reconcilers now expose metrics. #1200
The ContainerSource now provides additional Kubernetes Events and resource Conditions to assist in debugging knative/eventing-contrib#186

Triggers now use paths instead of hosts for routing to subscribers, removing the need to create Kubernetes Service and Istio VirtualService objects.
Existing Service and VirtualService objects owned by Triggers will not be deleted proactively. They will be cleaned up by Kubernetes GC when their owning Trigger is deleted. #1045
Channels using the in-memory-channel provisioner will now have a Deprecated condition. #1062
All channels now use Kubernetes Service objects of type ExternalName instead of Istio VirtualService objects. #1044 #1058 #1074 #1099
Eventing data plane components no longer force the Istio sidecar to be injected. #1119

Broker's Ready condition is now only True when its constituent pieces are also Ready. #1064
Trigger's Ready condition is now only True when its constituent pieces are also Ready. The Broker condition is now called BrokerExists. #1071
Channel's subscriber array now uses uid as a patch key. The ref field is now deprecated. #1057
Controllers now have the proper finalizer RBAC permissions. #1086 #1089 #1120
Webhook Controller now binds to an unprivileged port. #1130
Subscriptions and Triggers watch and track their subscribers so subscriber changes are noticed more quickly. #1149
