Discoverer image: gcr.io/heptio-images/gimbal-discoverer:v0.2.0

New and Improved

Advanded load balancing and routing features with the IngressRoute CRD

The initial implementation of the IngressRoute Custom Resource Definition (CRD) has been merged into Contour. Using this resource, you can define ingress rules that load balance requests to a specific Virtual Host across multiple backend clusters. See the design document for more information.

Discovered Service/Endpoints naming scheme changed

The naming scheme used when creating discovered Service and Endpoint resources in the Gimbal cluster has been changed. Once you update the Gimbal discoverers, they will re-discover the existing backend Services and Endpoints using new names. See the discovery naming conventions document for more information.

The Services and Endpoints discovered by the previous version will remain in the cluster, but they will not be updated once the new version of the discoverer is running.

The following command will list all Services and Endpoints that were discovered using the old naming scheme:

kubectl get svc,endpoints --all-namespaces -l gimbal.heptio.com/cluster

The following command will delete all Services and Endpoints in a specific namespace that were discovered by the old discoverers:

kubectl delete svc -n ${NAMSPACE} -l gimbal.heptio.com/cluster

IMPORTANT: Doing this will break any Ingress resources that are referencing these services.

Breaking changes

  • Discoverer configuration flag change: the --cluster-name flag has been removed and replaced by the --backend-name flag.
  • New naming scheme for discovered Services and Endpoints.

Action Required

  • Update Ingress resources to use the new Service names once the discoverer components are updated. This is required because the Service/Endpoint naming scheme has been updated, and old Service and Endpoints resources will not reflect any changes that occur in backend clusters.
