NOTE: This release is for informational purposes only. Please use releases v0.1.0-rc2 or above.

Changelog

Note This is the first beta1 (v0.1.0) release candidate. Subsequent release candidates are unlikely to include as many drastic changes.

Project name changed from Federation v2 to Kubernetes Cluster Federation (KubeFed for short)
- Helm chart renamed to kubefed
- docker image renamed to quay.io/kubernetes-multicluster/kubefed
- The managed label has been renamed from federation.k8s.io/managed to kubefed.k8s.io/managed
- The finalizer applied to federated resources has been changed from federation.k8s.io/sync-controller to kubefed.k8s.io/sync-controller
- API group changed from federation.k8s.io to kubefed.k8s.io
- FederatedCluster renamed to KubeFedCluster
- FederationConfig renamed to KubeFedConfig
- kubefedctl commands updated to reflect the rename
- All role, rolebindings, and service accounts are now prefixed with kubefed- instead of federation-
Core and federated api versions changed from v1alpha1 to v1beta1
Propagation status is now recorded for all federated resources.
KubeFedCluster
- Stores the API endpoint of a member cluster in field apiEndpoint instead of a cluster registry Cluster
- Stores the ca bundle in field caBundle instead of in a secret
- No longer supports insecure member clusters
Cluster references in placement are now objects instead of strings to ensure extensibility
The default KubeFed system namespace has been changed from federation-system to kube-federation-system. The kube- prefix is reserved for system namespaces and including it avoids having the KubeFed namespace conflict with a user namespace.
kubefedctl federate
- Supports conversion of yaml sourced from a file via --filename
- Supports conversion of yaml sourced from stdin via --filename -
- Supports skipping API resources when federating namespace contents via --skip-api-resources
API Resources have been updated to conform to Kubernetes API conventions
This release includes a pre-built kubefedctl binary for MacOS (darwin)

v0.0.10

v0.0.10 Pre-release

Pre-release

Changelog

Renamed the kubefed2 cli tool to kubefedctl.
Added conversion of a namespace and its contents to federated equivalents via kubefedctl federate ns <namespace> --contents.
kubefedctl disable now deletes a FederatedTypeConfig rather than setting propagationEnabled. It also waits for the sync controller to shut down, and optionally removes the federated type CRD.
Removal of the FederatedTypeConfig for namespaces now disables all namespaced sync controllers. Additionally, the FederatedTypeConfig for namespaces must exist prior to starting a namespaced sync controller.
The fedv2 controllers now watch only resources in member clusters that are managed by fedv2. This minimizes the resource utilization of the fedv2 control plane.
A new option - skipAdoptingResources - has been added to the controller manager. If set to true, resources existing prior to attempted propagation will be ignored by the sync controller.
The controller manager now exposes a health check endpoint to improve the reliability of detecting faults in the control plane.
The helm chart now defaults to 2 replicas of the controller manager to ensure that leader election handoff is enabled by default.
The helm chart in the host cluster now grants the fedv2 control plane minimal privileges.

v0.0.9

442e886

v0.0.9 Pre-release

Pre-release

Changelog

The controller manager is now configured with an api type - FederationConfig - rather than command-line options.
kubefed2 now discovers the scope and registry namespace of the control plane it is targeting via FederationConfig, and these options no longer have to be provided on the command line.
FederationConfig configures the scope of a control plane with the scope field instead of limitedScope. Valid values are Namespaced and Cluster.
Cross-cluster service discovery now works for multi-zone clusters. There is an update to FederatedClusters and ServiceDNSRecord API types wherein the zone field is changed to zones.
The cluster health check is now more robust, and will not switch a cluster to unhealthy until multiple checks have failed.
kubefed2 federate now supports the --enable-type flag
kubefed2 enable now succeeds if federation of the type is already enabled.
The controller manager now runs under its own SA rather than the default one for the namespace it runs in.
As a result of watching only labeled resources, unlabeled resources in unselected clusters will no longer be deleted.

v0.0.8

v0.0.8 Pre-release

Pre-release

Changelog

Helm is now the only supported method of deploying federation, and a chart archive will be provided with each release starting with this one.
The helm chart now correctly configures the controller manager with the minimal set of rbac permissions required to function.
The sync controller now applies a new finalizer (federation.k8s.io/sync-controller instead of federation.kubernetes.io/delete-from-underlying-clusters). This change in finalizer usage represents a breaking change with previous releases of federation since resources reconciled by previous releases will have the old finalizer. The old finalizer would need to be manually removed from a resource for that resource to be garbage collected after deletion.
The template for a FederatedNamespace is now sourced from the template field (like all other federated types) rather than the containing namespace.
kubefed2 federate has been updated to support output to yaml via -o yaml. YAML output requires a Kubernetes API endpoint to function, but can function even if federation is not deployed to the cluster.
kubectl get federatedcluster now lists the cluster status
The generated CRD schema of scalable resources (e.g. deployments, replicasets) now uses the correct type of boolean for the retainReplicas field (instead of bool).
