const ClusterNameAnnotation = "federation.alpha.kubernetes.io/cluster-name"

ClusterNameAnnotation is the annotation which holds the name of the cluster that an object is associated with. If the object is not associated with any cluster, then this annotation is not required.

const FederationNameAnnotation = "federation.alpha.kubernetes.io/federation-name"

FederationNameAnnotation is the annotation which holds the name of the federation that a federation control plane component is associated with. It must be applied to all the API types that represent that federations control plane's components in the host cluster and in joining clusters.

	metav1.ObjectMeta

	// Spec defines the behavior of the Cluster.
	// +optional
	Spec ClusterSpec
	// Status describes the current status of a Cluster
	// +optional
	Status ClusterStatus
}

Information about a registered cluster in a federated kubernetes setup. Clusters are not namespaced and have unique names in the federation.

type ClusterCondition 

type ClusterCondition struct {
	// Type of cluster condition, Complete or Failed.
	Type ClusterConditionType
	// Status of the condition, one of True, False, Unknown.

	// (brief) reason for the condition's last transition.
	// +optional
	Reason string
	// Human readable message indicating details about last transition.
	// +optional
	Message string
}

ClusterCondition describes current state of a cluster.

type ClusterConditionType 

type ClusterConditionType string
const (
	// ClusterReady means the cluster is ready to accept workloads.
	ClusterReady ClusterConditionType = "Ready"
	// ClusterOffline means the cluster is temporarily down or not reachable
	ClusterOffline ClusterConditionType = "Offline"
)

These are valid conditions of a cluster.

type ClusterList 

type ClusterList struct {
	metav1.TypeMeta
	// Standard list metadata.
	// More info: https://git.k8s.io/community/contributors/devel/api-conventions.md#types-kinds
	// +optional
	metav1.ListMeta

	// List of Cluster objects.
	Items []Cluster
}

A list of all the kubernetes clusters registered to the federation

type ClusterPreferences added in v1.7.0 

type ClusterPreferences struct {
	// Minimum number of replicas that should be assigned to this cluster workload object. 0 by default.
	// +optional
	MinReplicas int64

	// Maximum number of replicas that should be assigned to this cluster workload object.
	// Unbounded if no value provided (default).
	// +optional
	MaxReplicas *int64

	// A number expressing the preference to put an additional replica to this cluster workload object.
	// 0 by default.
	Weight int64
}

Preferences regarding number of replicas assigned to a cluster workload object (dep, rs, ..) within a federated workload object.

type ClusterServiceIngress added in v1.7.0 

type ClusterServiceIngress struct {
	// Cluster is the name of the federated cluster
	Cluster string `json:"cluster"`

	Items []v1.LoadBalancerIngress `json:"items"`
}

Loadbalancer ingresses of a service within a federated cluster

type ClusterSpec 

type ClusterSpec struct {
	// A map of client CIDR to server address.
	// This is to help clients reach servers in the most network-efficient way possible.
	// Clients can use the appropriate server address as per the CIDR that they match.
	// In case of multiple matches, clients should use the longest matching CIDR.
	ServerAddressByClientCIDRs []ServerAddressByClientCIDR
	// Name of the secret containing kubeconfig to access this cluster.
	// The secret is read from the kubernetes cluster that is hosting federation control plane.
	// Admin needs to ensure that the required secret exists. Secret should be in the same namespace where federation control plane is hosted and it should have kubeconfig in its data with key "kubeconfig".
	// This will later be changed to a reference to secret in federation control plane when the federation control plane supports secrets.
	// This can be left empty if the cluster allows insecure access.
	// +optional
	SecretRef *api.LocalObjectReference
}

ClusterSpec describes the attributes of a kubernetes cluster.

type ClusterStatus 

type ClusterStatus struct {
	// Conditions is an array of current cluster conditions.
	// +optional
	Conditions []ClusterCondition
	// Zones is the list of availability zones in which the nodes of the cluster exist, e.g. 'us-east1-a'.
	// These will always be in the same region.
	// +optional
	Zones []string
	// Region is the name of the region in which all of the nodes in the cluster exist.  e.g. 'us-east1'.
	// +optional
	Region string
}

ClusterStatus is information about the current status of a cluster updated by cluster controller periodically.

type FederatedServiceIngress added in v1.7.0 

type FederatedServiceIngress struct {
	// List of loadbalancer ingress of a service in all federated clusters
	// +optional
	Items []ClusterServiceIngress `json:"items,omitempty"`
}

Annotation for a federated service to keep record of service loadbalancer ingresses in federated cluster

type ReplicaAllocationPreferences added in v1.7.0 

type ReplicaAllocationPreferences struct {
	// If set to true then already scheduled and running replicas may be moved to other clusters
	// in order to match current state to the specified preferences. Otherwise, if set to false,
	// up and running replicas will not be moved.
	// +optional
	Rebalance bool

	// A mapping between cluster names and preferences regarding a local workload object (dep, rs, .. ) in
	// these clusters.
	// "*" (if provided) applies to all clusters if an explicit mapping is not provided.
	// If omitted, clusters without explicit preferences should not have any replicas scheduled.
	// +optional
	Clusters map[string]ClusterPreferences
}

A set of preferences that can be added to federated version of workloads (deployments, replicasets, ..) as a json-serialized annotation. The preferences allow the users to express in which clusters they want to put their replicas within the mentioned workload objects.

type ServerAddressByClientCIDR 

type ServerAddressByClientCIDR struct {
	// The CIDR with which clients can match their IP to figure out the server address that they should use.
	ClientCIDR string
	// Address of this server, suitable for a client that matches the above CIDR.
	// This can be a hostname, hostname:port, IP or IP:port.
	ServerAddress string
}

ServerAddressByClientCIDR helps the client to determine the server address that they should use, depending on the clientCIDR that they match.
