Functions ¶
func DisableLeasesResourceLock ¶
func DisableLeasesResourceLock()
func Update ¶
func Update(client kubernetes.Interface, apiDiscoveryEnabled bool) error
Update retrieves the version of the Kubernetes apiserver and derives the capabilities. This function must be called after connectivity to the apiserver has been established.
Discovery of capabilities only works if the discovery API of the apiserver is functional. If it is not available, a warning is logged and the discovery falls back to probing individual API endpoints.
Types ¶
type ServerCapabilities ¶
type ServerCapabilities struct {
// MinimalVersionMet is true when the minimal version of Kubernetes
// required to run Cilium has been met
MinimalVersionMet bool
// EndpointSlice is the ability of k8s server to support endpoint slices
EndpointSlice bool
// EndpointSliceV1 is the ability of k8s server to support endpoint slices
// v1. This version was introduced in K8s v1.21.0.
EndpointSliceV1 bool
// LeasesResourceLock is the ability of K8s server to support Lease type
// from coordination.k8s.io/v1 API for leader election purposes(currently only in operator).
// https://kubernetes.io/docs/reference/generated/kubernetes-api/v1.18/#lease-v1-coordination-k8s-io
//
// This capability was introduced in K8s version 1.14, prior to which
// we don't support HA mode for the cilium-operator.
LeasesResourceLock bool
}
ServerCapabilities is a list of server capabilities derived based on version, the Kubernetes discovery API, or probing of individual API endpoints.
func Capabilities ¶
func Capabilities() ServerCapabilities
Capabilities returns the capabilities of the Kubernetes apiserver
