Functions

func Force

func Force(version string) error

Force forces the use of a specific version

func Update

func Update(client kubernetes.Interface, conf k8sconfig.Configuration) 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.

func Version

func Version() go_version.Version

Version returns the version of the Kubernetes apiserver

Types

type ServerCapabilities

type ServerCapabilities struct {
	// Patch is the ability to use PATCH to modify a resource
	Patch bool

	// UpdateStatus is the ability to update the status separately as a
	// sub-resource
	UpdateStatus bool

	// 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

	// FieldTypeInCRDSchema is set to true if Kubernetes supports having
	// the field Type set in the CRD Schema.
	FieldTypeInCRDSchema 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
