GitCommit is the commit hash when the binary was built

var (

var Version string

Version is the version of the compiled software

Functions

func GetVersionHandler

func GetVersionHandler() http.Handler

GetVersionHandler returns an HTTP handler that returns the version info

func IsDualStackEnabled

func IsDualStackEnabled(kubeClient kubernetes.Interface) bool

IsDualStackEnabled returns true if IPv4/IPv6 dual-stack is enabled in the Kubernetes cluster.

func IsEndpointSliceEnabled

func IsEndpointSliceEnabled(kubeClient kubernetes.Interface) bool

IsEndpointSliceEnabled returns true if EndpointSlice is enabled in the Kubernetes cluster.

func IsSupportedK8sVersion

func IsSupportedK8sVersion(kubeClient kubernetes.Interface) bool

IsSupportedK8sVersion returns true if the Kubernetes cluster version is supported by the operator.

func IsSupportedK8sVersionForGatewayAPI

func IsSupportedK8sVersionForGatewayAPI(kubeClient kubernetes.Interface) bool

IsSupportedK8sVersionForGatewayAPI returns true if the Kubernetes cluster version is supported by the operator.

func SetMetric

func SetMetric()

SetMetric is a one time call to expose the version info via prometheus metrics.

Types

type Info

type Info struct {
	// Version is the version of the FSM Controller.
	Version string `json:"version,omitempty"`

	// GitCommit is the git commit hash of the FSM Controller.
	GitCommit string `json:"git_commit,omitempty"`

	// BuildDate is the build date of the FSM Controller.
	BuildDate string `json:"build_date,omitempty"`
}

Info is a struct helpful for JSON serialization of the FSM Controller version information.

func GetInfo

func GetInfo() Info

GetInfo returns the version info
