Functions

func AnnotateNode

func AnnotateNode(ctx context.Context, nodeName string, key, value string, c client.Client) error

AnnotateNode add annotation to a node

func AnnotateObject

func AnnotateObject(ctx context.Context, obj client.Object, key, value string, c client.Client) error

AnnotateObject adds annotation to a kubernetes object

func GetChrootExtension

func GetChrootExtension() string

func GetHostExtension

func GetHostExtension() string

func GetHostExtensionPath

func GetHostExtensionPath(path string) string

func IsCommandNotFound

func IsCommandNotFound(err error) bool

func IsExternalControlPlaneCluster

func IsExternalControlPlaneCluster(c client.Client) (bool, error)

IsExternalControlPlaneCluster detects control plane location of the cluster. On OpenShift, the control plane topology is configured in configv1.Infrastucture struct. On kubernetes, it is determined by which node the sriov operator is scheduled on. If operator pod is schedule on worker node, it is considered as external control plane.

func IsSingleNodeCluster

func IsSingleNodeCluster(c client.Client) (bool, error)

func LabelNode

func LabelNode(ctx context.Context, nodeName string, key, value string, c client.Client) error

LabelNode add label to a node

func ObjectHasAnnotation

func ObjectHasAnnotation(obj metav1.Object, annoKey string, value string) bool

ObjectHasAnnotation checks if a kubernetes object already contains annotation

func ObjectHasAnnotationKey

func ObjectHasAnnotationKey(obj metav1.Object, annoKey string) bool

ObjectHasAnnotationKey checks if a kubernetes object already contains annotation

func RemoveLabelFromNode

func RemoveLabelFromNode(ctx context.Context, nodeName string, key string, c client.Client) error

func Shutdown

func Shutdown()

Types

type CmdInterface

type CmdInterface interface {
	Chroot(string) (func() error, error)
	RunCommand(string, ...string) (string, string, error)
}

func New

func New() CmdInterface
