Functions

func GetHostname

func GetHostname(hostnameOverride string) (string, error)

GetHostname returns OS's hostname if 'hostnameOverride' is empty; otherwise, it returns 'hostnameOverride'. In either case, the value is canonicalized (trimmed and lowercased).

func GetNodeCondition

func GetNodeCondition(status *v1.NodeStatus, conditionType v1.NodeConditionType) (int, *v1.NodeCondition)

GetNodeCondition extracts the provided condition from the given status and returns that. Returns nil and -1 if the condition is not present, and the index of the located condition.

func ParseNodeIPAnnotation

func ParseNodeIPAnnotation(nodeIP string) ([]net.IP, error)

ParseNodeIPAnnotation parses the `alpha.kubernetes.io/provided-node-ip` annotation, which can be either a single IP address or a comma-separated pair of IP addresses. Unlike with ParseNodeIPArgument, invalid values are considered an error.

func ParseNodeIPArgument

func ParseNodeIPArgument(nodeIP, cloudProvider string) ([]net.IP, []string, error)

ParseNodeIPArgument parses kubelet's --node-ip argument. If nodeIP contains invalid values, they will be returned as strings. This is done also when an error is returned. The caller then can decide what to do with the invalid values. Dual-stack node IPs are allowed if cloudProvider is unset or `"external"`.

func PatchNodeCIDRs

func PatchNodeCIDRs(ctx context.Context, c clientset.Interface, node types.NodeName, cidrs []string) error

PatchNodeCIDRs patches the specified node.CIDR=cidrs[0] and node.CIDRs to the given value.

func PatchNodeStatus

func PatchNodeStatus(c v1core.CoreV1Interface, nodeName types.NodeName, oldNode *v1.Node, newNode *v1.Node) (*v1.Node, []byte, error)

PatchNodeStatus patches node status.

func SetNodeCondition

func SetNodeCondition(c clientset.Interface, node types.NodeName, condition v1.NodeCondition) error

SetNodeCondition updates specific node condition with patch operation.
