func GetNodeName ¶ added in v1.5.0

func GetNodeName() string

GetNodeName returns node name string for the given node in Kubernetes. It uses the NODE_NAME env variable by default, and falls back to HUBBLE_NODE_NAME if the former is missing. If both are missing, it will use the host name reported by the kernel. This value is used when watching for pods running on the node in Kubernetes.

NOTE: This is different from the Export equivalent for cases where nodes in kubernetes are named different from the desired node name in the JSON export.

func GetNodeNameForExport ¶

func GetNodeNameForExport() string

GetNodeNameForExport returns node name string for JSON export. It uses the HUBBLE_NODE_NAME env variable by default, and falls back to NODE_NAME if the former is missing. If both are missing, it will use the host name reported by the kernel
