Functions

func GetEnvironmentProperties

func GetEnvironmentProperties() map[string]string

func GetK8SApiserverURLFromKubeConfig

func GetK8SApiserverURLFromKubeConfig() (string, error)

GetK8SApiserverURLFromKubeConfig returns apiserver URL from kubeconfig. The apiserver URL is expected to be publicly unique identifier of the Kubernetes cluster. In case the kubeconfig does not exists, this identifier can be obtained for pods from kube-system namespace. Kubelet will populate env KUBERNETES_SERVICE_HOST and KUBERNETES_SERVICE_PORT for Pods deployed in kube-system namespace, which can be used to generate apiserver URL from `GetConfig()`.

func InitAppInsights

func InitAppInsights(appinsightsId, appVersion string)

func KernelVersion

func KernelVersion(ctx context.Context) (string, error)

func ShutdownAppInsights

func ShutdownAppInsights()

func TrackPanic

func TrackPanic()

TrackPanic function sends the stacktrace and flushes logs only in a goroutine where its call is deferred. Panics in other goroutines will not be caught by this recover function.
