Functions

func GetJsonFromUrl

func GetJsonFromUrl(url string, bearerToken string, caCert []byte, allowInsecure bool, readTimeout time.Duration, logger *log.Logger) (string, error)

func GetKubernetesApiUrlFromEnv

func GetKubernetesApiUrlFromEnv() (string, error)

GetKubernetesApiUrlFromEnv returns the k8s api url based on the content of standard env var :

KUBERNETES_SERVICE_HOST
KUBERNETES_SERVICE_PORT
in case the above ENV variables doesn't  exist the function returns an empty string and an error

func GetKubernetesInfo

func GetKubernetesInfo(l *log.Logger) (string, string, string)

func GetKubernetesLatestVersion

func GetKubernetesLatestVersion(logger *log.Logger) (string, error)

func GetOsUptime

func GetOsUptime() (string, error)
