func IsTypicalKubernetesEnv

func IsTypicalKubernetesEnv() bool

Since 1.13 you can disable service environment variables [1] thanks to the pull request to add the enableServiceLinks setting [2] but default kubernetes API server ones [3] are still always exported in container kubelet. This is why it's a rather stable way to determine quickly if you are running inside a kubernetes cluster. Of course it's possible to remove that variable from the environment to create a false negative and to add such variable in any environment to create a false positive but it's a bit unlikely.
