Functions

func FindRancherIPInLabels

func FindRancherIPInLabels(labels map[string]string) (string, bool)

FindRancherIPInLabels looks for the `io.rancher.container.ip` label and parses it. Rancher 1.x containers don't have docker networks as the orchestrator provides its own CNI.

func GetHostname

func GetHostname(context.Context) (string, error)

GetHostname returns the hostname for docker

func GetMetadata

func GetMetadata() (map[string]string, error)

GetMetadata returns metadata about the docker runtime such as docker_version and if docker_swarm is enabled or not.

func GetTags

func GetTags(context.Context) ([]string, error)

GetTags returns tags that are automatically added to metrics and events on a host that is running docker.
