Runtime defines an interface that can be implemented for various container runtime environments (docker, containerd, etc.)

var SelectedRuntime Runtime = docker.Docker{}

SelectedRuntime is a runtime (pun intended) variable determining the selected runtime

func GetRuntime

func GetRuntime(rt string) (Runtime, error)

GetRuntime checks, if a given name is represented by an implemented k3d runtime and returns it
