func DeploymentInMesh

func DeploymentInMesh(r *resource.Instance, c analysis.Context) bool

DeploymentinMesh returns true if deployment is in the service mesh (has sidecar)

func ErrorLine

type ScopedFqdn

type ScopedFqdn string

func NewScopedFqdn

func NewScopedFqdn(scope string, namespace resource.Namespace, host string) ScopedFqdn
