Functions

func ClusterIngress added in v0.0.151 

func ClusterIngress(cluster *Cluster) (kubedef.IngressClass, error)

func DeleteAllRecursively 

func DeleteAllRecursively(ctx context.Context, cli *kubernetes.Clientset, wait bool, progress io.Writer, namespaces ...string) (bool, error)

func IngressOwnedBy added in v0.0.124 

func IngressOwnedBy(allFragments []*fnschema.IngressFragment, srv fnschema.PackageName) []*fnschema.IngressFragment

func MakeNamespace 

func MakeNamespace(env *schema.Environment, ns string) *applycorev1.NamespaceApplyConfiguration
