istio-ingressgateway: сбой проверки готовности: сбой проверки HTTP с кодом состояния: 503

Question

Я пытаюсь настроить istio1.5.1 в кластере minicube kubernetes, я следую официальной документации Knative для настройки istio без внедрения коляски. Я сталкиваюсь с проблемой со службой istio ingress gateway, которая показывает внешний ip службы ingressgateway как. Я просмотрел другие ответы, опубликованные здесь, а также многие другие форумы, но ни один из них не помог в моем случае.

Использование minikube v1.9.1 с driver = none helm v2.16.5 kubectl v1.18.0

Я получаю следующий вывод для: kubectl get pods - namespace istio-system

kubectl get sv c --namespace istio-system

On описание входного модуля Я получаю предупреждение Ошибка проверки готовности: ошибка проверки HTTP с кодом состояния: 503

Может кто-нибудь помочь мне решить эту проблему. Спасибо!

Обновление с выводом после опробования ответа:

kubectl apply -f metallb.yaml

  podsecuritypolicy.policy/controller created
  podsecuritypolicy.policy/speaker created
  serviceaccount/controller created
  serviceaccount/speaker created
  clusterrole.rbac.authorization.k8s.io/metallb-system:controller created
  clusterrole.rbac.authorization.k8s.io/metallb-system:speaker created
  role.rbac.authorization.k8s.io/config-watcher created
  role.rbac.authorization.k8s.io/pod-lister created
  clusterrolebinding.rbac.authorization.k8s.io/metallb-system:controller created
  clusterrolebinding.rbac.authorization.k8s.io/metallb-system:speaker created
  rolebinding.rbac.authorization.k8s.io/config-watcher created
  rolebinding.rbac.authorization.k8s.io/pod-lister created
  daemonset.apps/speaker created
  deployment.apps/controller created

$ kubectl get pods -n metallb-system

  No resources found in metallb-system namespace.

После применения файла yaml он показывает, что все создано, но я не получаю ни одного модуля, развернутого в пространстве имен metallb-system.

Minikube может не предоставлять внешний IP или балансировщик нагрузки, который вам, возможно, придется использовать metalLB в мини-кубе.
