Я пытаюсь создать диаграмму Хелма для varni sh для развертывания / запуска в кластере Kubernetes. При запуске пакета helm, в котором есть образ varni sh из сообщества Docker, выдается ошибка
Readiness probe failed: HTTP probe failed with statuscode: 503
Liveness probe failed: HTTP probe failed with statuscode: 503
Поделились values.yaml, deployment.yaml, varnish-config.yaml, varnish.vcl.
Любое подходящее решение будет приветствоваться ....

# We usually recommend not to specify default resources and to leave this as a conscious

# resources, such as Minikube. If you do want to specify resources, uncomment the following
