У меня есть API, работающий на ECS Fargate
, который принимает GET
запросы метода.Я поставил перед ним конечную точку API Gateway
с интеграцией VPC_LINK
с NLB
в частной подсети.Когда я отправляю запрос GET
, используя url invoke, я получаю ошибку 404 page not found
.Я смущен, почему я получаю это.Я настроил каждый компонент - слушатель NLB, целевую группу, порты хоста и контейнера в своем определении задачи - на 8000/tcp
.Итак, я не уверен, почему эта ошибка происходит.Моя задача Fargate
также успешно выполняется и проходит все проверки работоспособности.Когда я тестирую контейнер локально, делая curl -X GET localhost/nmapscan:8000
, он работает нормально.Ниже приведены мои конфигурации в Terraform
, а также снимки экрана с консоли.
