当我使用docker-compose运行时，Express网关总是返回Bad gateway

Question

我尝试使用带有Docker的Express Gateway作为每个微服务的容器。到目前为止，它在本地测试中表现得非常好。通过实现EG来使用Docker时出现了问题。我不知道问题出在哪里。在LOG_LEVEL = debug上没有完整的描述。在此之前，我使用了没有EG的docker，然后与其他微服务进行了通信。请帮帮忙。

gateway.config.yml

我需要你的帮助。感谢您审阅此问题。

Answer 1

您的auth-service和crud-service的URL不应该是localhost。它应该是：

serviceEndpoints:
  authService:
    url: 'http://api-auth:3003'
  crudService:
    url: 'http://api-crud:3004'

api-auth和api-crud是您的docker-compose网络中这两个容器的主机名。
