使用docker组合2个docker集装箱之间的连接
我有一个2 docker容器“restorecms_facade_1”（facade服务）和“restorecms_identity_1”（身份服务）运行在同一个网桥“restorecms_default”。
我在我的泊坞窗撰写文件中为主机名指定了“hostname：identity-srv”作为身份服务镜像
门面服务有5000端口暴露，它接受我的graphQL请求。 这个外观服务将把请求委托给在端口50051上运行的身份服务（dns name'identity-srv'），但是当前请求在门面服务上超时。
我的docker集装箱和新娘networking细节如下。
我甚至不能从门面服务ping身份服务（但其他方式是可能的）。
我在这里丢失了什么东西，还是我需要在门面服务上添加任何东西，以便连接通过身份服务？

主机名和ping：

我目前的docker-compose.yml（用于身份和门面服务）configuration如下：
identity: hostname: identity-srv image: xxx/identity-srv ports: - "50051:50051" depends_on: arangodb: condition: service_healthy links: - arangodb - kafka healthcheck: test: "exit 0" # Facade service facade: image: xxx/facade-srv ports: - "5000:5000" depends_on: identity: condition: service_healthy #resource: # condition: service_healthy links: - identity - kafka - elasticsearch - arangodb - redis
主机名只设置主机名“容器内”。 如果你想从另外一个ping它，你需要使用你在links部分使用的别名（默认为服务名称）。
ping identity如果你想使用identity-srv你可以使用这种方式的... links: - identity:identity-srv ...
