如何在同一实例上从一个容器向另一个容器发出 http 请求

Question

我正在 aws beanstalk 中运行一个多容器 docker 实例，我有 4 个容器在运行，一个 nginx 代理接收请求并将它们转发到正确的微服务和节点中接收这些请求的 3 个微服务。 但是现在我需要一个微服务在本地调用另一个，这可能吗？ 我尝试了所有可能的配置，我在容器、网络之间创建了一个链接，但我总是收到以下错误

getaddrinfo ENOTFOUND http://user:5003

这是实例的设置

Dockerrun.aws.json

 { "AWSEBDockerrunVersion": 2, "containerDefinitions": [ { "name": "auth", "image": "xxxxxx.amazonaws.com/auth-api", "hostname": "auth", "essential": false, "memory": 128, "links": [ "profile", "user" ] }, { "name": "profile", "image": "xxxxxx.amazonaws.com/profile-api", "hostname": "profile", "essential": false, "memory": 128 }, { "name": "user", "image": "xxxxxx.amazonaws.com/user-api", "hostname": "user", "essential": false, "memory": 128 }, { "name": "nginx", "image": "xxxxxx.amazonaws.com/nginx", "hostname": "nginx", "essential": true, "portMappings": [ { "hostPort": 80, "containerPort": 80 }, { "hostPort": 443, "containerPort": 443 } ], "links": [ "auth", "profile", "user" ], "memory": 64 } ] }

docker-compose.yml

Dockerfile（身份验证微服务）

Dockerfile（用户微服务）
