我如何在docker-compose中获得容器以进行连接

Question

我正在尝试使docker-compose中的angular和nginx容器在google-compute vm实例（Debian OS）上互相交谈，但没有成功。这是我的docker-compose.yml：

version: '3'
services:
  angular:
    container_name: angular
    hostname: angular
    build: project-frontend
    ports:
      - "80:80"
        #network_mode: host
  nodejs:
    container_name: nodejs
    hostname: nodejs
    build: project-backend
    ports:
      - "8080:8080"
        # network_mode: host

我已经阅读了docs和许多诸如this之类的SO帖子，并且了解到angular应该试图在http://nodejs:8080/处找到节点，但是我得到了：

POST http://nodejs:8080/login/ net::ERR_NAME_NOT_RESOLVED

[我做docker networkk inspect时看到此

    {
        "Name": "project_default",
        "Id": "abe97d4c97e51806388ee36d19608c45c2e90033ee738588603623b9958375d5",

        "Scope": "local",
        "Driver": "bridge",
        "EnableIPv6": false,
        "IPAM": {
            "Driver": "default",
            "Options": null,
            "Config": [
                {
                    "Subnet": "172.24.0.0/16",
                    "Gateway": "172.24.0.1"
                }
            ]
        },
        "Internal": false,
        "Attachable": true,
        "Ingress": false,
        "ConfigFrom": {
            "Network": ""
        },
        "ConfigOnly": false,

我不确定还有哪些其他步骤可以帮助我进行调试。谢谢。

您需要确保它们在同一网络上。您可以通过在撰写文件的末尾添加以下几行来完成此操作

networks:
  default:
    external:
      name: project.local
