neo4j的docker实例与express在本地机器上的通信

Question

设置:NEO4J官方docker图像

• neo4j_auth none
• 端口localhost:7474 localhost:7687
• 版本neo4j-community-4.3.3-unix.tar.gz

NODEJS图像

null

 let driver = neo4j.driver(
        envConf.dbUri,  
        neo4j.auth.basic(envConf.dbUserName, envConf.dbUserName)
        );

我可以通过http://localhost:7474/browser/远程到neo4j映像，所以它正在运行。

我不能使用服务器映像调用本地neo4j实例。

当我调用服务器映像中的API时，我得到以下错误

我已经搜索了一段时间的文档，任何想法都将是最受欢迎的！

Answer 1

我能够通过使用docker-compose实现通信。问题是这两个容器都充当独立的网络，我无法找到允许服务器与数据库通信的方法。运行docker-compose并在单个compose网络中构建这两个容器允许使用服务名称进行通信。

注意这是标签敏感的！！

docker-compose.yml

version: '3.7'

    lan:
