Question

我正在将应用程序部署在azure容器实例（容器组）中。

我有3个Docker容器

web_api
redis
neo4j

我可以使用localhost:7474作为主机名来访问数据库，但是不能通过使用localhost作为主机名来访问redis。这是我在使用docker run命令在本地运行容器时遇到的相同问题。

注意：我不能使用docker-compose，因为我打算使用ACI。

通过本地主机访问redis需要对redis配置进行特殊调整。

看看

https://github.com/docker-library/redis/issues/45

和

https://github.com/luin/ioredis/issues/763

建议是通过redis主机名进行连接，您可以将此本地午睡直至redis主机名

无法从Azure容器实例（ACI）中的Web api容器连接Redis容器
