spring-boot - 在 Docker 容器中运行的 SpringBoot 应用无法连接到同一台机器上托管的 Redis

Question

我在同一台物理机上安装了 Redis 和 Docker。

我正在尝试运行一个 Docker 容器，其中包含一个需要连接到 Redis 的 SpringBoot 应用程序。应用程序启动失败，出现以下错误:

如果我尝试使用 redis-cli 连接，它工作正常!如果我尝试启动我的应用程序，使用相同的配置，在机器上使用 java -jar 它工作正常!

Redis:Redis 5.0.3 (00000000/0) 64 位以独立模式运行端口:6379

docker : 版本:18.09.7 API版本:1.39 转版本:go1.10.4 Git 提交:2d0083d 建成时间:2019 年 8 月 16 日星期五 14:19:32 操作系统/架构:linux/amd64 实验:错误

在我的 redis.conf 中，我将 bind 属性注释掉并将保护模式设置为 no。

似乎通过使用 --net=host 标志运行 docker 容器可以解决问题。它现在可以访问主机上的其他内容(在本例中为 Redis)。
