Question

我用：

启动了我的redis docker容器

docker run --privileged=true -p 6379:6379 --name TestRedis -d redis

当我尝试在群集模式下使用Spring Redis时，我收到错误：

我需要做什么才能让它以群集形式运行？

Answer 1

当您刚刚运行redis Docker镜像时，它会根据其Dockerfile和内置配置启动，该配置没有打开群集。 Chris Tanner指向您的存储库使用相同的基本映像，但添加了配置以激活群集。但是，您需要克隆该存储库并构建映像，然后才能运行它。尽管docker run由于某种原因遗漏了映像名称，但是自述文件库在自述文件中有关于如何构建和运行它的良好说明。克隆回购，cd进去，然后执行此操作：

docker build -t testredis/redis-cluster .
docker run -i -t -p 7000:7000 -p 7001:7001 -p 7002:7002 -p 7003:7003 -p 7004:7004 -p 7005:7005 -p 7006:7006 -p 7007:7007 testredis/redis-cluster

这将使群集运行，您可以在7000端口将客户端指向它。

Answer 2

我认为您可以在dockerfile中添加启动脚本（shell脚本）并在CMD命令上调用它，该命令将使用一些redis.conf文件启动redis。在这个redis.conf中，你可以提到自定义配置如下

端口7000

群集启用是

cluster-config-file nodes.conf

cluster-node-timeout 5000

附带是

这将启动带有上述配置的redis实例

Answer 3

将此包含在 docker-compose 文件中以运行 redis 集群并连接到服务 docker 组件中的 redis-cluster:7000。
