docker下redis Could not connect to Redis at 127.0.0.1:6379

Question

我在docker中下载了 redis，配置完之后，使用 redis-cli 命令，报错 Could not connect to Redis at 127.0.0.1:6379

第一次用docker，下面步骤都是跟着书上做的，也不知道哪里出问题了。

1.下载 redis

sudo docker pull redis:latest

2.启动 redis 镜像 Container，开启 redis-server 持久化服务

sudo docker run --name redis-server -d redis redis-server --appendonly yes

3.启动 Redis 镜像 Container 作为客户端，连接 redis-server

sudo docker run --rm=true -it --link redis-server:redis redis /bin/bash

4.之后进入了 Container 内部的bash

REDIS_PORT_6379_TCP_PROTO=tcp
REDIS_PORT=tcp://172.17.0.2:6379
REDIS_NAME=/stupefied_bhaskara/redis

5.bash 中使用 redis-cli 报错

root@24f9eeb3e8e6:/data# redis-cli
Could not connect to Redis at 127.0.0.1:6379: Connection refused
Could not connect to Redis at 127.0.0.1:6379: Connection refused
