Docker 构建 Redis

一、单节点redis

1）拉取镜像

docker pull redis:5

2.1）方法一：直接创建容器

docker run \
  -p 6379:6379 \
  --restart=always \
  --name some-redis \
  -v /mnt/redis/data:/data \
  --network=my-network \
  --network-alias=redis-alias \
  -e TZ=Asia/Shanghai \
  -d redis:tag redis-server --appendonly yes --requirepass "my-secret-pw"

some-redis：创建后的容器名称（此处我修改为 redis）
data：挂载数据路径
network：非必须，要加入的网络
network-alias：被必须，在网络中的别名
TZ：时区
tag：指定 redis 版本（此处我修改为5）
requirepass：登陆密码

2.2）方法二：自定义配置

创建映射文件夹并把自定义的 redis.conf 复制进去

mkdir -p /myredis/conf/

redis.conf 主要修改这几点

bind 0.0.0.0
protected-mode no
daemonize no
requirepass 你的密码

然后创建容器

docker run -d -p 6379:6379 -v /myredis/conf/redis.conf:/usr/local/etc/redis/redis.conf --name redis --restart=always redis:5 redis-server /usr/local/etc/redis/redis.conf --appendonly yes

3）测试连接

二、redis单机集群

1. 创建redis-cluster.yaml文件，注意修改ip
