Step4:运行容器

1
docker run -p 6379:6379 -v $PWD/data:/data -d redis:latest redis-server --appendonly yes

命令说明：
docker run：启动命令

-p 6379:6379 : 将容器的6379端口映射到主机的6379端口

-v $PWD/data:/data : 将主机中当前目录下的data挂载到容器的/data
- d ： 后台运行
redis-server --appendonly yes : 在容器执行redis-server启动命令，并打开redis持久化配置

Step5:使用docker ps命令查看容器是否启动：

CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                    NAMES
13c589ece0eb        redis:latest        "docker-entrypoint.s…"   8 seconds ago       Up 6 seconds        0.0.0.0:6379->6379/tcp   serene_golick

Step6:连接、查看容器:

使用redis镜像执行docker exec -it 13c589ece0eb redis-cli命令连接到刚启动的容器,主机IP为127.0.0.1:6379
