方法一、docker pull redis:3.2
查找Docker Hub上的redis镜像
runoob@runoob:~/redis$ docker search redis

这里我们拉取官方的镜像,标签为3.2
runoob@runoob:~/redis$ docker pull redis:3.2
等待下载完成后，我们就可以在本地镜像列表里查到REPOSITORY为redis,标签为3.2的镜像。
runoob@runoob:~/redis$ docker images redis
REPOSITORY TAG IMAGE ID CREATED SIZE
redis 3.2 43c923d57784 2 weeks ago 193.9 MB
方法二、通过 Dockerfile 构建
创建Dockerfile
首先，创建目录redis,用于存放后面的相关东西。
runoob@runoob:~$ mkdir -p ~/redis ~/redis/data
data目录将映射为redis容器配置的/data目录,作为redis数据持久化的存储目录
进入创建的redis目录，创建Dockerfile
FROM debian:jessie
# add our user and group first to make sure their IDs get assigned consistently, regardless of whatever dependencies get added
RUN groupadd -r redis && useradd -r -g redis redis

RUN mkdir /data && chown redis:redis /data
VOLUME /data
WORKDIR /data
COPY docker-entrypoint.sh /usr/local/bin/
ENTRYPOINT ["docker-entrypoint.sh"]
EXPOSE 6379
CMD [ "redis-server" ]
通过Dockerfile创建一个镜像，替换成你自己的名字
runoob@runoob:~/redis$ docker build -t redis:3.2 .
创建完成后，我们可以在本地的镜像列表里查找到刚刚创建的镜像
runoob@runoob:~/redis$ docker images redis
REPOSITORY TAG IMAGE ID CREATED SIZE
redis 3.2 43c923d57784 2 weeks ago 193.9 MB
使用redis镜像
运行容器
runoob@runoob:~/redis$ docker run -p 6379:6379 -v $PWD/data:/data -d redis:3.2 redis-server --appendonly yes
43f7a65ec7f8bd64eb1c5d82bc4fb60e5eb31915979c4e7821759aac3b62f330
runoob@runoob:~/redis$
命令说明：
-p 6379:6379 : 将容器的6379端口映射到主机的6379端口
-v $PWD/data:/data : 将主机中当前目录下的data挂载到容器的/data
redis-server --appendonly yes : 在容器执行redis-server启动命令，并打开redis持久化配置
查看容器启动情况
runoob@runoob:~/redis$ docker ps
CONTAINER ID IMAGE COMMAND ... PORTS NAMES
43f7a65ec7f8 redis:3.2 "docker-entrypoint.sh" ... 0.0.0.0:6379->6379/tcp agitated_cray
连接、查看容器
使用redis镜像执行redis-cli命令连接到刚启动的容器,主机IP为172.17.0.1
runoob@runoob:~/redis$ docker exec -it 43f7a65ec7f8 redis-cli
