2、下载镜像

docker pull redis:latest

下载完成后即可查看镜像

3、查看镜像并创建redis和redis/data目录

docker images

root@kobe:/opt/software/redis# docker images
REPOSITORY                     TAG                 IMAGE ID            CREATED             SIZE
redis                          latest              1e70071f4af4        3 weeks ago         107MB

4、使用镜像创建容器

进入redis目录（redis目录下还有data目录，用于redis数据持久化的存储）

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

-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

5、进入容器操作redis

docker run -it redis:latest redis-cli -h 192.168.163.170

root@kobe:/opt/software/redis# docker run -it redis:latest redis-cli -h 192.168.163.170
192.168.163.170:6379> info
# Server
redis_version:4.0.6
redis_git_sha1:00000000
redis_git_dirty:0
redis_build_id:f1060815dd32471a
redis_mode:standalone
os:Linux 4.10.0-42-generic x86_64
.................
# Cluster
cluster_enabled:0

# Keyspace
192.168.163.170:6379> exit
root@kobe:/opt/software/redis# 

退出后，重新执行第五步即可重新进入容器操作redis容器

此时使用docker ps即可查看到运行的容器

root@kobe:/opt/software/redis# docker ps
