可以看到，版本是5.0.5，数据目录是/data，端口是6379。
下面创建容器
[root@localhost admin]# docker run --name some-redis -p 6379:6379 -d --privileged -v /usr/local/redis_data:/data redis redis-server --appendonly yes ff3ddf85b4a92958c416ad33dbd0553485639ca48c057966290c35f7687a2435 [root@localhost admin]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES ff3ddf85b4a9 redis "docker-entrypoint..." 10 seconds ago Up 9 seconds 0.0.0.0:6379->6379/tcp some-redis [root@localhost admin]# docker logs -f some-redis 1:C 30 Aug 2019 06:47:31.650 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo 1:C 30 Aug 2019 06:47:31.650 # Redis version=5.0.5, bits=64, commit=00000000, modified=0, pid=1, just started 1:C 30 Aug 2019 06:47:31.650 # Configuration loaded 1:M 30 Aug 2019 06:47:31.652 * Running mode=standalone, port=6379. 1:M 30 Aug 2019 06:47:31.652 # WARNING: The TCP backlog setting of 511 cannot be enforced because /proc/sys/net/core/somaxconn is set to the lower value of 128. 1:M 30 Aug 2019 06:47:31.652 # Server initialized 1:M 30 Aug 2019 06:47:31.652 # WARNING overcommit_memory is set to 0!

创建并启动成功。
参数解释：
docker run --name some-redis -p 6379:6379 -d --privileged -v /usr/local/redis_data:/data redis redis-server --appendonly yes --name：容器命名 -p：宿主机端口:容器内端口 -d：后台启动 --privileged：【chown: changing ownership of '.': Permission denied】授权 -v：将容器内的目录挂载到宿主机目录 redis：镜像名称 redis-server --appendonly yes：容器内执行redis-server命令，并打开持久化
在本地用redis客户端连接容器redis：
redis-cli.exe -h 192.168.192.128 -p 6379
