    安装，可以设置key和secret，映射数据目录和配置目录

    1. docker run -p 9000:9000 --name minio \
    2. -d --restart=always \
    3. -e "MINIO_ACCESS_KEY=admin" \
    4. -e "MINIO_SECRET_KEY=admin123456" \
    5. -v /home/data:/data \
    6. -v /home/config:/root/.minio \
    7. minio/minio server /data

    通过ip:9000可以查看
