1、docker search --help（用于显示 Docker 搜索命令的帮助信息）

docker search --help 命令用于显示 Docker 搜索命令的帮助信息。这个命令会列出所有与 docker search 相关的选项和它们的用法说明，帮助你理解如何使用这个命令来搜索 Docker Hub 或其他配置的 Docker 仓库中的镜像。

[root@localhost ~]# docker search --helpUsage:  docker search [OPTIONS] TERMSearch Docker Hub for imagesOptions:-f, --filter filter   Filter output based on conditions provided--format string   Pretty-print search using a Go template--limit int       Max number of search results--no-trunc        Don't truncate output

2、docker pull（拉取镜像）

命令: docker pull
格式: docker pull 镜像名称[:tag]	# tag表示的镜像的标签，也可以理解为就是镜像的版本
# 默认拉取的是最新的redis镜像
docker pull redis			   
# 拉取redis7.0.10镜像，一个镜像到底存在哪些标签，需要上docker hub中进行查看
docker pull redis:7.0.10	   

执行效果如下所示：

[root@localhost ~]# docker pull redis:7.0.10
7.0.10: Pulling from library/redis
26c5c85e47da: Pull complete 
39f79586dcf2: Pull complete
