docker search遇到：Error response from daemon: Unexpected status code 401(已解决)

1、问题描述：

在尝试通过docker查询镜像时，报了401（大概是无权限，没有认证）

# 10018318 @ Mrli in ~ [10:57:19]
$ docker search elasticsearch
Error response from daemon: Unexpected status code 401

经过一番查寻，定位到一个相似问题描述的文章：
https://forums.docker.com/t/error-response-from-daemon-unexpected-status-code-401/117194

大概意思就是目前是处于登录的状态，尝试去搜索时出现没有认证的提示

2、解决方式：

1、执行退出命令

# 10018318 @ Mrli in ~ [10:57:34] C:1
$ docker logout
Removing login credentials for https://index.docker.io/v1/

2、在执行之前的搜索命令，搜索成功
