1、问题描述：从官网下载Tomcat镜像的时候发现报错报错信息如下
在这里插[root@localhost ~]# docker pull tomcat Using default tag: latest latest: Pulling from library/tomcat bb7d5a84853b: Pulling fs layer f02b617c6a8c: Pulling fs layer d32e17419b7e: Pulling fs layer c9d2d81226a4: Waiting fab4960f9cd2: Waiting da1c1e7baf6d: Waiting 1d2ade66c57e: Waiting ea2ad3f7cb7c: Waiting d75cb8d0a5ae: Waiting 76c37a4fffe6: Waiting error pulling image configuration: Get "https://production.cloudflare.docker.com/registry-v2/docker/registry/v2/blobs/sha256/b0/b0e0b0a92cf96022059ea14d7c0bee5f51cc856f21be4566d435125d6b261a6b/data?verify=1636529305-2qE5kf38lh5o9JENMJV9fiau%2Fd0%3D": dial tcp: lookup production.cloudflare.docker.com on 8.8.8.8:53: read udp 192.168.35.10:34006->8.8.8.8:53: i/o timeout 入代码片
2、问题解决
通过上网查资料发现是系统时间不同步发生的错误
通过以下命令进行时间同步操作即可
ntpdate time.windows.com
如果遇到命令不存在错误，先安装ntpdate命令
yum install -y ntpdate
