docker报错: x509: certificate has expired or is not yet valid

环境：最小化安装centos7

问题：docker 启动没问题，但是查询 镜像时报错

Error response from daemon: Get https://index.docker.io/v1/search?q=mysql&n=25: x509: certificate has expired or is not yet valid

最终发现问题是系统时间不同步

由于笔者是最小安装所以需要安装

 yum install -y ntpdate ntp

然后修改配置文件

vim /etc/ntp.conf

配置如下：

# For more information about this file, see the man pages
# ntp.conf(5), ntp_acc(5), ntp_auth(5), ntp_clock(5), ntp_misc(5), ntp_mon(5).

driftfile /var/lib/ntp/drift

# permit the source to query or modify the service on this system.

# be tightened as well, but to do so would effect some of
# the administrative functions.

启动

systemctl start ntpd

再一次查询系统时间 为当前时间即为成功

再次查询docker 镜像
