环境:centos 7
程序:docker
下载镜像报错:
# docker pull centos
Pulling repository centos
FATA[0004] Get https://index.docker.io/v1/repositories/library/centos/images: x509: certificate has expired or is not yet valid
这种错误,一般都是本地系统时间错误导致报错证书过期,所以先查看本地系统时间
# date "+%Y-%m-%d" #系统时间2月15日,而正确时间应该是4月17日,所以很大可能就是该原因
2015-02-15
解决:
# ntpdate cn.pool.ntp.org #同步一下时间
17 Apr 17:40:45 ntpdate[32206]: step time server 202.112.29.82 offset 5262859.193967 sec
# date "+%Y-%m-%d" #时间同步成功
2015-04-17
# docker pull centos #成功下载镜像,问题解决
