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

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
