docker下载镜像报错：x509: certificate has expired or is not yet valid

docker pull centos:centos5
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
通过 ntpdate cn.pool.ntp.org更新系统时间

    "live-restore": true,
    "max-concurrent-downloads": 3,
    "max-concurrent-uploads": 5,
    "graph": "/data1/docker/storage/" # 镜像本地存储目录
}
