在ubuntu 14.04上安装docker 1.6版本后，不能使用阿里云提供的docker源，报FATA[0010] Error response from daemon: v1 ping attempt failed with error: Get https://registry.mirrors.aliyuncs.com/v1/_ping: dial tcp 10.157.230.35:443: i/o timeout. If this private registry supports only HTTP or HTTPS with an unknown CA certificate, please add `--insecure-registry registry.mirrors.aliyuncs.com` to the daemon's arguments. In the case of HTTPS, if you have access to the registry's CA certificate, no need for the flag; simply place the CA certificate at /etc/docker/certs.d/registry.mirrors.aliyuncs.com/ca.crt 。

　　在/etc/default/docker里增加INSECURE_REGISTRY="--insecure-registry=registry.mirrors.aliyuncs.com" ，然后service docker restart，还是报同样的错误。

　　报此错误的原因是docker源的配置问题，正确的配置路径和方法如下所示：

　　在/etc/default/docker里添加：

　　DOCKER_OPTS="--insecure-registry registry.mirrors.aliyuncs.com "

　　重启docker之后，就可以正常使用：

　　service docker restart
