docker部署应用时超时解决

错误：

或

Get https://registry-1.docker.io/v2/: net/http: request canceled (Client.Timeout exceeded while awaiting headers)

解决方案：更换国内镜像服务器。

换了好几台，科大的，还有一些其他的，都是不行。决定试用镜像加速器。

登录阿里云控制台，产品中搜索镜像，选择镜像加速器，复制加速器地址。

将加速器地址，更新到/etc/docker/daemon.json中

{
"registry-mirrors": ["https://jvqgqnis.mirror.aliyuncs.com"]
}

居然又报下面错误：

curl https://registry-1.docker.io/v2/，发现需要认证。看来是auth.docker.io这个域名超时了。

Get https://registry-1.docker.io/v2/library/java/manifests/8: Get https://auth.docker.io/token?account=zhouyu629&amp;scope=repository%3Alibrary%2Fjava%3Apull&amp;service=registry.docker.io: net/http: request canceled (Client.Timeout exceeded while awaiting headers)

试试docker login

[root@localhost fpage]# docker login
Authenticating with existing credentials...
Login did not succeed, error: Error response from daemon: Get https://registry-1.docker.io/v2/: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)

果然不行。试用用chrome浏览auth这个域名，果然一会能打开，刷新一下又不行了，看来是不稳定。

白天在公司还行，家里网络不行，试了host和resovle，都不行。明天再到公司试下。

在公司网络下，果然可以了。看来家里网络还是有问题。

网络问题解决了，又出现一个新问题：no space left

docker info:
Storage Driver: overlay2

再 df -kh，看了下overlay空间不足

把/var/lib/docker 移到home，再做个快捷方式链接过去。

[root@localhost /]# service docker stop

[root@localhost /]# mv /var/lib/docker /home/
