将docker更新至1.12后无法拉/推图像

私有注册表在docker 1.10.3的基础上运行良好，但是在docker更新到1.12.0之后我无法拉/推映像。

我已经将/ etc / sysconfig / docker修改为：

OPTIONS='--selinux-enabled=true --insecure-registry=myip:5000'

要么

OPTIONS='--selinux-enabled=true --insecure-registry myip:5000'

但是当我执行拉/推，我得到了这个错误：

$ docker pull myip:5000/cadvisor
Using default tag: latest
Error response from daemon: Get https://myip:5000/v1/_ping: http: server gave HTTP response to HTTPS client

当我将docker改回1.10.3时，它仍然可以正常工作，如下所示：

$ docker pull myip:5000/cadvisor
Using default tag: latest
Trying to pull repository myip:5000/cadvisor ...

在以调试模式重新启动docker守护程序后，下面列出了重现我的问题时的守护程序日志：

而且，我只是运行一个简单的命令来启动私有注册表进行测试，默认情况下，其他所有操作都是：

docker run -d -p 5000:5000 --restart=always --name registry -v 'pwd'/data:/var/lib/registry registry:2

没有配置代理。总之，这只是一个安静的示例测试环境。

回答：

我遇到过同样的问题。

这对我有帮助：

  • *

{ "insecure-registries":["myregistry.example.com:5000"] }

  • 重新启动docker daemon

sudo /etc/init.d/docker restart
