我遇到了一个奇怪的问题,docker pull工作了,但当使用kubectl创建或应用-f与kind cluster时,得到以下错误信息

解决方案:

我在OpenShift上遇到了类似的问题(我想)–我可以拉动镜像,但我无法推送或让k8s拉动它们。为了解决这个问题,我不得不更新了docker配置,地址是 /etc/sysconfig/docker 并将注册表添加为不安全的注册表。对于openshift,需要使用默认的路由。

OPTIONS=' <some existing config stuff here> --insecure-registry=<fqdn-of-your-registry>'

然后 systemctl restart docker 以使更改生效。

你可能还需要在kubernetes中用你的凭证创建一个docker pull secret来允许它访问注册表。详细内容 此处
