我遇到一个非常基本的错误:
这是我运行
docker-ps时所拥有的:c:\>docker ps

docker push将本地镜像推送到本地注册表，并使用docker image remove命令删除了本地镜像，以避免任何混乱。 docker pull localhost:5000/dev/my-web:v1

kubectl命令而不是docker pull命令时出现连接被拒绝的错误。请帮忙。
其他说明:(1)我正在使用内置的Windows虚拟机管理程序(2)使用默认网络
最佳答案
好吧，Kubernetes找不到您的注册表。这取决于您的设置，但是适用于Windows的Docker在VM中运行，并且您未指定如何运行minikube，但很可能在另一VM中运行。因此，根据您的设置方式，这里可能有两个VM，每个VM可以或不能互相通信。localhost几乎永远不会与Kubernetes一起使用，因为在拉取镜像时，它始终解析为Kubernetes节点的本地IP。这意味着您将必须具有注册表和kubelet在完全相同的VM上提取镜像。
我只专注于使其与运行注册表的VM IP地址一起使用，并确保Kubernetes VM可以访问注册表VM IP地址。另外，请记住，在运行注册表时，在这种情况下，还必须公开容器端口5000附言您没有指定要运行的虚拟机监控程序？ VirtualBox？ VMware？您在使用桥接网络吗？仅限主机❓
