创建 "STDIN" 时出错：运行 skaffold dev 时发生内部错误
error when creating "STDIN": Internal error occurred while running skaffold dev
所以，我在 ubuntu 中使用 minikube v1.19.0，并在 kubernetes 中使用 nginx-ingress。我有两个节点文件：分别制作了 docker 图像的 auth 和 client
我得到了4个kubernetes cinfig文件如下：

实际上一切正常，直到我再次重新安装 minikube 并遇到此问题。
这里需要一些帮助。
您的日志清楚地表明入口版本警告存在问题。
Warning: extensions/v1beta1 Ingress is deprecated in v1.14+,
unavailable in v1.22+; use networking.k8s.io/v1 Ingress
您的集群版本可能高于 1.14+
这可能是您的 minikube 版本更新了
最新入口示例
apiVersion: "networking.k8s.io/v1beta1"
kind: "Ingress"
metadata:
name: "example-ingress"
spec:
ingressClassName: "external-lb"
rules:
- host: "*.example.com"
http:
paths:
- path: "/example"
pathType: "Prefix"
backend:
serviceName: "example-service"
servicePort: 80
lastet ingress apiversion 是：networking.k8s.io/v1beta1 您可以检查您的 lubernetes 集群的版本并验证哪个 API 集群支持。
https://kubernetes.io/blog/2020/04/02/improvements-to-the-ingress-api-in-kubernetes-1.18/
要检查您的 Kubernetes 支持哪个 API 版本，您可以 运行 :
kubectl api-versions
实际上我刚刚发现问题是在重新安装 minikube 时，Validating Webhook 没有被删除并因此产生了问题，应该使用以下命令将其删除。
kubectl delete -A ValidatingWebhookConfiguration ingress-nginx-admission
我发现在重新安装时忘记删除安装在清单中的这个 webhook，这导致了这个问题。
