使用Rancher创建kubernetes集群失败

Question

我正在尝试使用 Rancher 在 VMWare vSphere 中创建 Kubernetes 集群。

Rancher：使用docker安装 安装选项（Docker 安装/Helm Chart）：Docker Install

当我尝试创建集群时，我遇到了这个错误：

Internal error occurred: failed calling webhook "rancher.cattle.io.secrets": failed to call webhook: Post "https://rancher-webhook.cattle-system.svc:443/v1/webhook/mutation/secrets?timeout=15s": no endpoints available for service "rancher-webhook"

如何解决？

Answer 1

创建命名空间时遇到同样的错误：

# kubectl create namespace minio-operator
Error from server (InternalError): Internal error occurred: failed calling webhook "rancher.cattle.io.namespaces.create-non-kubesystem": failed to call webhook: Post "https://rancher-webhook.cattle-system.svc:443/v1/webhook/validation/namespaces?timeout=10s": no endpoints available for service "rancher-webhook"

这对我有用：

# kubectl delete validatingwebhookconfigurations rancher.cattle.io
# kubectl delete pod -n cattle-system -l app=rancher-webhook
# kubectl delete secret -n cattle-system cattle-webhook-tls
# kubectl create namespace minio-operator
namespace/minio-operator created

这对我有用：

kubectl delete mutatingwebhookconfigurations rancher.cattle.io 
kubectl delete validatingwebhookconfigurations rancher.cattle.io
kubectl -n cattle-system delete service webhook-service
