Kubernetes PodPreset不工作
Kubernetes PodPreset不工作
提问于 2017-06-27 22:58:10
我想在运行1.6.6版本的测试集群上使用PodPreset Kubernetes特性。Kube-apiserver的开头是(只包含相关部分)：
--storage-backend=etcd2
--admission-control ...,PodPreset
--runtime-config=settings.k8s.io/v1alpha1/podpreset
然而，我仍然得到：

显然，当我尝试通过kubectl提交我的资源时，它失败了。
error: error validating "pod-preset.yaml": error validating data: found invalid field resources for v1alpha1.PodPresetSpec; if you choose to ignore these errors, turn validation off with --validate=false
集群本身运行正常(我有多个服务和pods)。有什么想法吗？

1.6.x默认开启settings.k8s.io/v1alpha1 API端点。因此您不需要在运行时配置参数中指定。
你可以尝试不在“Can config”参数中指定任何东西吗？您只需要在准入控制中使用PodPreset，而您已经拥有了。

建议：
minikube stop
minikube start --extra-config=apiserver.runtime-config=settings.k8s.io/v1alpha1=true现在重试玩podpreset。这对我很管用。
