Kubernetes PodPreset不起作用 [英] Kubernetes PodPreset not working
问题描述
我想使用 PodPreset Kubernetes功能测试集群运行版本1.6.6. Kube-apiserver开始于(仅包括相关部分):
I wanted to play with PodPreset Kubernetes feature on my test cluster running version 1.6.6. Kube-apiserver is started with (included just the relevant part):
--storage-backend=etcd2
--admission-control ...,PodPreset
--runtime-config=settings.k8s.io/v1alpha1/podpreset
但是我仍然得到:

很明显，当我尝试通过kubectl提交资源时，它会失败.
And obviously when I try to submit my resource through kubectl it fails.
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Pod).有什么主意吗?
Cluster itself is running normally (I have multiple services and pods). Any idea?
推荐答案
"settings.k8s.io/v1alpha1" API端点默认在1.6.x中启用.因此，您无需在runtime-config参数中指定.
"settings.k8s.io/v1alpha1" API endpoint is enabled by default in 1.6.x. So you don't need to specify in runtime-config parameter.
是否可以尝试不在"runtime-config"参数中指定任何内容.您只需要已经在准入控制中使用PodPreset就可以了.
Can you try without specifying anything in "runtime-config" parameter. You just need PodPreset in admission-control, which you have already.
