在k8s上安装calico时报错: no matches for kind “PodDisruptionBudget“ in version “policy/v1“

在k8s上安装calico时报错:

unable to recognize “calico.yaml”: no matches for kind “PodDisruptionBudget” in version “policy/v1”

这是k8s不支持当前calico版本的原因, calico版本与k8s版本支持关系可到calico官网查看:

https://projectcalico.docs.tigera.io/archive/v3.20/getting-started/kubernetes/requirements

最后, 由于k8s和其插件都迭代很快, 安装k8s的所有插件都要注意版本是否匹配!!!
