helm upgrade mongodb 失败并出现错误“无法构建 kubernetes 对象”

Question

In process of project initialization I have a command:

helm upgrade mongodb mongodb/mongodb --install --set replicaSet.enabled=true.

Which fails with error:

Release "mongodb" does not exist. Installing it now.
Error: unable to build kubernetes objects from release manifest: [resource mapping not found for name: "mongodb-arbiter" namespace: "" from "": no matches for kind "PodDisruptionBudget" in version "policy/v1beta1"
ensure CRDs are installed first, resource mapping not found for name: "mongodb-secondary" namespace: "" from "": no matches for kind "PodDisruptionBudget" in version "policy/v1beta1"
ensure CRDs are installed first]

Can you please suggest what to do?

Answer 1

The version of Kubernetes you are using is too new for your helm charts. Within the latest version of Kubernetes PodDisruptionBudget lives in policy/v1 and not policy/v1beta1 where your chart is looking for it.
