kubernetes cassandra 操作员错误

Question

我在为 kubernetes 创建 cassandra 操作符时遇到错误。

# kubectl create -f example-cassandra-cluster.yaml 
error: unable to recognize "example-cassandra-cluster.yaml": no matches for cassandra.database.instaclustr.com/, Kind=CassandraCluster

example-cassandra-cluster.yaml是：

apiVersion: "cassandra.database.instaclustr.com/v1beta2"
kind: "CassandraCluster"
metadata:
name: "example-cassandra-cluster"
spec:
size: 3
version: "3.11"
pod:
resources:
  limits:
    memory: "512Mi"

有没有人遇到过这个错误？

Answer 1

这

apiVersion: "cassandra.database.instaclustr.com/v1beta2"

表示 CassandraCluster 种类

kind: "CassandraCluster"

取决于自定义资源定义。

该 CRD 必须在实例化其对象之前在集群中创建。
