Statefulset模板中缺少
我正试图使用minikube在容器中本地设置mongodb，下面是这个示例存储库：https://github.com/pkdone/minikube-mongodb-demo
我得到错误：
The StatefulSet "mongod" is invalid:
* spec.selector: Required value
* spec.template.metadata.labels: Invalid value: map[string]string{"environment":"test", "replicaset":"MainRepSet", "role":"mongo"}: `selector` does not match template `labels`
这是我的完整yaml文件：

spec.selector字段。
选择器是对应该与副本匹配的pod的标签查询计数它必须与pod模板的标签匹配。更多信息：https://kubernetes.io/docs/concepts/overview/working-with-objects/labels/#label-选择器
您需要添加spec.selector以匹配一个或多个标签。示例：
apiVersion: apps/v1
kind: StatefulSet
metadata:
name: mongod
spec:
serviceName: mongodb-service
replicas: 3
selector:
matchLabels:
role: mongo
template:
metadata:
labels:
role: mongo
environment: test
replicaset: MainRepSet
...
您使用的示例可能已经过时。以前的apps/v1beta1为spec.selector添加了一个默认值(如果为空(，但现在已经不是这样了。
选择器是对应该与副本匹配的pod的标签查询计数如果为空，则默认为pod模板上的标签。更多信息：https://kubernetes.io/docs/concepts/overview/working-with-objects/labels/#label-选择器
在apps/v1beta2和apps/v1中，应该显式设置它。
