无法在 Kubernetes 集群上验证 MongoDb

Question

当我尝试用mongo -u admin -p password -authenticationDatabase admin连接到运行在Kubernetes集群上的MongoDb时，我得到了这个错误：

{"mechanism":"SCRAM-SHA-1","speculative":false,"principalName":"admin","authenticationDatabase":"admin","remote":"192.168.65.3:47486","extraInfo":{},"error":"UserNotFound: Could not find user "admin" for db "admin""}}

下面是我用来创建MongoDb服务的yaml文件。

apiVersion: apps/v1
kind: StatefulSet
metadata:
name: mongodb-statefulset
spec:
serviceName: "mongodb-service"
selector:
matchLabels:
app: mongodb
template:
metadata:
labels:
app: mongodb
spec:
containers:
- name: mongodb
image: mongo
resources:
limits:
memory: "128Mi"
cpu: "500m"
ports:
- containerPort: 27017
env:
- name: MONGO_INITDB_ROOT_USERNAME
value: admin
- name: MONGO_INITDB_ROOT_PASSWORD
value: password
volumeMounts:
- mountPath: /data/db
name: data
volumeClaimTemplates:
- metadata:
name: data
spec:
accessModes: ["ReadWriteOnce"]
resources:

apiVersion: v1
kind: Service
metadata:
name: mongodb-service
spec:
type: LoadBalancer
selector:
app: mongodb
ports:
- port: 27017
targetPort: 27017

我什么都试过了，但还是没用。我感谢你的帮助。

尝试类似的操作，使用mongod作为命令

apiVersion: v1
kind: Service
metadata:
labels:
app: mongo
name: mongodb-service
spec:
type: NodePort
ports:
- name: "http"
port: 27017
protocol: TCP
targetPort: 27017
selector:
service: mongo

apiVersion: extensions/v1beta1
kind: Deployment
metadata:

spec:
replicas: 1
template:

labels:
service: mongo
name: mongodb-service

containers:
- args:
- mongod
- --smallfiles
image: mongo:latest
name: mongo
env:
- name: MONGO_INITDB_ROOT_USERNAME
value: admin
- name: MONGO_INITDB_ROOT_PASSWORD
