我使用 MongoDB Community Kubernetes Operator 建立了一个 Minikube-Cluster。要查看内容，我想设置一个连接到 Mongo-Cluster/ReplicaSet 的 mongo-express 实例。但是，如果我应用部署，容器总是会失败：

为了便于测试，我使用 docker-compose 启动 mango-express 并创建了一个端口转发来访问集群。
版本：
- MongoDB 集群：尝试了 4.2.6 和 4.4.3
- 蒙戈快递：0.54.0
这里是我用于 MongoDB 集群创建的部署/服务：
---
apiVersion: mongodb.com/v1
kind: MongoDB
metadata:
name: example-mongodb
spec:
members: 3
type: ReplicaSet
version: "4.4.3"
security:
authentication:
modes: ["SCRAM"]
users:
- name: mongoadmin
db: admin
passwordSecretRef: # a reference to the secret that will be used to generate the user's password
name: mongoadmin-password
roles:
- name: root
db: admin
scramCredentialsSecretName: my-scram
# the user credentials will be generated from this secret
# once the credentials are generated, this secret is no longer required
---
apiVersion: v1
kind: Secret
metadata:
name: mongoadmin-password
type: Opaque
stringData:
password: mongoadmin
这里是我用于 mongo-express 的 compose-file：
version: '3.8'
services:
mongo-express:
image: mongo-express
restart: on-failure
ports:
- 8081:8081
network_mode: host
environment:
ME_CONFIG_MONGODB_SERVER: localhost
ME_CONFIG_MONGODB_ADMINUSERNAME: mongoadmin
ME_CONFIG_MONGODB_ADMINPASSWORD: mongoadmin
问题是，如果我通过 docker-compose 使用 mongo-express 设置一个 mongo (4.4.3) 容器，一切正常......
有人知道发生了什么吗？
