尝试连接 MongoDB Kubernetes 集群（使用 MongoDB 社区 Z301136395F0181737 创建）时，mongo-express 的身份验证问题

Question

我使用 MongoDB 社区 Kubernetes 操作员设置了 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：试过 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？

Answer 1

我已经从 mongo-express https://github.com/mongo-express/mongo-express/tree/v1.0.0-alpha.1的 alpha 版本构建了 docker 图像

这是图像uncl3mar1k/mongo-express:v1.0.0-alpha.1

它似乎与身份验证配合得很好，但我注意到它在分页方面存在问题。 （如果您有很多 collections 并尝试通过页面访问 go，您会注意到有关 collections 的数据没有变化）

更新：有一个更新的版本v1.0.0-alpha.3看起来所有问题都在这里修复了。 请看一下新图像： staslb/mongo-express:v1.0.0-alpha.3
