I set up a Minikube-Cluster with the MongoDB Community Kubernetes Operator.
To view the content i want to set up a mongo-express Instance which connects to the Mongo-Cluster/ReplicaSet. But if I apply the Deployment the Container always fails with:

For the ease of testing I used docker-compose to start mango-express and created a Port-Forwarding to access the cluster.
Versions:
MongoDB Cluster: tried 4.2.6 and 4.4.3
mongo-express: 0.54.0
Here the Deployment/Service I use for MongoDB Cluster creation:
---
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
And here the compose-file i use for mongo-express:
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
The thing is, that if I setup up a mongo (4.4.3) container with mongo-express via docker-compose everything works fine...
Does anybody have a clue whats going on?
I have build the docker image from the alpha version of mongo-express
https://github.com/mongo-express/mongo-express/tree/v1.0.0-alpha.1
Here is the image uncl3mar1k/mongo-express:v1.0.0-alpha.1
It seems to work well with authentication, but I noticed that it has an issue with pagening. (if you have a lot of collections and try to go through pages, you will notice that data about collections did not changes)
Update: there is a newer version v1.0.0-alpha.3 looks like all issues was fixed here. Please take a look to new image: staslb/mongo-express:v1.0.0-alpha.3
When starting my app, I get the following error:
error: MongoNetworkError: failed to connect to server [localhost:27017] on first connect [MongoNetworkTimeoutError: connection timed out

However, I can connect to the MongoDB service via MongoDBCompass and the Database connection tool in WebStorm, using the same connection string. "mongodb://localhost:27017/fmis"
I'm struggling to find the root cause to even try and solve it myself.
Update: as asked in the comments, I am running docker
I solved this by including the following in my connection configuration:
mongoose.connect(
db,
{
...
useUnifiedTopology: true //THIS SETTING
})
...
)
I used SpringBoot rest api and MongoDB. I have three different DataBases such as player-db, game-db and score-db. for each services I have DockerFiles.
when I run docker-compose up I've Getting an Error:
The error in docker-shell:

I do not know how to solve this problem.
I am beginner in Docker.
The problem here is with the network. Kindly understand that each container is a kind of a separate VM. Here, You are trying to connect to localhost. This will not work as each of the containers will resolve to it's own Loop back.
You can solve this in multiple ways:
Since all the containers are connected to the same docker network you can use container names to resolve respective ones. So here you can use db:27017 to connect to MongoDB.(Recommended)
Since you have port bonded all the containers you can use of the host machine instead of localhost. So if your host machine's private IP is 10.0.0.1 then use 10.0.0.1:27017 to connect to MongoDB.
Use host network, in this case, port binding instruction will be useless as it will be ignored and every service gets bonded automatically to their own port and you can use localhost to connect each of them (Not recommended)

I can use docker exec -it mysql-container bash command to enter mysql container and I can also use mysql -uh2t -p123456 to connect mysql.At the same time,I check the table,it was initialized,but SpringBoot App still can't connect to MySQL.
Can you help me,thanks in advance.
