I have below mongodb configuration in docker-compose.yml file -

volumes:
- ~/.m2:/root/.m2
depends_on:
- "kafka"
- "redis"
- "mongodb"
networks:
- app-tier
Whenever I run docker-compose my app infrastructure giving below error -
error connecting to host: could not connect to server: server selection error: server selection timeout, current topology: { Type: Single, Servers: [{ Addr: localhost:27017, Type: Unknown, Last error: connection() error occured during connection handshake: dial tcp 127.0.0.1:27017: connect: connection refused }, ] }
Inside application I am not even trying to connect mongodb, I am just trying to set up my application first using docker-compose
Am I missing anything here?
Something in infrastructure image is trying to connect to mongodb. localhost is likely a default host, if you didn't set it explicitly. You need to find out who is that and set host name to mongodb

I know this should have been a straight-forward issue as I did it before (but forgot how): I have my MongoDB running on a docker container as a service in my docker-compose that includes an API built with FastAPI. I'm able to connect to the database from my api container with the following code:
from pymongo.mongo_client import MongoClient
from pymongo.server_api import ServerApi
client = MongoClient('mongodb://USERNAME:PASSWORD#mongo:27017/', server_api=ServerApi('1'),
serverSelectionTimeoutMS=5000)
client.server_info()
Now when I try to do the same from a Jupyter notebook on my local machine, I get this error:
ServerSelectionTimeoutError: mongo:27017: [Errno 8] nodename nor servname provided, or
not known, Timeout: 5.0s, Topology Description: <TopologyDescription id:
63b6adb8b6aabb1624b50879, topology_type: Unknown, servers: [<ServerDescription

[Errno 8] nodename nor servname provided, or not known')>]>
This is my docker-compose configuration that used to work just fine when I was able to connect to my mongodb from local (so I don't think there is an issue here):

I am currently unable to connect to mongo when I run docker-compose, I keep on getting the error below

Now, I'm able to connect with my mongo database from my local windows machine through mongodb client but my server container is not able connect with database container.
I'm using following connection URI on my server to establish a connection:
mongodb://myusername:mypassword#database:7000/mydatabase
It must be noted that on my local machine I'm using the same URI to connect successfully with the database, the only difference is that I'm using localhost instead of database (container name) on my local machine.
Can you please tell me what I'm doing wrong here?
I'm trying to configure my docker to pgadmin4 in my nest js project, to do the backend, but when i try connect, show this message "Unable to connect to server:
could not connect to server: Connection refused
Is the server running on host "localhost" (127.0.0.1) and accepting"
I already tried configure the docker-compose.yml with pgadmin configurations, network configurations and
my docker-compose.yml
version: '3'
services:
db:
image: postgres
environment:
POSTGRES_PASSWORD: "12345678"
ports:
- "5432:5432"
volumes:
- ./data/pgadmin/
networks:
- pg-network
pgadmin:
image: dpage/pgadmin4
environment:
PGADMIN_DEFAULT_EMAIL: "monnerat#monnerat.com.br"
PGADMIN_DEFAULT_PASSWORD: "abc"
ports:
- "5050:80"
depends_on:
- db
networks:
- pg-network
networks:
pg-network:
driver: bridge
My actual result is connection refused is server running on host "localhost (127.0.0.1) and accepting"
but i expect he open the pgadmin to create the database
Your docker-compose.yml is good. Please see the attached host name should be 'db'

client, err := mongo.NewClient(options.Client().ApplyURI(fmt.Sprintf("mongodb://%s:%s#%s:%d/admin", ROOTUSER, ROOTPASSWORD, HOST, PORT)))
I have thee above docker file and go api which should connect to mongodb.
But my go code gives error "server selection timeout\ncurrent topology: Type: Unknown\nServers:\nAddr: apiwithkubernetesmongodb:27018, Type: Unknown, State: Connected, Average RTT: 0, Last error: connection(apiwithkubernetesmongodb:27018[-249]) connection is closed"
Note: For those who stumble to this, it was all about casing of the name of the service, after switching to all lower case naming, it starts working.
