I have this line of code:
const client = await MongoClient.connect('mongodb://127.0.0.1:27017')
But I cant run http://localhost:3000 because the code is waiting the connection to the database to start listen to the 3000 port
I need to create a connection to the mongodb from localhost using docker, but dont know how

I have created a PostgreSQL with a web server DOCKER CONTAINER and my app running with an API to manage all the endpoints.
The link of my git repo is: https://github.com/JulioValderrama/store-front-project.git
But I am facing problems with the connections with the Database, as depending on the Postgres HOST name value in my .env file one of the two servers (one local running in PORT 4000 and the web server running in the docker container in PORT 3000) will work or will fail.
I have tried the next:
Local server running in PORT 4000
Docker web server running in PORT 3000
HOST "127.0.0.1"
Going to¨:
http://localhost:3000/
Works fine and get response, now when trying to connect it to any of my database API:
http://localhost:3000/products
I get the error:
"Could not get PRODUCTS. Error: Error: connect ECONNREFUSED 127.0.0.1:5432"
Going to:
http://localhost:4000
Works fine and get response, now when trying to connect it to any of my database API:
http://localhost:4000/products
It works! I get the list of all my products!!
HOST "postgres"
I put "postgres" because I read online that you have to name HOST as the postgres docker image created, which is my case. And it works for the remote server.
Going to:
http://localhost:3000
Works fine and get response, then when trying to connect it to database API:
http://localhost:3000/products
It works!! It gives me the list of my products !!
Going to:
http://localhost:4000
Works fine and get response, then when trying to connect it to database API:
http://localhost:4000/products
It gives me the error:
"Could not get PRODUCTS. Error: Error: getaddrinfo ENOTFOUND postgres"
So it seems like there is an error when trying to connect to the database due to the server or the HOST name, I have no idea....
In docker-compose.yaml you have linked your machine 5432 to containers 5432 port.
If you are using docker container and want to reach postgres, use postgres as POSTGRES_HOST value.
If you are running application outside the docker environment use 0.0.0.0, 127.0.0.1.
Make sure you haven't installed postgres locally
brew uninstall postgres
I have back-end created in nodejs hosted on Debian server using postgres 14.
the Nodejs listenning on port 5000, and when I try to connect to postgres using port 5432, I am getting the following reponse from Postman:
"Password is invalid".
I was trying the postgres role, and to create a new role, and problem is the same.
I was installing postgres on my Windows 10 computer, and all works fine in my localhost, but on the remote server not.
My Nodejs back-end, and postgres are on the same computer, but each role I've tryed won't connect to the database.
There is pg_hba.conf in /etc/postgres/14 on your server you have to add:
host username database 0.0.0.0/0 md5
This would allow connection to database from any host to username using password authentication.
Also there is a pg.conf or postgres conf
There is line allow_connections the value should be '*'
allow_connections='*'
This would generally allow connections to postgres running on that server

don’t forget you have to reload postgres after config change:
systemctl reload postgres
I am trying to connect to my local postgres database from PGadmin in container, but it is through following error:
Unable to connect to Server: connection to server at "localhost" (127.0.0.1), port 5432 failed. connection refused is the server running on that host and accepting TCP/IP connections?
configurations i am trying for creating server are as follows:
hostname/address = localhost
port = 5432
username = postgres
my OS configurations
OS = Linux- Ubuntu
Version = 18.04
PS: there are some existing questions regarding this on Stackoverflow, but no solution helped me.
While it runs locally, the docker container is like a different machine. You need to put the IP address of the local host machine instead of localhost.
I created a database on a remote server. I created a js file to connect to the database using mongoose, express, body-parser.
I made a connection to the remote server with the following command:
mongoose.connect ("mongodb: //176.31.212.51: 27017 / db")
I test the connection and I have a successful connection,
I launched a "listener" to listen on the port as follows:
app.listen (process.env.PORT)
with the port = 3000
I tested and I got an error.
Is there any solution to make a successful connection with the ionic application to do the operations of CRUD?
My app is using websocket with Socket.io library. On the fronted, I open a connection to a backend socket like this :
io.connect(window.location.origin)
Everything is working fine when my backend is running on my computer. But when I run it inside a docker container, I get this error on my client:
WebSocket connection to 'ws://localhost/socket.io/?EIO=3&transport=websocket' failed: Invalid frame header
Figured out that I must make the socket listen on '0.0.0.0'
