🐛 Bug Report

Im have this error when i try to run docker compose up --build :
Error: connect ECONNREFUSED 172.18.0.2:55432
at TCPConnectWrap.afterConnect [as oncomplete] (node:net:1555:16)

🤷‍♀️ What did you do

i have used the tool to generate the dockerfile and docker-compose.yaml file .. then i tried to run the app using docker compose up --build , defined hosts for db as localhost and port as 55432

my docker compose file :

version: '3'

## 🙇‍♀️ Expected behavior/code

Show have start the app normally and connect to database 

## 👩‍💻 Environment

- 📦 Node version: 18 (based on the docker compose file)

Default port for poatgres is 5432 not 55432

[AhmedWagdi1]

it worked after changing mapping to default port ,, thank you

but now it is not creating the user as expected . i get

xtechDB       | 2024-02-06 13:55:51.451 UTC [35] FATAL:  password authentication failed for user "xtechdbuser"
xtechDB       | 2024-02-06 13:55:51.451 UTC [35] DETAIL:  Role "xtechdbuser" does not exist.```

Ahmed, Try with the default settings first.

For example:

• example run 1: Use all default settings. Run with docker-compose up (note: the strapi-tools-dockerize project will generate new keys in the .env file everytime it is setup)
• example run 2: Set your own env vars, in the .env file, as shown below. Run with docker-compose up
• example run 3: Maybe for this example, start trying to use the Dockerfile.prod file by specifying it in the docker-compose.yml file, OR, by using docker build on the Dockerfile.prod, then publishing it to a docker container registry, and specifying the published image as the strapi container to use, in the docker-compose.yml file.

You'll need to set these items as env vars, in the .env file. For "someKeyFromRandomKeyGenerator" I recommend using a key generator to generate a random key for those items.

These are all the items you'll need in the .env file. And this assumes you have the project use postgres as the database.
