password authentication failed for user "root", postgresSQL and docker-CodePudding

I'm trying to connect to my database using postgres on docker but it says that the password authentication failed.

My code:

const { Client } = require('pg');

const client = new Client({
  host: 'localhost',
  port: 5432,
  user: 'root',
  password: 'root',
  database: 'mycontacts',
});

client.connect();

docker command to start the postgres container:

docker run --name postg -e POSTGRES_USER=root2 -e POSTGRES_PASSWORD=root2 -p 5432:5432 -d postgres

CodePudding user response：

Try creating another Postgres container to try and connect and it will work. Else. password authentication failed while trying to connect into my docker database

CodePudding user response：

It ended up being the postgres that i had installed on my pc.

I uninstalled it and now its working!
