I have tried to dockerize NestJS app with PostgreSQL. Postgres is refusing connection and is also showing one log that says database system was shut down at <<some timestamp>>. This is docker-compose.yml and the logs.

And I have also tried most of the relevant answers (before Stackoverlow stars marking me as duplicate) and they didn't work. Yes, I have tried changing the host to host.docker.internal as suggested by the previous
For more clarity, here is my typeorm-datasource config in NestJS
import { DataSource } from 'typeorm';
export const typeOrmConnectionDataSource = new DataSource({
type: 'postgres',
host: 'host.docker.internal',
port: 5432,
username: 'postgres',
password: 'postgres',
database: 'gm',
entities: [__dirname + '/**/*.entity{.ts,.js}'],
migrations: [__dirname + '/migrations/**/*{.ts,.js}'],
logging: true,
synchronize: false,
migrationsRun: false,
});
The reason this problem is different is due to the reason because
Apparently the problem lies in NestJS not compiling properly because of my customization to its scripts. Check if that's an issue.
After fixing this issue, Just follow the instructions to use "postgres" as host, and it will work (if you are facing the same issue).
