docker run --name postgresDb -e POSTGRES_PASSWORD=sweabhishek -d -p 5432:5432 postgres

Connection String

postgresql://postgres:mysecretpassword@localhost:5432/postgres?sslmode=disable

What the command does

• -name postgresDb → Container name = postgresDb
• e POSTGRES_PASSWORD=sweabhishek → Sets the password for the default postgres user
• p 5432:5432 → Maps port 5432 on your local machine to port 5432 inside the container
• postgres → Uses the official PostgreSQL image

By default, this container creates:

• Username: postgres
• Password: sweabhishek
• Database: postgres
• Port: 5432
• Host (from your local machine): localhost

✅ Connection string formats

psql -h localhost -p 5432 -U postgres -d postgres

Then it’ll ask for your password (sweabhishek).

If you want to pass the password inline (for automation/testing):
