Django unable to connect to PostgreSQL Docker container using hostname (WSL)

I'm facing an issue where my Django application, running on Windows Subsystem for Linux (WSL), can't connect to a PostgreSQL database running in a Docker container.

The error I'm getting in Django is:

django.db.utils.OperationalError: could not translate host name "postgres" to address: Name or service not known

I'm starting the PostgreSQL container using the following Docker command:

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

And this is my environment varaible in django:

DATABASE_URL=postgres://postgres:postgres@postgres:5432/postgres

How can I fix this?

Solution

  • Just change URL (write localhost:5432):

    DATABASE_URL=postgres://postgres:postgres@localhost:5432/postgres
