I'm trying to run docker container with django + postgres.
When i run two containers (db + web) i see that it's ok on the db side:
LOG: starting PostgreSQL 12.0 on x86_64-pc-linux-musl, compiled by gcc (Alpine 8.3.0) 8.3.0, 64-bit
LOG: listening on IPv4 address "0.0.0.0", port 5432
LOG: listening on IPv6 address "::", port 5432
LOG: listening on Unix socket "/var/run/postgresql/.s.PGSQL.5432"
LOG: database system was shut down at 2023-02-13 14:36:17 UTC
LOG: database system is ready to accept connections
But on the django side i see the error:
django.db.utils.OperationalError: connection to server at "127.0.0.1", port 5432 failed: Connection refused
Is the server running on that host and accepting TCP/IP connections?
DockerFile:
FROM python:3.10.0-alpine
WORKDIR /usr/src/app
ENV PYTHONDONTWRITEBYTECODE 1
ENV PYTHONUNBUFFERED 1
RUN pip install --upgrade pip
RUN apk update
RUN apk add postgresql-dev gcc python3-dev musl-dev
COPY ./requirements.txt .
RUN pip install -r requirements.txt
COPY . .
docker-compose.yml:
version: '3.9'
services:
web:
build: .
command: python manage.py runserver 0.0.0.0:8000
volumes:
- .:/usr/src/app/
ports:
- 8000:8000
env_file:
- ./.env.dev
depends_on:
- db
db:
image: postgres:12.0-alpine
volumes:
- postgres_data:/var/lib/postgresql/data/
environment:
- POSTGRES_USER=my_admin
- POSTGRES_PASSWORD=my_api
- POSTGRES_DB=my_db
volumes:
postgres_data:
Also, i have this setting in Django:
ALLOWED_HOSTS = ['127.0.0.1', 'localhost', '0.0.0.0', '::1']
And my .env file:
POSTGRES_DB=my_db
POSTGRES_USER=my_admin
POSTGRES_PASSWORD=my_api
POSTGRES_HOST=127.0.0.1
POSTGRES_PORT=5432
What i am doing wrong?
