使用Docker时遇到问题。要将Django应用程序连接到Postgres数据库,我必须使用:
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql',
'NAME': 'postgres',
'USER': 'postgres',
'HOST': 'db',
'PORT': 5432,
}
}
但是,要在我的Pipenv Shell中通过pytest运行测试,我必须将“主机”从db
更改为localhost
。有什么方法可以随时使用本地主机吗?
Docker-Compose:
version: '3'
services:
db:
image: postgres
ports:
- "5432:5432"
web:
build: .
env_file: .env
volumes:
- .:/code
ports:
- "8000:8000"
depends_on:
- db
container_name: test
Dockerfile:
# Pull base image
FROM python:3
# Set environment varibles
ENV PYTHONUNBUFFERED 1
# Set work directory
RUN mkdir /code
WORKDIR /code
# Install dependencies
RUN pip install --upgrade pip
RUN pip install pipenv
COPY ./Pipfile /code/Pipfile
RUN pipenv install --deploy --system --skip-lock --dev
# Define ENTRYPOINT
COPY ./docker-entrypoint.sh /docker-entrypoint.sh
RUN chmod +x /docker-entrypoint.sh
ENTRYPOINT ["/docker-entrypoint.sh"]
# Copy project
