在Docker上使用Nginx,uWSGI和Postgres配置Django

我正在尝试使用Nginx,uWSGI和Postgres在Docker上设置Django应用程序.我找到了有关为Django和Postgres设置Compose的出色指南：https://docs.docker.com/v1.5/compose/django/

但是,现在我需要添加Nginx和uWSGI.我尝试过在Docker文档的Compose设置中使用此仓库(https://github.com/baxeico/django-uwsgi-nginx)的文件,但遗憾的是没有成功.

这是我输入docker-compose run web时发生的情况：

    or with the pg_config option in 'setup.cfg'.

Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-XRgbSA/psycopg2

这是我的Dockerfile：

from ubuntu:precise

run echo "deb http://us.archive.ubuntu.com/ubuntu/ precise-updates main restricted" | tee -a /etc/apt/sources.list.d/precise-updates.list

# update packages
run apt-get update

# install required packages
run apt-get install -y python python-dev python-setuptools python-software-properties
run apt-get install -y sqlite3
run apt-get install -y supervisor

# add nginx stable ppa
run add-apt-repository -y ppa:nginx/stable
# update packages after adding nginx repository
run apt-get update
# install latest stable nginx
run apt-get install -y nginx

# install pip
run easy_install pip

# install uwsgi now because it takes a little while
run pip install uwsgi

# install our code
add . /home/docker/code/

# setup all the configfiles
run echo "daemon off;" >> /etc/nginx/nginx.conf
run rm /etc/nginx/sites-enabled/default
run ln -s /home/docker/code/nginx-app.conf /etc/nginx/sites-enabled/
run ln -s /home/docker/code/supervisor-app.conf /etc/supervisor/conf.d/

# run pip install
run pip install -r /home/docker/code/app/requirements.txt

run cd /home/docker/code/app && ./manage.py syncdb --noinput

expose 80
cmd ["supervisord","-n"]

和docker-compose.yml：

db:
  image: postgres
web:
  build: .
  command: python vms/manage.py runserver 0.0.0.0:8000
  volumes:
    - .:/code
  ports:
    - "8000:8000"
  links:
    - db

还有名为nginx-app.conf,supervisor-app.conf,uwsgi_params和uwsgi.ini的文件.这些都是来自上述回购. Requirements.txt包含Django 1.9.1,psycopg2和请求.

如果这个科学怪人项目还有更好的选择,我很想听听.

最佳答案

在Ubuntu上,在尝试使用pip安装psycopg2之前,请确保已使用apt-get安装了python-dev和libpq-dev.
