docker django部署
https://hub.docker.com/_/django/
（一）dockerfile方法
FROM python:3.4
RUN apt-get update \
&& apt-get install -y --no-install-recommends \
postgresql-client \
&& rm -rf /var/lib/apt/lists/*
WORKDIR /usr/src/app
COPY requirements.txt ./
RUN pip install -r requirements.txt
COPY . .
EXPOSE 8000
CMD ["python", "manage.py", "runserver", "0.0.0.0:8000"]（二）不用dockerfile方法：
$ docker run --name some-django-app -v "$PWD":/usr/src/app -w /usr/src/app -p 8000:8000 \
-d django bash -c "pip install -r requirements.txt && python manage.py runserver 0.0.0.0:8000"
在项目的根目录下执行以上命令即可
[root@centos4 mysite]# ls
blog db.sqlite3 manage.py mysite requirements.txt sftp-config.json static uwsgibk uwsgi.ini
[root@centos4 mysite]#
[root@centos4 mysite]# docker exec -it 236 /bin/bash
root@2361f1355d70:/usr/src/app# ls
blog db.sqlite3 manage.py mysite requirements.txt sftp-config.json static uwsgi.ini uwsgibk
root@2361f1355d70:/usr/src/app#
-v "$PWD":/usr/src/app可以看到宿主机中项目上下能内容已经挂载到容器内的/usr/src/app中了
pip install -r requirements.txtroot@2361f1355d70:/usr/src/app# pip list
DEPRECATION: The default format will switch to columns in the future. You can use --format=(legacy|columns) (or define a format=(legacy|columns) in your pip.conf under the [list] section) to disable this warning.
