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.txt

root@2361f1355d70:/usr/src/app# pip list
