Python Console(4)Deployment and Docker

>pip -V
pip 9.0.1 from /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages (python 2.7)

>pip install gunicorn
>pip install greenlet
>pip install eventlet
>pip install gevent

Configuration file
>cat gunicorn.py.ini
import multiprocessing
bind = "127.0.0.1:8000"
workers = multiprocessing.cpu_count() * 2 + 1
worker_class = 'gevent'

running command
>gunicorn -c gunicorn.py.ini myconsole.wsgi

Deployment on RaspberryPi Ubuntu
>sudo apt-get install python3-picamera
>python -V
Python 2.7.9

>python3 -V
Python 3.4.2

>sudo apt-get install python3-pip

>pip3 -V
pip 1.5.6 from /usr/lib/python3/dist-packages (python 3.4)

>sudo pip3 install django

>sudo pip3 install gunicorn
>sudo pip3 install greenlet
>sudo pip3 install gevent
>sudo pip3 install eventlet

>cat gunicorn.py.ini
import multiprocessing
bind = "0.0.0.0:8000"
workers = multiprocessing.cpu_count() * 2 + 1

>gunicorn -c gunicorn.py.ini myconsole.wsgi

Configure the settings.py to solve the allowed host issue
ALLOWED_HOSTS = ['*']

It is a kind of working, but I get the wrong CSS, I was thinking I do not need care about the /static, but I have to.

Solve the Static Issue
>sudo ln -s /home/carl/work/myconsole /opt/myconsole

myconsole/settings.py
STATIC_URL = '/static/‘
STATIC_ROOT = '/opt/myconsole/static/'
STATICFILES_FINDERS = ( 'django.contrib.staticfiles.finders.AppDirectoriesFinder', 'django.contrib.staticfiles.finders.FileSystemFinder', )

>python3 manage.py collectstatic

Still have issue
Not Found: /static/admin/css/base.css
Not Found: /static/admin/css/dashboard.css

Follow this book in details
https://docs.djangoproject.com/en/1.11/howto/static-files/deployment/

Actually after all the steps bellow, it will copy all he files to STATIC_ROOT under the URL STATIC_URL.

add the things to the urls.py
from django.contrib.staticfiles.urls import staticfiles_urlpatterns
urlpatterns += staticfiles_urlpatterns()

It works well.

And I also tried to docker that application on my raspberrypi machine. in sillycat-docker
Makefile
IMAGE=sillycat/public
TAG=raspberrypi-django
NAME=raspberrypi-django

app-build:
rm -fr install/*
wget --no-check-certificate https://github.com/luohuazju/myconsole/archive/master.tar.gz -P install/

docker-context:

build: docker-context
docker build -t $(IMAGE):$(TAG) .

run:
docker run -d -p 8000:8000 --name $(NAME) $(IMAGE):$(TAG)

debug:
docker run -ti -p 8000:8000 --name $(NAME) $(IMAGE):$(TAG) /bin/bash

clean:
docker stop ${NAME}
docker rm ${NAME}

logs:
docker logs ${NAME}

publish:
docker push ${IMAGE}:${TAG}

fetch:
docker pull ${IMAGE}:${TAG}
