docker-nginx-uwsgi-django

A. environments

• python 3.x
• django 1.11.x

B. create project environments

$ mkdir -p myproject/nginx myproject/django
$ cd myproject/django
$ django-admin startproject myproject

$ cd myproject
$ python3 manage.py runserver 0.0.0.0:8000

C. set docker+uwsgi standalone environments

1. edit files which already exist

1-1. django/myproject/myproject/settings.py

STATIC_ROOT = os.path.abspath(os.path.join(BASE_DIR, '../static'))

2. create files

2-1. django/uwsgi.ini

[uwsgi]
chdir        = /ghilbut/myproject
plugins      = python3
module       = myproject.wsgi:application
env          = DJANGO_SETTINGS_MODULE=myproject.settings

master       = true
processes    = 1
threads      = 4
http-socket  = 0.0.0.0:8000

vaccum       = true
pidfile      = /ghilbut/uwsgi/uwsgi.pid

enable-threads = true
single-interpreter = true
lazy-apps = true

2-2. django/requirements.txt

Django==1.11.7
mysqlclient==1.3.12

2-3. django/.dockerignore

**/__pycache__
**/db.sqlite3
**/*.pyc
**/.*.swp

2-4. django/Dockerfile

RUN python3 manage.py collectstatic

VOLUME ["/ghilbut/static", "/ghilbut/uwsgi"]

ENTRYPOINT [ "/usr/bin/uwsgi", "--ini", "/ghilbut/uwsgi.ini" ]

3. build image and run container

$ docker build -t myproject:0.1 .
$ docker run -it --rm --name myproject -p 8000:8000 myproject:0.1

D. create docker+uwsgi and nginx environments

1. edit files

1-1. django/uwsgi.ini

WORKDIR /ghilbut/myproject
RUN python3 manage.py collectstatic

ENTRYPOINT [ "/usr/bin/uwsgi", "--ini", "/ghilbut/uwsgi.ini" ]

2. create files

2-1. nginx/uwsgi_params

3. build images and run containers

3-1. rebuild and run django+uwsgi

$ docker build -t myproject:0.1 .
$ docker run -it --rm --name myproject myproject:0.1

3-2. build and run nginx

$ docker build -t myproject-nginx:0.1 .
$ docker run -it --rm --name myproject-nginx -p 8000:8000 --volumes-from myproject myproject-nginx:0.1
