How to deploy as show in diagram?

Create a sibling to the django project directory for saving dockdj settings files which will be used to deploy the django app

$ mkdir deploy

parent
    - hello_world
    |    -hello_world
    |        -wsgi.py
    - deploy

$ cd deploy

$ dockdj init

This will create two files dockdj.yaml and settings.py

parent
    - hello_world
    |    -hello_world
    |        -wsgi.py
    - deploy
        - dockdj.yaml
        - settings.py

Modify the dockdj.yaml file to enter server configuration and app details. Initial file looks as follows. Remove the optional/unused configuration according to your needs.

---
server:
  host: 1.2.3.4
  # must be sudo without password
  username: root
  pem: "/home/user/.ssh/id_rsa"
app:
  # Project name used by script to name docker
  name: hello_world_stage
  settings: 'hello_world/settings.py'
  wsgi:
    app: 'hello_world.wsgi:application'
  asgi: # optional if app uses agsi like channels
    app: 'hello_world.asgi:application'
    paths: # used by nginx to route to asig
      - /ws
      - /some_thing_else
  celery: # optional for celery django app
    app: 'hello_world'
  requirements_file: 'requirements.txt'
  extra_files: # Optional: config, certs any other files loaded to /app/extra_files/* in docker container
    - /path/to/abc.txt
  # Django project directory
  path: "/path/to/django/code/hello_world"
  docker:
    image: python:3.7

compose:
  services:
    celery:
      depends_on:
        - rabbitmq
    rabbitmq:
      image: rabbitmq

settings.py fill contains settings which will be appended to your django app's settings.py file. You can enter production related settings or override development settings here. Initial settings.py file looks like as follows.

DEBUG = False

# Add the your servers host name or ip address
ALLOWED_HOSTS = ['1.2.3.4', 'www.example.com']

CELERY_BROKER_URL = 'amqp://guest:guest@rabbitmq:5672//'

After editing these two files appropriately run following command to setup server. This will install docker in Ubuntu servers if not already installed.

$ dockdj setup

To deploy the django app run following.

$ dockdj deploy

This will create docker images of your Django app. Collects the static file and adds it to nginx container. Runs all required containers as specified in dockdj.yaml. Binds the port 80 of nginx container to port 8000 of Ubuntu host. Port binding can be modified by adding following configuration in `dockdj.yaml'

compose:
  services:
    nginx:
      ports:
      - 8004:80

dockdj stop

Run following command to stop all containers

$ dockdj stop

dockdj restart

Run following command to restart all containers

$ dockdj restart

dockdj logs

Run following command to see logs of all containers

$ dockdj logs

dockdj one-off

You can run one-off script on server using one-off sub command as follows.

$ dockdj one-off python manage.py migrate
