Projects Setup
SSOServer
A Simple SSO server that handles Authentication and Authorization (JWT)
we need to create our tables in the database, to do that, run the following command:
$ python manage.py migrate
start the development server:
$ python manage.py runserver
finally running the Celery worker server(adding dynamic data to the order items in other services):
$ celery -A admin_tasks worker --loglevel=info
Other Projects
The McDonald and the Uber Project is the same project with different name (for demonstration purposes only):
McDonald
postgres requirement:
user=python_user
password=^uCd*r7-M$
database=mcdonald_db
create the tables with:
$ python manage.py migrate
start the development server(port=8001):
$ python manage.py runserver 8001
finally running the Celery worker server(adding dynamic data to the order items in other services): the celery worker just handles tasks in the mcdonald queue
$ celery -A mcdonald_tasks worker --loglevel=info -Q mcdonald
Uber
postgres requirement:
user=python_user
password=^uCd*r7-M$
database=uber_db
create the tables with:
$ python manage.py migrate
start the development server(port=8002):
$ python manage.py runserver 8002
finally running the Celery worker server(adding dynamic data to the order items in other services): the celery worker just handles tasks in the uber queue
$ celery -A uber_tasks worker --loglevel=info -Q uber
