Demo service that provides endpoint to store image/video in the database, create background task using celery to resize/rescale image/video, get the resized image/video.

• Create a psql database and run

  create schema stories_schema;

This will be used by celery as message broker.

• Open a new terminal and run the below commands to start redis-server

  curl -O https://download.redis.io/releases/redis-6.2.1.tar.gz
  tar xzf redis-6.2.1.tar.gz
  rm redis-6.2.1.tar.gz
  cd redis-6.2.1
  make
  src/redis-server

• Open a new terminal and go to the service directory, and run the following -

  virtualenv -p python3.8 venv
  source venv/bin/activate
  pip install -r requirements.txt

• Update the env.sh file with the Postgresql user, password, host, port and database name.
• After updating the env.sh file, run

  bash run_server.sh

The above command will run the server and will also run a celery worker. Now you can hit the endpoints.

• Open a terminal, go to the project directory and run -

docker-compose up (-d)

• You will see that the server_* is crashing, to fix this exec into the db container.

# Open a new terminal, list down all the container
docker ps

# Pick the container with name stories_service_db_1 and run - 
docker exec -it stories_service_db_1 psql -U postgres stories

# Now inside the database run 
create schema stories_schema; 
exit

• Now you will see the server will restart and will be running.
• If the server doesn't restarts, press Ctrl-C and run docker-compose up again.
