Steps to run the project

1. Setup docker swarm with manager and worker nodes.

2. create two overlay networks in docker

3. pgcluster_network 2 .traefik-public

4. to deploy the application first we must build a registry,

docker run -d -p 5000:5000 --restart always --name registry registry:2

4. Run the above configuration provided

5. next run docker-compose -f docker-compose-prod.yaml up file to build the image

6. run docker-compose down --volumes to bring it down

7. docker-compose -f docker-compose-prod.yaml push to push the image to the registry

8. run docker stack deploy -c docker -compose-prod django-prod
