Kubernetes Django Deployment with Mongo DB

Demo deployment of Mongo DB with Django using K8s

Steps to follow

1. Take a clone of repository

   git clone https://github.com/nishitchittora/kubernetes-django-mongo.git

2. Apply the MongoDB Deployment from the mongo-deployment.yaml file:

   kubectl apply -f ./mongo-deployment.yaml

3. Query the list of Pods to verify that the MongoDB Pod is running:

   kubectl get pods

4. Apply the MongoDB Service from the following mongo-service.yaml file:

   kubectl apply -f ./mongo-service.yaml

5. Query the list of Services to verify that the MongoDB Service is running:

   kubectl get service

6. Apply the backend Deployment from the backend-deployment.yaml file:

   kubectl apply -f ./backend-deployment.yaml

7. Query the list of Pods to verify that the three backend replicas are running:

   kubectl get pods -l app.kubernetes.io/name=django_book -l app.kubernetes.io/component=backend

8. Apply the backend service from the backend-service.yaml file:

   kubectl apply -f ./backend-service.yaml

9. Query the list of services to verify that the backend service is running:

   kubectl get services

10. Then finally, Run the following command to forward port 8080 on your local machine to port 8000 on the service.

    kubectl port-forward svc/backend 8000:8000

Cleaning up

Deleting the Deployments and Services also deletes any running Pods. Use labels to delete multiple resources with one command.

1. Run the following commands to delete all Pods, Deployments, and Services.

   kubectl delete deployment -l app.kubernetes.io/name=mongo
   kubectl delete service -l app.kubernetes.io/name=mongo
   kubectl delete deployment -l app.kubernetes.io/name=django_book
   kubectl delete service -l app.kubernetes.io/name=django_book

2. Query the list of Pods to verify that no Pods are running:

   kubectl get pods
