Simple Website creation using kubernetes and docker

To access the app, visit http://34.69.43.90/ followed by argument. In this case, it will be something like "factorial?number=" followed by a number

Reference example http://34.69.43.90/factorial?number=8

while trying to copy this project, make sure to edit the deployment.yaml file, your docker build and push command should change accordingly.

Sample Build process (Using Google Cloud):

1. setup billing and enable API

   • Kubernetes Engine API
   • Container Registry API
   • Artifact Registry API

2. Open cloud shell

3. add files, either via upload, or create using your favourite editor (mine is nano)

4. Create Docker image

   • command for creating docker image
     • docker build -t gcr.io/GCP_PROJECT_ID/factorial-app .
     • docker push gcr.io/GCP_PROJECT_ID/factorial-app
   • Change the repository location! use that to edit the deployment file too.

5. Create Kubernetes Cluster

   • command for creating cluster
     • gcloud container clusters create factorial-cluster --zone us-central1-c --num-nodes=3
     • gcloud container clusters get-credentials factorial-cluster --zone us-central1-c
   • Change according to your needs

6. apply the deployment and service files using these commands

   • kubectl apply -f deployment.yaml
   • kubectl apply -f service.yaml

7. Verify using these commands

   • kubectl get nodes
   • kubectl get services

8. After you get the external ip address of the load-balancer, access your project using

   • EXTERNAL_IP_ADDRESS/factorial?number=8
   • change number and check if it works

Note: Does not contain any fancy front-end, you are free to add it.
