Project Apica-DevOps

Operating System: Ubuntu 22.04.4 LTS

Goals:

1. Create a Docker image for the React application.
2. Deploy the Docker image to the Kubernetes cluster.

Prerequisites:

1. Docker must be installed.
2. MicroK8s is required for running Kubernetes locally.

React Todo List Application

This project uses a simple Todo List application built with React. You can find the source code for the application in the React-Todo-list repository.

Steps:

1. Clone this repository:

   git clone https://github.com/msm17b019/apica-devops.git
   

2. Navigate to the root folder of the repository:

   cd apica-devops
   

3. Run the Docker build command to create a Docker image:

   docker build . -t myapp
   

4. Start the MicroK8s cluster.

5. Load the above docker image to microk8s.

   docker save myapp > myapp.tar
   microk8s ctr image import myapp.tar
   

6. Apply the manifest files from the microk8s directory:

   microk8s kubectl apply -f microk8s/
   

7. Check the NodePort assigned to the todo service. Note the NodePort number listed under the "PORT(S)" column.

   microk8s kubectl get svc todo
   

8. Open your browser and navigate to localhost:NodePort-number. Replace NodePort-number with the actual NodePort number noted from the previous step.

For example, if the NodePort-number is 31402, you would navigate to localhost:31402 in your browser.

This should open up your React Todo List application in the browser.
