This project signifies the successful culmination of the Cloud DevOps Engineer Nanodegree at Udacity through the final Capstone project.

Throughout the Cloud DevOps Nanodegree program, I acquired and applied various skills and knowledge, including:

• Implementing Continuous Integration and Continuous Deployment (CI/CD) using CircleCI
• Building and managing pipelines
• Deploying clusters using Ansible and CloudFormation
• Creating Kubernetes clusters
• Building Docker containers within pipelines
• Working with AWS cloud services

The application is a python3 script that utilizes the Flask framework to render a simple webpage in the user's browser. It includes a requirements.txt file to ensure all necessary dependencies are included.

To deploy the Kubernetes cluster, I leveraged AWS CloudFormation. The CloudFormation deployment process can be divided into four parts:

• Networking, Establishing communication channels for new nodes within the cluster.
• Elastic Kubernetes Service (EKS) Creating the Kubernetes cluster itself.
• NodeGroup, Defining rules for the creation and operation of instances within the EKS cluster.
• Management Configuring and managing the cluster and its deployments and services.

To enable Continuous Integration and Continuous Deployment (CI/CD), I utilized CircleCI to create a pipeline that facilitates manual testing and deployment before automatically deploying changes to the cluster using Ansible.

Code linting is employed to verify the syntactical correctness of the application and Dockerfile, ensuring consistent code quality.

Once the EKS cluster is successfully configured using Ansible within the CI/CD pipeline, the deployment and service can be verified using the following commands:
