Architecture Design

As a DevOps engineer, I want to design the bank app deployment infrastructure so that our application can be built, tested, and deployed automatically and consistently.

EPIC 1 - Preliminary Installations and Setup

• As a devops engineer, I want to purchase and register a domain so I can use it for DNS Management.
• As a devops engineer, I want to install the required tools on my computer so I can work locally on infrastructure code.
  • Task: Install VS Code
  • Task: Install Git
  • Task: Install Terraform
  • Task: Install Docker and Docker Compose
  • Task: Run and verify:
• As a devops engineer, I want to create individual IAM user accounts for my team members so they can securely access AWS resources with appropriate permissions.

EPIC 2 - Building Infrastructure

• As a devops Engineer, I want to replicate the Infrastructure code shared by Engr Smart so that I can use it to provision my AWS Infrastructure.
  • Push Infrastructure code to Public Repo
  • Share the Repo link to the Mayor and Damilola to review
  • Document your steps on a Notion document and share in the comment
• As a devops engineer, I want to review the infrastructure code created by my team to ensure it aligns with what was shared by Engineer Smart
  • List out the list of files and folders to check for during review
  • Clone repository to Local and Review
  • Confirm that the code is complete and inform the team
• As an engineer, I want to deploy modular infrastructure using Terraform for each component.
  • Deploy VPC Module
  • Deploy the EKS Module
  • Configure DNS -
  • Deploy RDS -

EPIC 3 - GitHub Runner Setup

• As a devops engineer, I want to create an EC2 instance so I can run the GitHub self-hosted runner.
  • Launch EC2 instance (Ubuntu 22.04, t2.medium, 20 GB, name: github-runner) -
  • Create and download key pair (.pem file) Kachi
• As a devops engineer, I want to connect to an EC2 instance and configure the environment to run a self-hosted GitHub runner.
  • Configure ~/.ssh/config locally - Ifeoma
  • Connect via Remote-SSH in VS Code and run setup commands
• As a DevOps engineer, I want to containerize and run the GitHub runner on EC2 so my workflows can execute.
  • Create directory get-runner -
  • Add files to the get-runner directory - .env, docker-compose.yml, Dockerfile, entrypoint.sh -
  • Run docker Runner -
  • Check that there are no permission issues.

EPIC 4 - CI/CD Pipeline Setup and Infrastructure Deployment

• As an AWS Admin, I want to create AWS credentials so that GitHub Actions can deploy infrastructure.
  • Description - Create an IAM user named terraform-github
• As a DevOps engineer, I want to store AWS credentials in GitHub so the gitrunner can authenticate to AWS. -
• As a DevOps engineer, I want to configure the CI/CD workflow so infrastructure can be deployed automatically.
• As a devops engineer, I want to push the code and monitor the pipeline to verify deployment.

EPIC 5 - Verify Infrastructure Deployment

• As a tester, I want to verify that AWS resources were provisioned correctly so I can confirm success.
  • Check AWS VPC console → Subnets, gateways, route tables
  • Task: Check EKS console → Cluster is ACTIVE
  • Task: Check RDS console → DB is AVAILABLE
  • Task: Check Route 53 → Hosted zone and A-records are created
  • Task: Check ECR → Repository is setup

Epic 4: Configure and Deploy with Kubernetes

• As a DevOps engineer, I want to provision a MySQL database in the cloud.
• As a developer, I want to ensure CRUD operations are executed securely on the database.

Epic 6: Deploy with Kubernetes

• As a DevOps engineer, I want to deploy frontend, backend, and database services as separate pods in a Kubernetes cluster.
• As a backend developer, I want to define database credentials and use a connection string to link backend to the database.
