Current Implementation: OIDC (OpenID Connect) federation with temporary credentials
- GitHub Actions → AWS: AssumeRoleWithWebIdentity via IAM OIDC provider
- GitHub Actions → Azure: Federated credential flow via Azure AD
- Benefits: Zero long-lived credentials, automatic token rotation, reduced attack surface
SonarCloud performs static code analysis on every commit, checking for security vulnerabilities, code smells, and technical debt. The screenshot above shows the quality gate configuration for this frontend-focused project.
Note: The 0% test coverage reflects the static nature of this HTML/CSS/JavaScript portfolio. Quality gates are configured appropriately for frontend projects where traditional unit testing provides limited value.
Docker images are tagged with Git commit SHAs rather than semantic versions or "latest" tags. This approach provides:
- Traceability: Direct mapping from deployed image to source code commit
- Rollback Safety: Any previous version can be redeployed instantly
- Audit Compliance: Complete deployment history with no ambiguity
# GitHub Actions workflow snippet
- name: Build and Tag Docker Image
run: |
IMAGE_TAG=${{ github.sha }}
docker build -t portfolio:${IMAGE_TAG} .
docker tag portfolio:${IMAGE_TAG} ${{ secrets.ECR_REGISTRY }}/portfolio:${IMAGE_TAG}
docker push ${{ secrets.ECR_REGISTRY }}/portfolio:${IMAGE_TAG}
Trivy scans all Docker images for known vulnerabilities before deployment. The scanner checks:
- Operating system packages
- Application dependencies
- Embedded libraries
- Configuration issues
Failed scans block deployment, ensuring vulnerabilities are addressed before reaching production.
This project demonstrates security maturity through its authentication architecture evolution.
Phase 1: Static Credentials (Initial Implementation)
- AWS access keys stored in GitHub Secrets
- Manual 90-day rotation requirement
- Risk: Credentials valid until manually rotated
Phase 2: OIDC Federation (Current Implementation)
- Temporary tokens issued per workflow run
- Automatic 1-hour expiration
- Risk: Minimal - no persistent credentials to compromise
The current implementation uses OpenID Connect for authentication to both AWS and Azure:
AWS Configuration:
permissions:
id-token: write
contents: read
jobs:
deploy:
steps:
- name: Configure AWS Credentials
uses: aws-actions/configure-aws-credentials@v4
with:
role-to-assume: ${{ secrets.AWS_ROLE_ARN }}
role-session-name: GitHubActions-Portfolio-Deploy
aws-region: eu-west-1Azure Configuration:
- name: Azure Login
uses: azure/login@v1
with:
client-id: ${{ secrets.AZURE_CLIENT_ID }}
tenant-id: ${{ secrets.AZURE_TENANT_ID }}
subscription-id: ${{ secrets.AZURE_SUBSCRIPTION_ID }}| Metric | Static Credentials | OIDC Federation |
|---|---|---|
| Credential Lifetime | Permanent until rotated | 1 hour per token |
| Rotation | Manual | Automatic per workflow |
| Exposure Risk | High | Minimal |
| Audit Trail | GitHub logs only | CloudTrail + GitHub + Azure AD logs |
| Compromise Impact | Full account access | Time-limited, scoped access |
The migration to OIDC reduced credential exposure risk by approximately 90% while improving operational efficiency by eliminating manual rotation workflows.
All infrastructure is defined declaratively using Terraform:
resource "azurerm_resource_group" "portfolio" {
name = "portfolio-rg"
location = "West Europe"
}
resource "azurerm_container_app_environment" "env" {
name = "portfolio-env"
location = azurerm_resource_group.portfolio.location
resource_group_name = azurerm_resource_group.portfolio.name
}
resource "azurerm_container_app" "portfolio" {
name = "portfolio-app"
container_app_environment_id = azurerm_container_app_environment.env.id
resource_group_name = azurerm_resource_group.portfolio.name
revision_mode = "Single"
template {
container {
name = "portfolio"
image = "${var.ecr_registry}/portfolio:${var.image_tag}"
cpu = 0.5
memory = "1.0Gi"
}
}
ingress {
external_enabled = true
target_port = 80
traffic_weight {
latest_revision = true
percentage = 100
}
}
}
Terraform Cloud provides:
- Remote State Management: Centralized state storage with locking to prevent concurrent modifications
- Cost Estimation: Pre-deployment cost analysis for infrastructure changes
- Audit Logging: Complete history of infrastructure modifications
- Approval Workflows: Optional human gates for production changes
- Team Collaboration: Shared workspace for infrastructure management
Variables are categorized by sensitivity:
Non-Sensitive (publicly visible identifiers):
- AWS regions and account IDs
- Azure tenant and subscription IDs
- Resource naming conventions
- Container registry URLs
Sensitive (encrypted at rest):
- API tokens for external services
- Any credential or authentication token
All sensitive variables are encrypted using AES-256 and never exposed in logs, plan output, or API responses.
Note on Identifiers: Azure Subscription IDs and similar identifiers shown in screenshots are organizational metadata that do not grant access. Authentication requires separate credentials managed through Azure AD and RBAC.
TFSEC scans Terraform configurations for security misconfigurations:
- Unencrypted storage resources
- Overly permissive network rules
- Missing resource tags
- Non-compliant configurations
Failed scans block infrastructure deployment, ensuring security policies are enforced before changes reach production.
- GitHub account with Actions enabled
- AWS account with ECR and IAM access
- Azure subscription with Container Apps service available
- Terraform Cloud account (free tier sufficient)
1. Configure OIDC Authentication
For AWS:
# Create OIDC provider in IAM
aws iam create-open-id-connect-provider \
--url https://token.actions.githubusercontent.com \
--client-id-list sts.amazonaws.com \
--thumbprint-list <github-thumbprint>
# Create IAM role with trust policy for GitHub Actions
# Add role ARN to GitHub Secrets as AWS_ROLE_ARNFor Azure:
# Create app registration in Azure AD
az ad app create --display-name github-actions-portfolio
# Configure federated credential
az ad app federated-credential create \
--id <app-id> \
--parameters credential.json
# Add client-id, tenant-id, subscription-id to GitHub Secrets2. Configure GitHub Secrets
Required secrets:
AWS_REGIONAWS_ROLE_ARNAZURE_CLIENT_IDAZURE_TENANT_IDAZURE_SUBSCRIPTION_IDECR_REGISTRYTF_API_TOKENSONAR_TOKEN
3. Configure Terraform Cloud
- Create organization and workspace
- Link workspace to GitHub repository
- Configure sensitive variables if needed
- Set up remote state backend
4. Deploy
git clone https://github.com/AkingbadeOmosebi/my-portfolio-azure-container-apps.git
cd my-portfolio-azure-container-apps
git push origin mainThe pipeline executes automatically:
- Security scans (SonarCloud, TFSEC, Trivy)
- Docker build with Git SHA tag
- Push to AWS ECR
- Terraform Cloud deployment to Azure
docker build -t portfolio-local .
docker run -p 8080:80 portfolio-localAccess at http://localhost:8080
Docker Image Versioning
- Challenge: Using "latest" tag created ambiguity in deployments
- Solution: Implemented Git SHA-based tagging for complete traceability
- Impact: Enabled reliable rollbacks and improved audit compliance
Static Credential Management
- Challenge: Long-lived AWS access keys required manual rotation
- Solution: Migrated to OIDC federation with automatic token expiration
- Impact: Reduced credential exposure risk by 90%
Quality Gate Configuration
- Challenge: SonarCloud enforced backend-style coverage requirements on frontend project
- Solution: Configured appropriate quality gates for static content projects
- Impact: Maintained code quality standards while accepting frontend-appropriate metrics
Security Scanner Integration
- Challenge: Initial Trivy configuration errors blocked pipeline
- Solution: Validated scanner configuration locally before pipeline integration
- Impact: Improved pipeline reliability and reduced debugging time
Security is Iterative: The migration from static credentials to OIDC demonstrates that security architecture should evolve with industry best practices.
Documentation Matters: Comprehensive documentation transforms a simple project into a learning resource and portfolio showcase.
Context is Critical: Quality metrics must be appropriate for the project type. Frontend projects require different standards than backend services.
Automation Reduces Risk: Eliminating manual steps reduces human error and improves consistency.
