Stage 10: Scan Docker Image (Trivy)

Description:

Scan Docker image for vulnerabilities and security issues using Trivy.

Steps:

1. Pull Docker image locally.

2. Run Trivy scan on Docker image.

3. Generate report highlighting vulnerabilities found.

Stage 11: Push Docker Image to Docker Hub Repo

Description:

Push the built Docker image to a Docker Hub repository for centralized storage and distribution.

Steps:

1. Authenticate with Docker Hub.

2. Push Docker image to designated repository.

Stage 12: Update Image in Manifests Files

Description:

Update Kubernetes manifests files to reference the newly built Docker image.

Steps:

1. Update deployment YAML files with the latest image tag.

2. Commit changes to version control.

Stage 13: Deploy Application to Kubernetes Cluster

Description:

Deploy the application to a Kubernetes cluster for container orchestration.

Steps:

1. Authenticate with Kubernetes cluster.

2. Apply updated manifests files to deploy new version of the application

Stage 14: Verify Deployment

Description:

Verify successful deployment of the application to the Kubernetes cluster.

Steps:

1. Check deployment status in Kubernetes dashboard or CLI.

2. Perform smoke tests to ensure application functionality.

Stage 15: OWASP ZAP Analysis

Description:

Conduct security testing using OWASP ZAP to identify and mitigate potential security vulnerabilities.

Steps:

1. Configure OWASP ZAP to scan the deployed application.

2. 2. Analyze scan results for security vulnerabilities.

Stage 16: Send Mail Notifications

Description:

Notify stakeholders about pipeline status and results via email.

Steps:

1. Configure email server settings.

2. Send email notifications with pipeline status and relevant reports.

Each stage in the pipeline plays a crucial role in ensuring the reliability, security, and quality of the deployed application. Integrating these stages into a seamless CI/CD pipeline facilitates efficient and automated software delivery.
