[shikharbhardwaj3110]

Terraform Script:

• Provisioned an AWS ECS cluster of EC2 type.
• Included an Auto Scaling Group for dynamic instance scaling.
• Configured an Application Load Balancer (ALB) for distributing traffic.
• Implemented appropriate networking components:
• Created a Virtual Private Cloud (VPC).
• Defined subnets within the VPC.
• Configured security groups to control inbound and outbound traffic.
• Applied permissions as needed for ECS resources.

YAML Workflow File for CI/CD Pipeline:

• Added a YAML workflow file for the CI/CD pipeline.
• Defined pipeline stages and jobs for building, testing, and deploying infrastructure.
• Integrated with Terraform for infrastructure provisioning.
• Configured triggers for automatic execution on code changes.
• Specified deployment steps for updating the ECS cluster.
• This setup aims to automate the process of building and deploying your AWS ECS infrastructure, ensuring consistency and efficiency in your development workflow.

Steps to run

• Change Github Secrets appropriately by comparing with main.yml file
• Simply add terraform apply -auto-approve in workflow file main.yml in step name: Provision underlying infrastructure for ECS Cluster to provision the infrastructure for app image for the application.

Note

• The certificate.pfx was flagged as expired by AWS ACM, forcing me to change container port to 80 as well as load balancer listener port to 80.
• The tasks for application are no running as expected in ECS Cluster Services, hence resulting in 503 Service Temporarily Unavailable ERROR
