Deploy an over the top complicated - 4 containers + 1 Relational Database + 1 in-memory Cache - Fibonacci calculator into a staging environment in a public cloud automatically whenever new commits are integrated into the main branch.

Stack:

• Cloud Platform: AWS
• Code Hosting Platform: GitHub
• CI/CD Tool: GitHub Actions
• Infrastructure Management Tool: Terraform
• Container Build Tool: Docker
• Staging Environment: AWS Elastic Beanstalk + RDS + ElastiCache Redis

Overview:

Deployment Local VS Cloud:

Pipeline:

• S3 bucket with versioning to store the Terraform states (see "bucket" in the prebuild configuration and in the deploy staging configuration).
• IAM user named devops_githubactions (see "profile" in the prebuild configuration and in the deploy staging configuration). Programmatic access only with permissions: RDS, IAM, ElastiCache, EC2 Container Registry, S3, VPC, and Elastic Beanstalk.
• Create 4 repository secrets in your GitHub repository: AWS_ACCESS_KEY + AWS_SECRET_KEY of the IAM user newly created, AWS_ACCOUNT_ID, and POSTGRES_PASSWORD with the desired password for the database.
