The Documentation Standard

Release Workflow

The 5-Stage CI/CD Pipeline

01 / SOURCE

Code

Developers push feature branches and initiate Pull Requests with branch protection rules.

02 / VALIDATION

Test & Scan

Automated test suites run alongside SonarQube code quality checks and Trivy image vulnerability scans.

03 / BUILD

Package

Multi-stage Docker images are built and pushed with immutable Git SHA tags to ECR or Google Container Registry.

04 / STAGING

Verify

Coolify provisions isolated preview environments and ephemeral databases for QA sign-off.

05 / PRODUCTION

Deploy

Target-tracking ECS Fargate and Kubernetes clusters perform zero-downtime rolling updates with automatic rollback safety.

The Methodology

Build. Automate. Observe. Improve.

Every deployment should be repeatable. Infrastructure must be defined as version-controlled code, application releases must be automated without manual intervention, and production environments should maintain complete telemetry visibility.

“Automate everything you can. Document everything you cannot.”

By leveraging Terraform modules across AWS and GCP, Docker containers, and unified CI/CD pipelines, we ensure rapid recovery, deterministic environments, and high operational reliability.
