Mengautomasi workflow Terraform menggunakan CI/CD pipeline — dari plan otomatis hingga policy enforcement dan drift detection.

Apa yang Akan Dipelajari? #

CI/CD pipeline memastikan setiap perubahan infrastruktur melalui proses review, testing, dan approval yang konsisten. Section ini membahas berbagai aspek automasi Terraform termasuk pipeline design, approval workflow, policy as code, dan Terraform Cloud.
