Building Automated Pipelines for Infrastructure Code with Terraform and Packer
summary
Uses Terraform and Packer to build immutable images and provision resources, adds automated CI pipelines that build Packer images, run Terratest-style checks by spinning up and tearing down real infrastructure, SSH-ing to verify docker and kubelet, then run terraform plan/apply. Replaces one monolithic repo with separate function-scoped repos and remote state to control dependencies. Adds a promotion pipeline plus a nightly drift detection job that plans and optionally auto-applies fixes. Example problem: a manual apply unexpectedly wanted 20 adds 7 changes and several destroys, fixed by these pipelines.
