Automating Immutable Infrastructure With Packer & Terraform
summary
Demo shows Terraform Core features (pre and post conditions, move blocks, optional object attributes) driving Terraform Cloud and HCP Packer to produce immutable AMIs and enforce health. A simple web server module creates 9 resources via the private registry and an auto-apply no-code flow; running Spectral flags 17 issues, InfraCost reports ~$10.97/month, and manual AWS edits (removed tag and SSH rule) trigger drift detection and continuous validation that catches a mismatched AMI and failed post-condition.
