9. ⁄ Infrastructure as Code
10. Infrastructure as Code ▪ executable documentation ▪ enables collaboration ▪ safe and predictable

16. ⁄ HashiCorp Configuration Language
17. HashiCorp Configuration Language CODE EDITOR service "http" "web_proxy" { listen_addr = "127.0.0.1:8080" process "server" { command = ["proxy-app", "server"] } } variable "port" { description = "Port for web_proxy" default = 8080 }
18. HashiCorp Configuration Language CODE EDITOR service "http" "web_proxy" { listen_addr = "127.0.0.1:${var.port}" process "server" { command = ["proxy-app", "server"] } } variable "port" { description = "Port for web_proxy" default = 8080 }
19. ⁄ Terraform-native Code Quality Tools
20. Command: terraform fmt TERMINAL > terraform fmt provider.tf terraform.tf
21. Command: terraform validate TERMINAL > terraform validate Success! The configuration is valid.
22. ⁄ TFLint
23. TFLint .tflint.hcl rule "terraform_required_providers" { enabled = true } rule "terraform_required_version" { enabled = true } rule "terraform_naming_convention" { enabled = true format = "snake_case" }
24. Command: tflint TERMINAL > tflint 1 issue(s) found: Warning: data "google_projects" "projects" is declared but not used (terraform_unused_declarations) on data-sources.tf line 11: 11: data "google_projects" "projects" {
25. ⁄ pre-commit
