Terratag

Terratag is a CLI tool developed by env zero that applies tags or labels across your Infrastructure-as-Code (IaC) codebase. Terratag automatically applies consistent tags to AWS, GCP, and Azure resources across your Terraform or Terragrunt files.

CLI flags

All flags can also be set via environment variables using the pattern TERRATAG_<FLAG_NAME_UPPERCASE> (for example, -tags can be set with TERRATAG_TAGS). Command-line flags take precedence over environment variables.

Flag	Default	Description
`-tags`	(required)	Tags to apply, as a valid JSON object. Example: `'{"env":"prod","team":"platform"}'`
`-dir`	`.`	Directory to recursively search for `.tf` files
`-type`	`terraform`	IaC type. Valid values: `terraform`, `terragrunt`, `terragrunt-run-all`
`-filter`	`.*`	Apply tags only to resource types matching this regex
`-skip`	(none)	Exclude resource types matching this regex from tagging
`-skipTerratagFiles`	`true`	Skip files that were previously tagged by Terratag
`-rename`	`true`	Rename tagged files to `<basename>.terratag.tf`. Set to `false` to edit files in place
`-keep-existing-tags`	`false`	Preserve existing tags when merging. By default, new tags override existing ones
`-default-to-terraform`	`false`	Use Terraform even when OpenTofu is installed
`-verbose`	`false`	Enable verbose logging
`-version`	`false`	Print the version and exit

Terratag is part of the env zero platform ecosystem and integrates with env zero’s Infrastructure-as-Code management capabilities.
