Command: validate

The terraform validate command is used to validate the syntax of the terraform files. Terraform performs a syntax check on all the terraform files in the directory, and will display an error if any of the files doesn't validate.

This command does not check formatting (e.g. tabs vs spaces, newlines, comments etc.).

The following can be reported:

• invalid HCL syntax (e.g. missing trailing quote or equal sign)
• invalid HCL references (e.g. variable name or attribute which doesn't exist)
• same provider declared multiple times
• same module declared multiple times
• same resource declared multiple times
• invalid module name
• interpolation used in places where it's unsupported (e.g. variable, depends_on, module.source, provider)

Usage

Usage: terraform validate [dir]

By default, validate requires no flags and looks in the current directory for the configurations.
