Main commands: init Prepare your working directory for other commands validate Check whether the configuration is valid plan Show changes required by the current configuration apply Create or update infrastructure destroy Destroy previously-created infrastructure All other commands: console Try Terraform expressions at an interactive command prompt fmt Reformat your configuration in the standard style force-unlock Release a stuck lock on the current workspace get Install or upgrade remote Terraform modules graph Generate a Graphviz graph of the steps in an operation import Associate existing infrastructure with a Terraform resource login Obtain and save credentials for a remote host logout Remove locally-stored credentials for a remote host output Show output values from your root module providers Show the providers required for this configuration refresh Update the state to match remote systems show Show the current state or a saved plan state Advanced state management taint Mark a resource instance as not fully functional untaint Remove the 'tainted' state from a resource instance version Show the current Terraform version workspace Workspace management
Global options (use these before the subcommand, if any):
-chdir=DIR Switch to a different working directory before executing the given subcommand. -help Show this help output, or the help for a specified subcommand. -version An alias for the "version" subcommand.
