Terraform CLI Cheat Sheet


Learn the Learn how Terraform fits into the. Terraform is controlled via a very easy to use command-line interface CLI. Terraform is only a single command-line application: terraform. This application then takes a subcommand such as "apply" or "plan". The complete list of subcommands is in the navigation to the left. The terraform CLI is a well-behaved command line application. In erroneous cases, a non-zero exit status will be returned. It also responds to -h and --help as you'd most likely expect. To get help for any specific command, pass the -h flag to the relevant subcommand. For example, to see help about the graph subcommand:. If you use either bash or zsh as your command shell, Terraform can provide tab-completion support for all command names and at this time some command arguments. After installation, it is necessary to restart your shell or to re-read its profile script before completion will be activated. To uninstall the completion hook, assuming that it has not been modified manually in the shell profile, run the following command:. Currently not all of Terraform's subcommands have full tab-completion support for all arguments. We plan to improve tab-completion coverage over time. The Terraform CLI commands interact with the HashiCorp service Checkpoint to check for the availability of new versions and for critical security bulletins about the current version. One place where the effect of this can be seen is in terraform versionwhere it is used by default to indicate in the output when a newer version is available. Only anonymous information, which cannot be used to identify the user or host, is sent to Checkpoint. An anonymous ID is sent which helps de-duplicate warning messages. Both the anonymous id and the use of checkpoint itself are completely optional and can be disabled. Alternatively, settings in the CLI configuration file can be used to disable checkpoint features. The following checkpoint-related settings are supported in this file:. This allows Terraform to check for security bulletins but does not send the anonymous signature in these requests.
