Terraform must first be installed on your machine. Terraform is distributed as a binary package for all supported platforms and architectures. This page will not cover how to compile Terraform from source, but compiling from source is covered in the documentation for those who want to be sure they're compiling source they trust into the final binary.
To install Terraform, find the appropriate package for your system and download it. Terraform is packaged as a zip archive.
After downloading Terraform, unzip the package. Terraform runs as a single
terraform. Any other files in the package can be safely removed
and Terraform will still function.
The final step is to make sure that the
terraform binary is available on the

Verifying the Installation
After installing Terraform, verify the installation worked by opening a new
terminal session and checking that
terraform is available. By executing
terraform you should see help output similar to this:
$ terraform Usage: terraform [--version] [--help] <command> [args] The available commands for execution are listed below. The most common, useful commands are shown first, followed by less common or more advanced commands. If you're just getting started with Terraform, stick with the common commands. For the other commands, please read the help and docs before usage. Common commands: apply Builds or changes infrastructure console Interactive console for Terraform interpolations # ...
If you get an error that
terraform could not be found, your
variable was not set up properly. Please go back and ensure that your
variable contains the directory where Terraform was installed.
The Terraform CLI has a built-help function. If at any point during this guide you are unsure of how to proceed, consider using the
-help flag with any command. For example:
terraform -help Usage: terraform [-version] [-help] <command> [args] The available commands for execution are listed below. The most common, useful commands are shown first, followed by less common or more advanced commands. If you are just getting started with Terraform, stick with the common commands. For the other commands, please read the help and docs before usage. Common commands: apply Builds or changes infrastructure console Interactive console for Terraform interpolations destroy Destroy Terraform-managed infrastructure env Workspace management fmt Rewrites config files to canonical format get Download and install modules for the configuration graph Create a visual graph of Terraform resources import Import existing infrastructure into Terraform init Initialize a Terraform working directory output Read an output from a state file plan Generate and show an execution plan providers Prints a tree of the providers used in the configuration refresh Update local state file against real resources show Inspect Terraform state or plan taint Manually mark a resource for recreation untaint Manually unmark a resource as tainted validate Validates the Terraform files version Prints the Terraform version workspace Workspace management All other commands: 0.12upgrade Rewrites pre-0.12 module source code for v0.12 debug Debug output management (experimental) force-unlock Manually unlock the terraform state push Obsolete command for Terraform Enterprise legacy (v1) state Advanced state management
Any of these commands can be added to the
--help flag to get more information. For example:
terraform --help plan Usage: terraform plan [options] [DIR] Generates an execution plan for Terraform. This execution plan can be reviewed prior to running apply to get a sense for what Terraform will do. Optionally, the plan can be saved to a Terraform plan file, and apply can take this plan file to execute this plan exactly. Options: -destroy If set, a plan will be generated to destroy all resources managed by the given configuration and state. -detailed-exitcode Return detailed exit codes when the command exits. This will change the meaning of exit codes to: 0 - Succeeded, diff is empty (no changes) 1 - Errored 2 - Succeeded, there is a diff -input=true Ask for input for variables if not directly set. -lock=true Lock the state file when locking is supported. -lock-timeout=0s Duration to retry a state lock. -no-color If specified, output will not contain any color. -out=path Write a plan file to the given path. This can be used as input to the "apply" command. -parallelism=n Limit the number of concurrent operations. Defaults to 10. -refresh=true Update state prior to checking for differences. -state=statefile Path to a Terraform state file to use to look up Terraform-managed resources. By default it will use the state "terraform.tfstate" if it exists. -target=resource Resource to target. Operation will be limited to this resource and its dependencies. This flag can be used multiple times. -var "foo=bar" Set a variable in the Terraform configuration. This flag can be set multiple times. -var-file=foo Set variables in the Terraform configuration from a file. If "terraform.tfvars" or any ".auto.tfvars" files are present, they will be automatically loaded.
