How To Install Terraform In Amazon Linux
To use Terraform you will need to install it. HashiCorp distributes Terraform as a binary package. You can also install Terraform using popular package managers.
»Install Terraform
Retrieve the terraform binary by downloading a pre-compiled binary or compiling it from source.
To install Terraform, find the appropriate package for your system and download it as a zip archive.
After downloading Terraform, unzip the package. Terraform runs as a single binary named terraform. Any other files in the package can be safely removed and Terraform will still function.
Finally, make sure that the terraform binary is available on your PATH. This process will differ depending on your operating system.
Print a colon-separated list of locations in your PATH.
Move the Terraform binary to one of the listed locations. This command assumes that the binary is currently in your downloads folder and that your PATH includes /usr/local/bin, but you can customize it if your locations are different.
$ mv ~/Downloads/terraform /usr/local/bin/ $ mv ~/Downloads/terraform /usr/local/bin/ For more detail about adding binaries to your path, see this Stack Overflow article.
»Verify the installation
Verify that the installation worked by opening a new terminal session and listing Terraform's available subcommands.
$ 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're just getting started with Terraform, stick with the common commands. For the other commands, please read the help and docs before usage. # #...

»Troubleshoot
If you get an error that terraform could not be found, your PATH environment variable was not set up properly. Please go back and ensure that your PATH variable contains the directory where Terraform was installed.
»Enable tab completion
If you use either Bash or Zsh, you can enable tab completion for Terraform commands. To enable autocomplete, first ensure that a config file exists for your chosen shell.
Then install the autocomplete package.
$ terraform -install-autocomplete $ terraform -install-autocomplete Once the autocomplete support is installed, you will need to restart your shell.
»Quick start tutorial
Now that you've installed Terraform, you can provision an NGINX server in less than a minute using Docker on Mac, Windows, or Linux. You can also follow the rest of this tutorial in your web browser.
Click on the tab(s) below relevant to your operating system.
Download Docker Desktop for Mac.
After you install Terraform and Docker on your local machine, start Docker Desktop.
Create a directory named learn-terraform-docker-container.
$ mkdir learn-terraform-docker-container $ mkdir learn-terraform-docker-container Then, navigate into it.
$ cd learn-terraform-docker-container $ cd learn-terraform-docker-container Paste the following Terraform configuration into a file and name it main.tf.
terraform { required_providers { docker = { source = "kreuzwerker/docker" version = "~> 2.13.0" } } } provider "docker" { } resource "docker_image" "nginx" { name = "nginx:latest" keep_locally = false } resource "docker_container" "nginx" { image = docker_image.nginx.latest name = "tutorial" ports { internal = 80 external = 8000 } }
terraform { required_providers { docker = { source = "kreuzwerker/docker" version = "~> 2.13.0" } } } provider "docker" { } resource "docker_image" "nginx" { name = "nginx:latest" keep_locally = false } resource "docker_container" "nginx" { image = docker_image.nginx.latest name = "tutorial" ports { internal = 80 external = 8000 } } Initialize the project, which downloads a plugin that allows Terraform to interact with Docker.
Provision the NGINX server container with apply. When Terraform asks you to confirm type yes and press ENTER.
Verify the existence of the NGINX container by visiting localhost:8000 in your web browser or running docker ps to see the container.
$ docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 425d5ee58619 e791337790a6 "nginx -g 'daemon of…" 20 seconds ago Up 19 seconds 0.0.0.0:8000->80/tcp tutorial
$ docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 425d5ee58619 e791337790a6 "nginx -g 'daemon of…" 20 seconds ago Up 19 seconds 0.0.0.0:8000->80/tcp tutorial To stop the container, run terraform destroy.
You've now provisioned and destroyed an NGINX webserver with Terraform.
