How to Install Terraform on Fedora

Terraform is an infrastructure-as-code tool that allows you to provision and manage infrastructure in any cloud created by HashiCorp. It provides a rich interface for orchestrating single or multi-cloud deployments. Using Terraform, you can provision all the infrastructure components in code. If you are looking for a tool to manage infrastructure components, such as computing, storage, and networking resources, then Terraform is the best tool.

This post will show you how to install Terraform on Fedora Linux.

Step 1 – Install Terraform from Hashicorp Repo

By default, the Terraform package is unavailable in the Fedora default repo, so you will need to install it from the HashiCorp repo.

First, update the server and install the HashiCorp repo with the following commands.

dnf update -y
dnf install -y dnf-plugins-core
dnf config-manager --add-repo https://rpm.releases.hashicorp.com/fedora/hashicorp.repo

Next, verify the added repo with the following command.

dnf repolist

You will see the following output.

repo id                                                      repo name
fedora                                                       Fedora 34 - x86_64
fedora-cisco-openh264                                        Fedora 34 openh264 (From Cisco) - x86_64
fedora-modular                                               Fedora Modular 34 - x86_64
hashicorp                                                    Hashicorp Stable - x86_64
updates                                                      Fedora 34 - x86_64 - Updates
updates-modular                                              Fedora Modular 34 - x86_64 - Updates

Next, install Terraform using the following command.

dnf install terraform -y

After the installation, verify the Terraform version with the following command.

terraform --version

Output:

Terraform v1.5.7
on linux_amd64

Step 2 – Install Terraform Manually

You can also install Terraform manually by downloading it from GitHub. Run the following command to download the latest version of Terraform.

TER_VER=`curl -s https://api.github.com/repos/hashicorp/terraform/releases/latest | grep tag_name | cut -d: -f2 | tr -d \"\,\v | awk '{$1=$1};1'`
wget https://releases.hashicorp.com/terraform/${TER_VER}/terraform_${TER_VER}_linux_amd64.zip

Once the download is completed, unzip the downloaded file.

unzip terraform_${TER_VER}_linux_amd64.zip

Next, move the Terraform binary to the system location.

mv terraform /usr/bin/

Next, verify the Terraform version using the following command.

terraform --version

You will see the Terraform version in the following output.

Terraform v1.5.7
on linux_amd64

Step 3 – How to Use Terraform

You can see all available options for Terraform using the following command.

terraform

You will see the following output.

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
  metadata      Metadata related commands
  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
  test          Experimental support for module integration testing
  untaint       Remove the 'tainted' state from a resource instance
  version       Show the current Terraform version
  workspace     Workspace management

Now, let’s create a new project and see how to use Terraform to manage infrastructure.

mkdir projects

Next, create a Terraform main configuration file inside the project directory.

cd projects
nano main.tf

Add your cloud provider’s information as shown below.

 provider "aws" {
   access_key = ""
   secret_key = ""
   region = "us-west-1"
 }

Save and close the file, then initialize a Terraform working directory using the following command.

terraform init

You will see the following output.

Initializing the backend...

Initializing provider plugins...
- Finding latest version of hashicorp/aws...
- Installing hashicorp/aws v5.16.2...
- Installed hashicorp/aws v5.16.2 (signed by HashiCorp)

Terraform has created a lock file .terraform.lock.hcl to record the provider
selections it made above. Include this file in your version control repository
so that Terraform can guarantee to make the same selections by default when
you run "terraform init" in the future.

Terraform has been successfully initialized!

You may now begin working with Terraform. Try running "terraform plan" to see
any changes that are required for your infrastructure. All Terraform commands
should now work.

If you ever set or change modules or backend configuration for Terraform,
rerun this command to reinitialize your working directory. If you forget, other
commands will detect it and remind you to do so if necessary.

Next, generate an execution plan using the following command.

terraform plan

Output:

No changes. Your infrastructure matches the configuration.

Terraform has compared your real infrastructure against your configuration and found no differences, so no changes are needed.

Now, run the following command to build your infrastructure.

terraform apply

Output:

No changes. Your infrastructure matches the configuration.

Terraform has compared your real infrastructure against your configuration and found no differences, so no changes are needed.

Apply complete! Resources: 0 added, 0 changed, 0 destroyed.

If you want to destroy your infrastructure, run the following command.

terraform destroy
