Installing Terraform on Ubuntu 22.04
1) Add Terrafrom APT Repository
Terraform package is not available in default package repositories of Ubuntu 22.04. So, for its installation, we must add hashicorp apt repository.

$ wget -O- https://apt.releases.hashicorp.com/gpg | sudo gpg --dearmor -o /usr/share/keyrings/hashicorp-archive-keyring.gpg $ echo "deb [signed-by=/usr/share/keyrings/hashicorp-archive-keyring.gpg] https://apt.releases.hashicorp.com $(lsb_release -cs) main" | sudo tee /etc/apt/sources.list.d/hashicorp.list
2) Install Terraform using Apt Command
Run beneath apt commands to install terraform,
$ sudo apt update $ sudo apt install terraform -y
Post terraform installation, verify its version,
$ terraform version Terraform v1.5.7 on linux_amd64 $
Test Terraform Installation
To test terraform installation, we will try to execute below terraform example. But before that let’s understand its important files.
- main.tf : It is the main configuration file containing resource definition
- variables.tf : It contains variables declarations.
- outputs.tf : This contains output from the resources.
- provider.tf : It contains provider definition.
Example : Using Local provider, create a file nix.txt.
$ mkdir iac01 && cd iac01
$ vi main.tf
resource "local_file" "distros" {
filename = "/tmp/nix.txt"
content = "I Love Linux distros like Ubuntu. Debian, RHEL, Rocky Linux & Kali Linux etc"
}
Save and close the file
Next initialize the terraform, plan and apply.
$ terraform init
$ terraform plan
$ terraform apply
Verify whether the file has been created or not.
$ ls -l /tmp/nix.txt -rwxrwxr-x 1 linuxbuzz linuxbuzz 76 Sep 18 12:47 /tmp/nix.txt $
To destroy this resource, run
$ terraform destroy
