    How to install or Update Terraform in Linux on AWS

    Terraform is distributed as a binary package for all supported platforms and architectures.
    We need to find out the terraform packages here and download it.  Terraform is packaged as a zip archive.

    Terraform latest version is "1.0.2". If you need to install older version, you can download it from here.


    wget and unzip tool should be installed in your system. If you don’t have then you install them now.

    [root@dockerserver ~]# yum install wget unzip

    I've installed v0.12.12 earlier on my AWS centOS 7 host and i'm updating the terraform version now:

    [root@dockerserver ~]# terraform  version
    Terraform v0.12.12

    Your version of Terraform is out of date! The latest version
    is 0.12.19. You can update by downloading from www.terraform.io/downloads.html
    [root@dockerserver ~]

    Download the newer version:

    [root@dockerserver ~]# wget https://releases.hashicorp.com/terraform/0.12.19/terraform_0.12.19_linux_amd64.zip

    After downloading Terraform, unzip the package. Terraform runs as a single binary named terraform. 

    [root@dockerserver ~]# unzip terraform_0.12.19_linux_amd64.zip
    Archive:  terraform_0.12.19_linux_amd64.zip
    replace terraform? [y]es, [n]o, [A]ll, [N]one, [r]ename: y
      inflating: terraform
    [root@dockerserver ~]#

    Now copy the terraform binary to "/usr/local/bin/"

    [root@dockerserver ~]# cp -pr terraform /usr/local/bin/
    cp: overwrite ‘/usr/local/bin/terraform’? y
    [root@dockerserver ~]#

    Now check the terraform version. Its updated now.

    [root@dockerserver ~]# terraform version
    Terraform v0.12.19
    [root@dockerserver ~]#
