The terraform-install script automates the process of downloading and installing Terraform. It provides an ideal method for installing installing updates or a specific version.
This script detects the latest version, OS and CPU-Architecture and allows installation to local or system locations. Optional parameters allow installing a specific version and installing to /usr/local/bin without prompting.
Example - install last pre-0.13 release: ./terraform-install.sh -i 0.12.29
Options:
-i VERSION
: Install specific version-a
: Automatically usesudo
to install to /usr/local/bin- allows for unattended installation via scripts or CD tools
- can be set as default behavior by uncommenting line 14 (
sudoInstall=true
) - sudo password may be required unless NOPASSWD is enabled
-c
: leave binary in working directory (for CI/DevOps use)-h
: help-v
: display version
This installer is similar to my Packer Installer and Vault Installer
