Installing Terraform on macOS

We are going to use Homebrew to install Terraform.

First, let's add Hashicorp repo into the registry:

brew tap hashicorp/tap

And install terraform:

brew install hashicorp/tap/terraform

Check that terraform has been installed:

terraform -help

this should return the list of supported Terraform commands.

The installation part is now finished. Optionally, one may decide to install shell autocompletion package for Terraform:

touch ~/.zshrc

this will create shell config file if it does not exist.

Then install Terraform autocomplete:

terraform -install-autocomplete

Now, due to this defect, we have to manually add the following command to shell config:

autoload -Uz compinit && compinit

This line should be added before terraform autocompletion configuration. So edit your .zshrc file so that the last lines are like the following:

autoload -U +X bashcompinit && bashcompinit
autoload -Uz compinit && compinit
complete -o nospace -C /opt/homebrew/bin/terraform terraform
