Installing Substrate and Terraform

Most steps in the getting started guide only need to be performed once. This step is the exception. Everyone who’s going to be running Substrate commands, writing Terraform code, or really interacting with AWS in any but the most superficial ways, should follow these steps.

Substrate

Substrate is distributed directly to customers. You’ll have access to a feed of releases which includes links to download tarballs. Download the latest one for your platform. Then extract it by running a command like this from your downloads directory:

tar xf substrate-version-commit-GOOS-GOARCH.tar.gz -C ~/bin --strip-components 1

GOOS is one of “darwin” or “linux” and GOARCH is one of “amd64” or “arm64”.

You can install Substrate wherever you like, if ~/bin doesn’t suit you, just ensure that directory is on your PATH.

Terraform

Substrate currently requires exactly Terraform 1.1.6. (Substrate asks for Terraform to be upgraded every few releases to stay nearly current with Terraform.)

You can download Terraform 1.1.6 from Hashicorp, with the filenames being parameterized with GOOS and GOARCH the same as Substrate itself. Download and unzip the appropriate build. Move terraform into a directory on your PATH. (It doesn’t have to be the same directory where you placed substrate.)
