Arc (Area Riservata Cittadino) project infrastructure

Requirements

1. terraform

In order to manage the suitable version of terraform it is strongly recommended to install the following tool:

• tfenv: Terraform version manager inspired by rbenv.

Once these tools have been installed, install the terraform version shown in:

• .terraform-version

After installation install terraform:

tfenv install

Environment management

In order to properly populate terraform variables for each environment, a script located at scripts/terraform.sh is provided.

Terraform invocations described here where environent parameters are required can be replaced with invocations to terraform.sh by passing an environment specification. For example:

./terraform.sh plan itn-dev

NOTE: terraform.sh must be run from the project folder.

Terraform modules

As PagoPA we build our standard Terraform modules, check available modules:

• PagoPA Terraform modules

Terraform lock.hcl

We have both developers who work with your Terraform configuration on their Linux, macOS or Windows workstations and automated systems that apply the configuration while running on Linux. https://www.terraform.io/docs/cli/commands/providers/lock.html#specifying-target-platforms

So we need to specify this in terraform lock providers:

terraform init

terraform providers lock \
  -platform=linux_arm64 \
  -platform=linux_amd64 \
  -platform=darwin_amd64 \
  -platform=windows_amd64
