terraform init [1] command is used to initialize a working directory (.terraform/) containing Terraform configuration files: main.tf. Downloads plugins and retrieves teh source code from referenced modules.

During terraform init, the configuration is searched for module blocks, and the source code for referenced modules is retrieved from the locations given in their source arguments.

It is safe to run terraform init multiple times.
