Terraform Basics: Data Source Blocks

Data source blocks are the read-only companion to resource blocks. While resource blocks are used to manage resources, data source blocks are used to retrieve information about resources that already exist and are managed by an external entity.

The format of the data source block is the data keyword, data source type, and name label. Inside the block will be a set of required and optional arguments and nested blocks as defined by the data source type. There are also meta-arguments available to all data sources.

You can reference a data source elsewhere in the configuration with the syntax data dot data source type dot name label, and optionally the data source attribute you want to retrieve.

This is part of the Terraform Basics series, a set of video created to focus on one aspect of Terraform and explain it in detail. While not a replacement for a full course, if there's something in Terraform that doesn't quite click with you, hopefully Terraform Basics will fill in the gaps.

Amazing. You are really good at Terraform. Would you mind making some videos with Terraform DEMOs? I mean, using Terraform to create a VPC, a Security Group, a Subnet, an API Gateway, and an EC2 instance or something like that. For example, using Terraform to create an EC2 instance to act as a GitLab runner.
