Bricks Manifest File Format (bricks.json)

bricks.json is a metadata file used in Atomic Infrastructure™ orchestration.

Every blueprint must have a bricks.json file in its root directory that lists important information about the structure and behavior of that blueprint.

This page explains the structure of the blueprint manifest and the features they can include.

Examples

The following example manifests show the basic manifest structure and some commonly used features as a starting point for creating your own manifest:

Blueprint

{
  "name": "lonely_yellow_beaver",
  "description": "Generated using bricks tf-rescue",
  "version": "1.0.0",
  "state": "managed",
  "props": {
    "bucket_name": {
      "description": "Fallback name for the bucket",
      "type": "string"
    }
  },
  "packages": [
    {
      "name": "aws_sqs_queue",
      "version": "1.0.1",
      "props": {}
    },
    {
      "name": "aws_simple_s3",
      "version": "0.1.1",
      "props": {
        "bucket_name": "Data.aws_sqs_queue.arn ?? Props.bucket_name"
      }
    }
  ]
}

Artifact

Blueprint Vs. Artifact

The native block refers to IaC files archived together with the bricks.json file. It indicates to the orchestrator that besides building relationships, there are files that have to be executed.

A common practice is to create a set of native blueprints and wrap them with a non-native blueprint to orchestrate them all.

On runtime, each native blueprint is planned and applied separately, maintaining a small blast radius and spending up the runtime.
