This repository contains an example of how to use Jsonnet and tf.libsonnet to manage a multi-state Terraform project.
This represents a toy example of an AWS stack containing a VPC and MySQL database, that uses a fictional Terraform module to deploy each.
NOTE
The underlying module calls use
null_resources to simulate the resources. However, the general pattern should be extensible to real world modules and use cases.
Refer to Comparison to Terraform HCL for the motivating example and a full walkthrough.
You can generate the Terraform code by using the base Jsonnet tool. To start, install jsonnet and jsonnet-bundler
(aka jb):
Once you have jsonnet and jb installed, generate the code with the following commands:
$ jb install
$ jsonnet -J ./vendor -c -m out/ main.jsonnet
This will output all the Terraform code to the out directory, resulting in the following folder structure:
./out
├── prod
│ ├── mysql
│ │ └── main.tf.json
│ └── vpc
│ └── main.tf.json
└── stage
├── mysql
│ └── main.tf.json
└── vpc
└── main.tf.json
If you have any questions about how to use the tf.libsonnet libraries, ask in the Organization GitHub
