Quickstart

Requirement

• Docker Desktop
• Visual Studio Code
  • Remote Development Extension Pack

Setup

1. Clone or download this project

git clone https://github.com/yukihiko-shinoda/docker-compose-terraform.git

3. Open Visual Studio Code on root directory

code .

4. Reopen in Container

5. Create config.yml to customize for your Terraform project

Details is explained by comments in its file.

6. Create report.md.jinja to render report of plans

Copy report.md.jinja.dist to report.md.jinja, then edit it.

The differences of all plan is rendered at point of corresponding environment name which is defined into config.yml.

EX:

projects:
  terraform-project-a:
# ------------------------------
    environments:
      dev: {}
      prod: {}

## dev

```console
{{ dev }}
```

## prod

```console
{{ prod }}
```

Usage

Format and test code quickly

fmt-test <project directory name>

EX:

fmt-test terraform-project-a

Plan all environment

Note: If you are using Terraform Enterprise, it requires to login to Terraform Enterprise before run following commands.

pytest tests --prj <project name defined in YAML>

EX:

pytest tests --prj terraform-project-a

As parallel

pytest tests --prj <project name defined in YAML> -n <number of processes>

EX:

pytest tests --prj terraform-project-a -n 3

Render report differences of all plans

python report.py

Then, report will be render to ./report.md .
