antform
Despite it's name, antform is not a form markup language for our arthropodous friends, it is actually a command line tool written in Go that converts a terraform state file into an ansible inventory file.
The idea is to use terraform to deploy your infrastructure and then configure it with ansible using the inventory produced by antform. It has currently only been tested with the triton terraform provider, so your mileage may vary.
Usage
Arguments
| Flag | Example | Description |
|---|---|---|
-f |
/path/to/terraform.tfstate |
Specify the path to the terraform.tfstate file, defaults to current directory terraform.tfstate. |
-t |
group |
Group the Terraform machines by tag, these exist in the attributes object and prefixed by tags.. This example would map to the key tags.group. |
Switches
| Flag | Description |
|---|---|
-h |
Displays the usage information. |
Note: Currently antform outputs to stdout and assumess that your tfstate file is in the same structure as the test terraform.tfstate file in this repo. This solves the problem in my specific use case, but adding support for other terraform providers wouldn't be too dificult, however I haven't bothered to check if the provider structs are the same as triton so give it a go.
Examples
antform outputs the data in your tfstate file, sorting each primary ip address by name:
~$ antform
[es-data-1]
192.160.0.1
[es-data-2]
192.160.0.2
[es-data-3]
192.160.0.3
antform can then split the machines by tags that you define in the your terraform machine configuration:
~$ antform
[elasticsearch]
192.160.0.1
192.160.0.2
192.160.0.3
