Terraformed Inventory
This is a little Go app which generates an dynamic Ansible ansible inventory from a [Terraform] tf state file. It allows one to spawn a bunch of VMs with Terraform, then (re-)provision them with Ansible. It's pretty neat.
Currently, only AWS and DigitalOcean are supported.
Installation
On OSX, install it with Homebrew:
brew install https://raw.github.com/adammck/terraform-inventory/master/homebrew/terraform-inventory.rb
This is only a tiny tool, so it's not in the main Homebrew repo. Feel free to add it, if you think that would be useful.
Usage
Ansible doesn't (seem to) support calling the inventory script with parameters,
so you can specify the path to the state file using the TI_TFSTATE environment
variable, like so:
TI_TFSTATE=deploy/terraform.tfstate ansible-playbook --inventory-file=terraform-inventory deploy/playbook.yml
Alternately, you can create a little shell script and call that. Something like:
#!/bin/bash
terraform-inventory $@ deploy/terraform.tfstate
Then run Ansible with the script as an inventory:
ansible-playbook --inventory-file=bin/inventory deploy/playbook.yml
Development
It's just a Go app, so the usual:
go get github.com/adammck/terraform-inventory
cd $GOPATH/adammck/terraform-inventory
go build
To test against an example statefile, run:
terraform-inventory --list fixtures/example.tfstate
terraform-inventory --host=web-aws fixtures/example.tfstate
To update the fixtures, populate fixtures/secrets.tfvars with your DO and AWS
account details, and run fixtures/update. You probably don't need to do this.
