t2a (Terrafirm To Ansible CLI)

This app is created to convert terraform outputs from state to valid ansible inventory file

How to use

Write Terraform HCL describing your infrastructure. Do not forget to write outputs.tf.

output "master_addresses" {
  value = join(", ",openstack_compute_instance_v2.k8s-masters-seed.network[0].fixed_ip_v4)
}

output "minions_adresses" {
  value = join(", ",openstack_compute_instance_v2.k8s-minions[*].network[0].fixed_ip_v4)
}

Then run

#If you not compiled t2a do so with go get && go build
terraform apply && ./t2a

You will get something like

all:
  children:
    master_addresses:
      hosts:
        10.219.150.27: 
        10.219.150.28: 
        10.219.150.30:
    minions_adresses:
      hosts:
        10.219.150.31: 
        10.219.150.32: 
        10.219.150.33:

Then you can do smth like:

ansible-playbook -u user -i inventory.yaml --private-key ~/.ssh/id_rsa your-playbook.yaml

Enjoy

Optional

You can use flags for set path to "terraform.tfstate" и "inventory.yaml" in you project. For example:

t2a -pathTFState="/myFolderIn/terraform.tfstate" -pathAnsible="/myFolderOut/inventory.yaml"
