Terraform Module to run ansible playbooks.

Module usage

Add special section to the playbook

You must add this section on the top of all playbooks that will be used for provisioning.

This will add a dynamic inventory to target the host that needs provisioning.

e.g. ../ansible/playbooks/playbook.yml

• Create a runtime inventorty with an ip address of a host
• Wait for target host is ready for ssh connection

---
- hosts: localhost
  gather_facts: True
  check_mode: no
  tasks:
  - name: Add public ip addresses to an dynamic inventory
    add_host:
      name: "{{ host }}"
      groups: all

  - local_action: wait_for port=22 host="{{ host }}" search_regex=OpenSSH delay=10

- hosts: all
  gather_facts: False
  check_mode: no
  become: True
  tasks:
  - name: Install python 2.7
    raw: >
      test -e /usr/bin/python ||
      (
        (test -e /usr/bin/apt-get && (apt-get -y update && apt-get install -y python)) ||
        (test -e /usr/bin/yum && (yum makecache fast && yum install -y python))
      )
    args:
      creates: /usr/bin/python

Create an aws instance

resource "aws_instance" "web" {
  ami           = "ami-408c7f28"
  instance_type = "t1.micro"
  tags {
    Name        = test1
  }
}

Apply the provisioner module to this resource

module "ansible_provisioner" {
   source    = "github.com/cloudposse/tf_ansible"

   arguments = ["--user=ubuntu"]
   envs      = ["host=${aws_instance.web.public_ip}"]
   playbook  = "../ansible/playbooks/test.yml"
   dry_run   = false

}
