Anomalous cloud module
I don't understand how to use the template_parameters parameter correctly ( http://docs.ansible.com/ansible/cloudformation_module.html )
So it looks like I could use this parameter to override some parameter in the template. Very simple configuration
sandbox_cloudformation.yml
---
- name: Sandbox CloudFormation
hosts: localhost
connection: local
gather_facts: false
tasks:
- name: Launch Ansible CloudFormation Stack
cloudformation:
aws_access_key: "{{ aws_access_key }}"
aws_secret_key: "{{ aws_secret_key }}"
stack_name: "{{ aws_default_cloudformation_stack_name }}"
state: "present"
region: "{{ aws_default_region }}"
disable_rollback: true
template: "files/cloudformation.yml"
args:
template_parameters:
GroupDescription: "Sandbox Security Group"
cloudformation.yml
---
AWSTemplateFormatVersion: '2010-09-09'
Description: Sandbox Stack
Resources:
SandboxSecurityGroup:
Type: AWS::EC2::SecurityGroup
Properties:
GroupDescription: "DEMO"
SecurityGroupIngress:
- IpProtocol: tcp
FromPort: '80'
ToPort: '80'
CidrIp: 0.0.0.0/0
- IpProtocol: tcp
FromPort: '22'
ToPort: '22'
CidrIp: 0.0.0.0/0
But I got the following error:
fatal: [127.0.0.1]: FAILED! => {"changed": false, "failed": true, "msg": "Parameter values specified for a template which does not require them."}
Also, I got this error if I try to use for example
template_parameters:
KeyName: "{{ aws_default_keypair }}"
InstanceType: "{{ aws_default_instance_type }}"
Also, consult the best approach for using the cloudformation module for Ansible. Maybe the best way is to create a cloud formation template and use it in the next step? How..
- name: Render Cloud Formation Template
template: src=cloudformation.yml.j2 dest=rendered_templates/cloudformation.yml
- name: Launch Ansible CloudFormation Stack
cloudformation:
template: "rendered_templates/cloudformation.yml"
Thanks in advance!

You can use template_parameters
to pass parameters to the CloudFormation template. In the template, you will refer to the parameters with Ref
. In your case:
Playbook:
...
args:
template_parameters:
GroupDescriptionParam: "Sandbox Security Group"
...
template:
...
Resources:
SandboxSecurityGroup:
Type: AWS::EC2::SecurityGroup
Properties:
GroupDescription:
Ref: GroupDescriptionParam
...
See http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-ec2-security-group.html#w1ab2c19c12d282c19 for CloudSormation AWS SecurityGroup template examples.
Instead of using arguments template_parameters
in the Ansible module, cloudformation
I found it handy to create a Jinja2 template, convert it to a CloudFormation template using the Ansible module template
, as at the end of your question. Using this approach, you can skip args
and template_parameters
the module cloudformation
.
For example:
- name: Generate CloudFormation template
become: no
run_once: yes
local_action:
module: template
src: "mycloudformation.yml.j2"
dest: "{{ cf_templ_dir }}/mycloudformation.yml"
tags:
- cloudformation
- cf_template
- name: Deploy the CloudFormation stack
become: no
run_once: yes
local_action:
module: cloudformation
stack_name: "{{ cf_stack_name }}"
state: present
region: "{{ ec2_default_region }}"
template: "{{ cf_templ_dir }}/mycloudformation.yml"
register: cf_result
tags:
- cloudformation
- name: Show CloudFormation output
run_once: yes
become: no
debug: var=cf_result
tags:
- cloudformation
And mycloudformation.yml.j2:
