Template

You put CloudFormation template files for stacks in the templates directory or its subdirectories.
For each stack, you specify the template file to use with the template property. It accepts a relative file path to the template file in the templates directory.
If you don't specify the template, Takomo looks for a template file using the relative file path to the current stack configuration file from the stacks directory.
Takomo supports both of the standard CloudFormation template file formats, i.e., JSON and YAML.
Example
Say, we have the following project.
.
├─ stacks
│  └─ application.yml
└─ templates
   └─ application-template.yml
In application.yml stack configuration file you can define the template property like so:
stacks/application.yml
template: application-template.yml
If you would omit the template property, Takomo would fallback to the default behaviour and look for a template file by name application.yml from the templates directory.
Inline template body
You can also inline the template body in a stack configuration file.
Example
template:
  inline: |
    Resources:
      VPC:
        Type: AWS::EC2::VPC
        Properties:
          CidrBlock: 10.0.0.0/16
  
Disabling dynamic template
By default, Takomo processes each template file with Handlebars templating engine. You can turn off this dynamic template processing by providing the template configuration with an object with two properties: filename and dynamic. The former specifies the relative file path to the template file in the templates directory., and the latter is an optional boolean to enable or disable dynamic processing.
Example
Use the object notation to disable dynamic template:
template:
  filename: networking.yml
  dynamic: false
Where to define
The template property can be defined only in stack configuration files.
Requirements
The template property must satisfy these requirements:
Must be a string or an object
