When delete unused service with multiple repositories deployment, service and scheduled task settings exists for each repository. Then, only matches between template-group and ecs task-definition's environment TEMPLATE_GROUP value are targeted.

• no-set-tags (optional): Do Not Set the ecs task-definition's environment in ecs service tags. (default: true)
• no-get-tags (optional): Do Not Get the ecs task-definition's environment in ecs service tags. (default: true)
• get-task-definition-environment: (optional): Get the task-definition's environment in task definition. If this value is true, Get the all services task definition. (default: false)

• test-templates (optional): test templates. do not deploy. (default: false)

service and task-definition settings. Details are described later.

• services-yaml (required): ecs service and task-definition settings file.
• environment-yaml (required): jinja2 template input json data file. environment: parameter is required. only same task-definition's environment ENVIRONMENT service is deployed.
• environment-yaml-dir : for test-templates. all files below directory is loaded.

or

• task-definition-template-dir (required): ecs task-definition jinja2 template files directory. all files below directory is loaded.
• task-definition-json (required): jinja2 template input json data file.
