I have a requirement to call a Heat Template ( Child ) from Another Heat Template ( Parent ).

For the following I am using the below in template:

"Resources" : {

"myStackWithParams" : {
     "Type" : "AWS::CloudFormation::Stack",
     "Properties" : {
         "TemplateURL" : "/home/amdocs/Documents/RunUnixCommandHeat.template"       // Localpath    
       }
},

In above case getting error i.e IOError: Invalid URL scheme. I tries with file:///home/amdocs/Documents/RunUnixCommandHeat.template as TemplateURL. Getting same error.

Another thing that I tried is access a standard template of Amazon:

"Resources" : {

"myStackWithParams" : {
     "Type" : "AWS::CloudFormation::Stack",
     "Properties" : {
         "TemplateURL" : "https://github.com/openstack/heat-templates/blob/master/cfn/F17/WordPress_Single_Instance_Rackspace_Cloud_Servers.template"           
       }
}

This also not working.

As per the link http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-stack.html suggested the template must be stored on an Amazon S3 bucket.

Is there any way I can connect to template other than the Amazon one. Can I specify a local heat template file name, what is the url should specified in TemplateURL parameter?

Any tips or suggestion is highly appreciated.

Thanks in Advance for the help.
