Sceptre: How to reference the current StackName in template file

[andyoll]

Is there a way to access default stack name from jinja template?
If not, is there a way to access it from within stack config file - then I can set a custom variable within namespace 'sceptre_user_data'.
I guess I could write a custom resolver, but I'm imagining it must already be available somehow.
Thanks.

Adding it to sceptre_user_data would surely work, you dont need to write a custom resolver for it. However, I am not sure if the stack name is automatically available to the jinja or not. @andyoll

@andyoll did @ankitml answer your question?

template name or entire stack name?
file name is {{ self._TemplateReference__context.name }}
stack name can be derived from a few variables and passed as sceptre_user_data
I think it would be {{ environment_config.project_code }}-{{ environment_path | join('-') }}-{{ self._TemplateReference__context.name[:-5] }} (however you'd be better of using the pseudo parameter (https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/pseudo-parameter-reference.html#cfn-pseudo-param-stackname))

I'm looking to do the same sort of thing. I want to pass the stack name to the cmd hook. Is this possible? Something like this..

template_path: templates/ExternalBucket.yaml
stack_name: TestStudy
parameters:
  SynapseUserName: "zippa"
hooks:
  after_create:
    - !cmd "BucketHelper.sh {{ stack_config.stack_name }}"

Answering my own question. What I'm trying to do seems possible only in V2.

I don't think it is resolved yet!
