Hey,
I really liked the v2 Heat API (as proposed in Create a new v2 Heat API
<https://blueprints.launchpad.net/heat/+spec/v2api>) and I think it
makes a lot of sense.
One of the proposed changes is to “Remove template_url from the request
POST”, so the template will be passed using the “template” parameter in
the request body.
Could someone please elaborate how exactly Heat Orchestration Templates
written in YAML will be embedded in the body?
As I understand the YAML template should be inserted as string otherwise
JSON parsers will not be able to parse the JSON body.
If indeed the template is inserted as string, as far as I know, JSON
does not support multiline strings and the available workarounds are not
so pretty and require escaping.
The escaping issue gets more complicated when "UserData" is used in the
YAML.
Will the “template_url” be removed and if so how will the “template”
contain the YAML template?
Oh, that would be sad indeed. We're just looking at this pattern in AWS:
http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/quickref-stack.html
And using that in heat as well would be very welcome.
Cheers,
