imports allow the author of a blueprint to reuse blueprint files or parts of them and use predefined types (e.g. from the types.yaml file).

Note

Beginning with definitions version cloudify_dsl_1_3, you can also import inputs, node_templates and outputs multiple times.

Declaration

  
imports:
  - ...
  - ...

Example

  

imports:
  - http://www.getcloudify.org/spec/cloudify/3.3/types.yaml
  - my_yaml_files/openstack_types.yaml

node_templates:
  vm:
    type: cloudify.openstack.nodes.Server
  webserver:
    type: cloudify.nodes.WebServer

In the above example, we import the default types.yaml file provided by Cloudify which contains the cloudify.nodes.WebServer node type and a custom YAML we created for our custom OpenStack plugin containing the cloudify.openstack.nodes.Server node type.

A few important things to know about importing YAML files:

Imported files can be either relative to the blueprint’s root directory or be a URL (as seen above).
You can use imports within imported files and nest as many imports as you like.
An error will be raised if there are cyclic imports (i.e. a file is importing itself or importing a file which is importing the file that imported it, etc..)
Groups cannot be imported and can only be defined in the main blueprint file
The tosca_definitions_version as stated here must match between imported files.
