===========================================

Heat template migrate resources' properties
|
||||
===========================================
|
||||
|
||||
https://blueprints.launchpad.net/heat/+spec/heat-template-port
|
||||
|
||||
Heat does not provide api/cli to migrate the given template from old heat
|
||||
version to later.
|
||||
|
||||
Problem description
|
||||
===================
|
||||
|
||||
Heat is being released inline with each Openstack release and there is a chance
|
||||
that resource properties and attributes might have changed and/or deprecated
|
||||
across these releases. A user may wish to migrate the template to current
|
||||
version which was created during earlier version say juno. Currently heat
|
||||
does not support it.
|
||||
|
||||
Proposed change
|
||||
===============
|
||||
|
||||
Heat already having mechanism to define the translation rule for each of the
|
||||
properties being deprecated by using translation.TranslationRule.
|
||||
This is being implemented in resource plugins in order to support migration
|
||||
to new property in place of deprecated one.
|
||||
|
||||
This feature could be updated with below command
|
||||
|
||||
``openstack orchestration template migrate -t <template-file> --output-format
|
||||
[json|yaml] --output-file <output-file>``
|
||||
|
||||
This command will migrate the given template file and will write the template
|
||||
output mentioned in output-format.
|
||||
|
||||
Command will provide messages of changes made to the deprecated properties in
|
||||
below format::
|
||||
|
||||
<resource-path> <property> <action> <details>
|
||||
|
||||
where:
|
||||
|
||||
*resource-path*
|
||||
Gives the resource path in the given template.
|
||||
|
||||
*property*:
|
||||
Property name to migrate to current version.
|
||||
|
||||
*action*:
|
||||
One of add, replace or delete.
|
||||
|
||||
*details*:
|
||||
Provides additional details about deprecation, if any.
