Example Spec - The title of your blueprint
|
|
==========================================
|
|
|
|
Include the URL of your launchpad blueprint:
|
|
|
|
https://blueprints.launchpad.net/tripleo
|
|
|
|
Introduction paragraph -- why are we doing anything? A single paragraph of
|
|
prose that operators can understand.
|
|
|
|
Some notes about using this template:
|
|
|
|
* Your spec should be in ReSTructured text, like this template.
|
|
|
|
* Please wrap text at 80 columns.
|
|
|
|
* The filename in the git repository should match the launchpad URL, for
|
|
example a URL of: https://blueprints.launchpad.net/tripleo/+spec/awesome-thing
|
|
should be named awesome-thing.rst
|
|
|
|
* Please do not delete any of the sections in this template. If you have
|
|
nothing to say for a whole section, just write: None
|
|
|
|
* For help with syntax, see http://sphinx-doc.org/rest.html

Problem Description
|
|
===================
|
|
|
|
A detailed description of the problem:
|
|
|
|
* For a new feature this might be use cases. Ensure you are clear about the
|
|
actors in each use case: End User vs Deployer
|
|
|
|
* For a major reworking of something existing it would describe the
|
|
problems in that feature that are being addressed.
|
|
|
|
|
|
Proposed Change
|
|
===============
|
|
|
|
Here is where you cover the change you propose to make in detail. How do you
|
|
propose to solve this problem?
|
|
|
|
If this is one part of a larger effort make it clear where this piece ends. In
|
|
other words, what's the scope of this effort?
|
|
|
|
Alternatives
|
|
------------
|
|
|
|
What other ways could we do this thing? Why aren't we using those? This doesn't
|
|
have to be a full literature review, but it should demonstrate that thought has
|
|
been put into why the proposed solution is an appropriate one.
|
|
|
|
Security Impact
|
|
---------------
|
|
|
|
Describe any potential security impact on the system. Some of the items to
|
|
consider include:
|
|
|
|
* Does this change touch sensitive data such as tokens, keys, or user data?
|
|
|
|
* Does this change involve cryptography or hashing?
|
|
|
|
* Does this change require the use of sudo or any elevated privileges?
|
|
|
|
* Does this change involve using or parsing user-provided data? This could
|
|
be directly at the API level or indirectly such as changes to a cache layer.
|
|
|
|
* Can this change enable a resource exhaustion attack, such as allowing a
|
|
single API interaction to consume significant server resources? Some examples
|
|
of this include launching subprocesses for each connection, or entity
|
|
expansion attacks in XML.
|
|
|
|
For more detailed guidance, please see the OpenStack Security Guidelines as
|
|
a reference (https://wiki.openstack.org/wiki/Security/Guidelines). These
|
|
guidelines are a work in progress and are designed to help you identify
|
|
security best practices. For further information, feel free to reach out
|
|
to the OpenStack Security Group at openstack-security@lists.openstack.org.
|
|
|
|
Other End User Impact
|
|
---------------------
|
|
|
|
Are there ways a user will interact with this feature?
|
|
|
|
Performance Impact
|
|
------------------
|
|
|
|
Describe any potential performance impact on the system, for example
|
|
how often will new code be called, and is there a major change to the calling
|
|
pattern of existing code.
|
|
|
|
Examples of things to consider here include:
|
|
|
|
* A small change in a utility function or a commonly used decorator can have a
|
|
large impacts on performance.
|
|
|
|
Other Deployer Impact
|
|
---------------------
|
|
|
|
Discuss things that will affect how you deploy and configure OpenStack
|
|
that have not already been mentioned, such as:
|
|
|
|
* What config options are being added? Should they be more generic than
|
|
proposed (for example a flag that other hypervisor drivers might want to
|
|
implement as well)? Are the default values ones which will work well in
|
|
real deployments?
|
|
|
|
* Is this a change that takes immediate effect after its merged, or is it
|
|
something that has to be explicitly enabled?
|
|
|
|
* Please state anything that those doing continuous deployment, or those
|
|
upgrading from the previous release, need to be aware of. Also describe
|
|
any plans to deprecate configuration values or features. For example, if we
|
|
change the directory name that instances are stored in, how do we handle
|
|
instance directories created before the change landed? Do we move them? Do
|
|
we have a special case in the code? Do we assume that the operator will
|
|
recreate all the instances in their cloud?
|
|
|
|
Developer Impact
|
|
----------------
|
|
|
|
Discuss things that will affect other developers working on OpenStack.
|
|
|

Implementation
|
|
==============
|
|
|
|
Assignee(s)
|
|
-----------
|
|
|
|
Who is leading the writing of the code? Or is this a blueprint where you're
|
|
throwing it out there to see who picks it up?
|
|
|
|
If more than one person is working on the implementation, please designate the
|
|
primary author and contact.
|
|
|
|
Primary assignee:
|
|
<launchpad-id or None>
|
|
|
|
Other contributors:

|
|
|
|
Work Items
|
|
----------
|
|
|
|
Work items or tasks -- break the feature up into the things that need to be
|
|
done to implement it. Those parts might end up being done by different people,
|
|
but we're mostly trying to understand the timeline for implementation.
|
|
|
|
|
|
Dependencies
|
|
============
|
|
|
|
* Include specific references to specs and/or blueprints in tripleo, or in other
|
|
projects, that this one either depends on or is related to.
|
|
|
|
* If this requires functionality of another project that is not currently used
|
|
by Tripleo (such as the glance v2 API when we previously only required v1),
|
|
document that fact.
|
|
|
|
* Does this feature require any new library dependencies or code otherwise not
|
|
included in OpenStack? Or does it depend on a specific version of library?
|
|
|
|
|
|
Testing
|
|
=======
|
|
|
|
Please discuss how the change will be tested.
|
|
|
|
Is this untestable in CI given current limitations (specific hardware /
|
|
software configurations available)? If so, are there mitigation plans (3rd
|
|
party testing, gate enhancements, etc).
|
|
|
|
|
|
Documentation Impact
|
|
====================
|
|
|
|
What is the impact on the docs? Don't repeat details discussed above, but
|
|
please reference them here.
|
|
|
|
|
|
References
|
|
==========
|
|
|
|

|
|
references are unavailable. Examples of what you could include are:
|
|
|
|
* Links to mailing list or IRC discussions
|
|
|
|
* Links to notes from a summit session
|
|

|
* Links to relevant research, if appropriate
|
|
|
|
* Related specifications as appropriate (e.g. if it's an EC2 thing, link the EC2 docs)
|
|
|
|
* Anything else you feel it is worthwhile to refer to
