Test Submission API should use Target Identity Endpoint UUID |
---|
story: "Use keystone uuid with cloud id" |
In order to ensure that multiple test runs are attributed to the same cloud, |
test runner needs to use a consistent, discoverable and unique identifier |
for each cloud test. This allows multiple users to correlate results from |
the same cloud. |
Problem description |
Refstack is designed to have minimal user security and configuration overhead; consequently, there are no mechanisms in the short term to ensure that a user's test results are authorized (see note). To create valid results, refstack needs a way to know when multiple runs are against the same targets so that comparisons are valid.
> Note: In the future, Refstack will include user authentication. At that point it will be possible to associate uploaded data to users and vendors in an authoritative way.
To solve this problem, refstack needs a unique handle for each cloud tested that is unique and also discoverable to the test runner.
Some requirements:
- No round trips to refstack before a test is submitted (do not pre-create cloud)
- Minimal trust of users (do not require user credentials for uploads)
- Users should not be expected to remember cloud IDs
- Multiple users of same cloud should be tracked together
Proposed change
When test runner submits results, it should submit with the Identity Endpoint UUID (aka Keystone end point under serviceCatalog/service["identity"]/endpoint[?id]).
The refstack API should accept EITHER the user's created refstack cloud ID or the discovered Endpoint UUID. If the refstack cloud ID is passed and no cloud exists then refstack should create a new refstack cloud.
Alternatives
Refstack could use a different endpoint for the ID
Refstack could stop using its own cloud ID and only use endpoint IDs
Possible addition: we may want to also track the cloud endpoint URL. This could be a possible added field for the JSON upload. While this will help identify clouds, it could also reveal more information than the user wants disclosed. We should only implement this with user permission.
Data model impact
We have to add the endpoint ID as a field into the Cloud model.
REST API impact
The Test Upload API needs to be modified to accept either the Test ID or the endpoint UUID. If the endpoint UUID is not in the URL then it should be included in the JSON payload.
Security impact
Improvement: this helps reduce the need of passing refstack authentication to ensure that cloud results are linked to individual clouds or users.
Notifications impact
None.
Other end user impact
Users will not have to pre-create clouds before using refstack.
Users will have to be able to assign clouds to endpoint UUIDs.
Performance Impact
Should improve performance because round trips on result uploads are avoided.
Other deployer impact
None.
Developer impact
Should simplify developer work.
Implementation
Assignee(s)
TBD
Work Items
- determine forumula for endpoint UUID (if any needed)
- get and add cloud epid to results upload
- add cloud epid to model
- update api to response correctly for epid lookup
Dependencies
API v1 spec.
Testing
We need to validate the endpoint IDs correctly resolve to clouds.
Documentation Impact
We should explain how clouds are identified in the documentation so that users will understand the impact of re-installing and how to keep results together even if the cloud changes.
We will also have to explain how to associate results to a user managed cloud.
