aci_rest: Using status="created" behaves differently than status="deleted"

[dagwieers]

ISSUE TYPE

• Bug Report

COMPONENT NAME

aci_rest

ANSIBLE VERSION

v2.4+

SUMMARY

If you use a REST payload with aci_rest using status="created" the action is not idempotent. The first time (when the object does not exist) it works (changed=True), but a subsequent call fails as the APIC returns an HTTP failure.

However, if you do the same for removing an object using status="deleted" the action is idempotent. So a subsequent call works (and does not report a change, changed=False) as one would expect.

This seems an implementation issue in the APIC.

PS If you would add status="created,modified" or simply status="modified" your task will be idempotent and it will not lead to failures on subsequent runs.

STEPS TO REPRODUCE

This will cause a failure on a subsequent create:

<aaaUserCert dn="uni/userext/user-admin/usercert-admin" data="-----BEGIN CERTIFICATE-----\r\nMII<snip>NGg\r\n-----END CERTIFICATE\r\n" name="admin" rn="usercert-admin" status="created"/>

This will not cause a failure on a subsequent removal:

<aaaUserCert dn="uni/userext/user-admin/usercert-admin" name="admin" rn="usercert-admin" status="deleted"/>

However using status="modified" will always work.

This report wants to highlight that creation and deletion have a different behaviour.

The vendor has been notified of this inconsistency.

I am not able to reproduce this on version 3.0(2k) running on sandboxapicdc.cisco.com.

Either the identified problem is more complex, or this is already fixed in a newer release.
