Description rdobosz 2021-01-13 08:14:43 UTC 
Description of problem:

As of Kubernetes 1.16 deprecation of selLink has been announced. With Kubernetes 1.20 it will be disabled, thus it will not be propagated with all the objects sent/retrieved from API.

In Kuryr-Kubernetes there are several places where selLink information is used and relied on. 

How reproducible:

Steps to Reproduce:
1. Upgrade to Kubernetes 1.20 or pass parameter "--feature-gates=RemoveSelfLink=true" in versions prior to 1.20
2. Run the stack
3. Try to create some pod/deployment

Actual results:

Failure on Kuryr controller due to lack of selfLink key in several places

Expected results:

Create pod/deployment without any issue
Comment 4 rlobillo 2021-01-28 08:54:39 UTC 
Verified on OCP4.7.0-0.nightly-2021-01-27-110023 on OSP16.1 (RHOS-16.1-RHEL-8-20201214.n.3) with OVN-Octavia.

All kuryr-tempest-plugin, NP and Conformance tests are passing. Logs attached.

selflink is still enabled on OCP4.7 nightly builds, so tests are passing without actually testing the scenario where selflink is disabled. It is agreed that we will cover this as soon as selflink is disabled through our CI jobs.
