We will fix this in kube so as such pod specs are rejected via validation.

Comment 2 Hemant Kumar 2018-03-08 17:28:56 UTC
Opened PR in upstream - https://github.com/kubernetes/kubernetes/pull/60934

Comment 3 Hemant Kumar 2018-03-12 17:28:53 UTC
The upstream PR is stalled for a bit because it can cause existing pod objects to become invalid (and hence potentially undeletable and unupdatable).

Comment 5 Hemant Kumar 2018-05-29 13:45:45 UTC
I am going to close this BZ, since upstream PR for tightening validations will break upgrades - we will leave the underlying behaviour as it is.

There are workarounds available and behaviour of "oc" command has already been fixed, so as such it should affect no users.
