Fixed In Version:		Doc Type:	Bug Fix
Doc Text:	Cause: keepYoungerThan is expected to be an integer. It is an integer that defines a minimal image age in nanoseconds. Consequence: It's inconvenient to use nanoseconds to tune the pruner. Fix: Deprecate keepYoungerThan and introduce a new field named keepYoungerThanDuration. Result: keepYoungerThanDuration can be set to "60m" and similar values.	Story Points:	---

Description Odilon Sousa 2020-05-12 21:26:08 UTC

Description of problem: 

While trying to set keepYoungerThan, the client returns spec.keepYoungerThan in body must be of type integer: "string"

Version-Release number of selected component (if applicable):

Openshift Container Platform 4.4

How reproducible:

$ cat <<EOF >>image-pruner.yaml
apiVersion: imageregistry.operator.openshift.io/v1
kind: ImagePruner
metadata:
  name: imageprunertest
spec:
  schedule: "*/0 * * * *"
  suspend: false
  keepTagRevisions: 3
  keepYoungerThan: 60m
  startingDeadlineSeconds: 60
  successfulJobsHistoryLimit: 3
  failedJobsHistoryLimit: 3
EOF

$ oc create -f image-pruner.yaml


Actual results:

The ImagePruner "imageprunertest" is invalid: spec.keepYoungerThan: Invalid value: "string": spec.keepYoungerThan in body must be of type integer: "string"

Expected results:

The object to be created without problem

Comment 5 Wenjing Zheng 2020-05-28 02:49:37 UTC

Below error still return when define like "keepYoungerThan: 60m" with 4.5.0-0.nightly-2020-05-27-174108:
# imagepruners.imageregistry.operator.openshift.io "cluster" was not valid:
# * spec.keepYoungerThan: Invalid value: "string": spec.keepYoungerThan in body must be of type integer: "string"

Below setting can be saved:
spec:
  failedJobsHistoryLimit: 3
  keepTagRevisions: 3
  keepYoungerThan: 60
  schedule: ""
  successfulJobsHistoryLimit: 3
  suspend: false

Comment 6 Wenjing Zheng 2020-05-28 02:55:15 UTC

This config change works:
spec:
  failedJobsHistoryLimit: 3
  keepTagRevisions: 3
  keepYoungerThan: 60
  keepYoungerThanDuration: 60m

I will report a doc bug to deprecate "keepYoungerThan".

Comment 7 Wenjing Zheng 2020-05-28 02:59:23 UTC

If keepYoungerThan is deprecated, can we pop up a warning let user know to use keepYoungerThanDuration when user wants to config keepYoungerThan?

Comment 8 Oleg Bulatov 2020-05-28 10:06:47 UTC

Unfortunately we cannot change the type of keepYoungerThan from an integer to string.

We should replace keepYoungerThan with keepYoungerThanDuration in docs. It's better to almost completely remove keepYoungerThan from documentation, we can just mention that this field exists and shouldn't be used.

OK, get it, thanks! I will add your suggestion to the doc bug: https://bugzilla.redhat.com/show_bug.cgi?id=1840973 . Feel free to change this bug back to ON_QA.
