Doc Type: Bug Fix
Doc Text:
Cause: Pod status of 'failed' was displayed instead of the reason when a pod was evicted. Consequence: It was more difficult to tell when a pod was failing because it was evicted. The user had to drill down into the details to see that the reason. Fix: When a pod is failing due to eviction, show it's status as 'Evicted' instead of 'Failed' Result: Pod's failing due to eviction now show 'Evicted' in the status field of the pod list and details pages.

Description Clayton Coleman 2019-04-01 17:05:40 UTC
An evicted pod looks like:

  phase: Failed
  message: >-
    The node was low on resource: ephemeral-storage. Container web was using
    832Ki, which exceeds its request of 0. 
  reason: Evicted
  startTime: '2019-03-28T05:29:41Z'

In the 3.11 cluster this was shown as a "Failed" pod with no additional info.  We need to show the reason next to failed, and probably show the message in the container status. Note that there is no container status, which probably confused the console.

Please verify that 4.1 correctly handles evicted pods (and consider including failure reason in pod status display).

The CLI shows "Evicted" instead of "Failed" because this is such an important condition.

https://github.com/openshift/console/pull/1379 for 3.11 is not merged yet.

Comment 5 Samuel Padgett 2019-04-04 13:25:04 UTC
The 3.11 fix has merged now. Note that we have only back-ported this fix to the 3.11 admin console and have not made any changes to the developer console.

1. Create some Evicted pods
# oc get pods
NAME                 READY     STATUS      RESTARTS   AGE
django-ex-10-build   0/1       Completed   0          7m
django-ex-11-build   0/1       Completed   0          6m
django-ex-11-wbt5s   0/1       Pending     0          3m
django-ex-11-wvmcd   0/1       Evicted     0          6m
django-ex-12-build   0/1       Evicted     0          5m
django-ex-13-build   0/1       Evicted     0          5m
django-ex-14-build   0/1       Evicted     0          5m
django-ex-15-build   0/1       Evicted     0          5m
django-ex-6-g7tjm    0/1       Evicted     0          47m
django-ex-7-build    0/1       Completed   0          44m
django-ex-8-build    0/1       Completed   0          39m
django-ex-9-build    0/1       Completed   0          8m

2. Check reason
# oc get pods django-ex-11-wvmcd -o yaml
apiVersion: v1
kind: Pod
  message: 'The node was low on resource: ephemeral-storage. Container django-ex was
    using 108Ki, which exceeds its request of 0. '
  phase: Failed
  reason: Evicted
  startTime: 2019-04-16T06:14:21Z

3. login to admin console, goes to Workloads -> Pods page, Pod status is shown as 'Evicted', see attachment
4. Verified on openshift v3.11.106
