Description Matt Wringe 2016-08-15 20:49:10 UTC
Description of problem:

The events list used to list output from lifecycle hooks (eg readiness and lifecycle probes).

Without these messages from the lifecycle hooks it can be debugging certain situations very difficult. It also means we can't provide messages to users as to why the hook failed.

Comment 1 Michal Fojtik 2016-08-16 12:35:38 UTC
@mwringe are you referring to deployment hooks (pre/mid/post) and that they are not reporting errors to events OR you are referring to liveness and readiness probes not being reported in events?

Comment 2 Matt Wringe 2016-08-16 14:14:15 UTC
liveness and readiness probes, we used to get any output that these probes produced.

Comment 3 Andy Goldstein 2016-08-17 14:00:36 UTC
Please don't open bugs in both GitHub and here. Since you have this one, I'm going to close the GitHub issue (

Comment 4 Andy Goldstein 2016-08-17 14:01:35 UTC
This is specific to exec probes. There is a regression in Kube 1.3 that makes it so the output from exec probes is not included in the events.

Comment 5 DeShuai Ma 2016-08-23 06:44:28 UTC
Test on v3.3.0.24-dirty, "Readiness" event shows correctly
1. Create a pod with readiness exec probe
$ oc create -f
2. Check event shows correctly.
[root@openshift-107 ~]# oc get event -n dma|grep "Readiness probe failed"

Comment 6 DeShuai Ma 2016-08-23 06:45:14 UTC
[root@openshift-107 ~]# oc get event -n dma|grep "Readiness probe"
