Description DeShuai Ma 2016-11-07 07:29:52 UTC

Description of problem:
when get heapster version using latest metrics-heapster image, heapster crash with error.
This should be a bug in upstream v1.2.0, now our metrics-heapster version is v1.2.0 too.

Version-Release number of selected component (if applicable):
openshift v3.4.0.22+5c56720
brew-pulp-docker01.web.prod.ext.phx2.redhat.com:8888/openshift3/metrics-heapster:3.4.0
image id: e4c76b3a21e9

How reproducible:
Always

Steps to Reproduce:
1. [root@openshift-143 ~]# docker run -it --entrypoint=/bin/sh brew-pulp-docker01.web.prod.ext.phx2.redhat.com:8888/openshift3/metrics-heapster:3.4.0
    sh-4.2# /bin/heapster version

Actual results:

Expected results:
1.Get heapster version correctly.

Additional info:
In latest heapster upstream get version corectly:
[root@ip-172-18-6-200 heapster]# ./heapster version
I1107 01:45:29.756144    5553 heapster.go:65] ./heapster version
I1107 01:45:29.756344    5553 heapster.go:66] Heapster version 1.2.0

Comment 1 DeShuai Ma 2016-11-07 07:45:32 UTC

We can fix this bug in upstream v1.2.0 then rebuild our metrics-heapster image.

Comment 2 DeShuai Ma 2016-11-07 09:36:18 UTC

Create a upstream issue: https://github.com/kubernetes/heapster/issues/1370

Comment 3 Matt Wringe 2016-11-07 14:43:14 UTC

There is no 'heapster version' command.

Running this both in 1.2.0 and master results in an error message that Heapster could not start, the only difference is the error message being returned (and it seems that master does handle this a bit better).
