show better error messages for failed RCs / pods #37

e.g. via the command line:

$ oc describe rc jenkins
Name:       jenkins
Image(s):   fabric8/jenkins
Selector:   component=jenkins,provider=fabric8
Labels:     component=jenkins,provider=fabric8
Replicas:   0 current / 1 desired
Pods Status:    0 Running / 0 Waiting / 0 Succeeded / 0 Failed

whereas from the UI the RC looked fine

Weird how the pod status shows 0 succeeded but also 0 failed :-) I guess perhaps the status field isn't updated properly.

jstrachan commented 9 years ago

yeah - in this particular case - there's no pods created ever; nor can I see any kind of status on the RC

actually the data thats available from oc describe pod foo is pretty nice; we should include it into hawtio-kubernetes somewhere:

jstrachan:/workspace/java/$ oc describe pod letschat-sqmi9
Name:               letschat-sqmi9
Image(s):           mongo,fabric8/lets-chat:latest
