smoke-test: only "kubectl logs" on failure

maelvls · maelvls · commit 3e224695537d · 2021-07-06T11:45:42.000+02:00
Running stern immediately (kubectl logs was giving similar results), the
following error would show:

  Error: failed to set up watch: failed to set up watch: unknown (get pods)

To get around this issue, the logs are now only fetched on error.
