Fixes: #247
Validated by checking where klog ends up writing to by adding this
to
cmd/promxy/main.go
.Before the change, the call fails because it cannot write to
/tmp
but it successfully logs to stderr after the change.Looks like this happens specifically when using kubernetes service discovery from the promxy config file. This change is also in the current prometheus source: https://github.com/prometheus/prometheus/blob/master/cmd/prometheus/main.go#L328-L330
