kunstkomputer opened a new issue, #799:
URL: https://github.com/apache/solr-operator/issues/799
The Readiness Probes of the chart always return success as the command of
the authenticated wget is always piped into a grep command which always has the
return code `0` regardless weather they were able to access the Endpoint or
not. This leads to the solr-pod starting clean and kept alive by k8s even
though the authentication to the endpoints is actually failing. In my opinion
this shall lead to the pod not becoming ready.
The same applies to the Liveness Probes respectively.
the generated yaml of the probes from the `solr pod` by the solr-operator:

Downside is that without the `grep -v` the basicAuth Password may be logged.
I can't figure out where it may be logged but, I assume the `grep -v` may have
been introduce to suppress the logging of the credentials.
