There will be additional method in Hot Rod Client configuration (ConfigurationBuilder#<wbr>addServerMapping(String mappingClass)) which will be responsible for mapping external addresses to internal and vice-versa.</div></div><div><br></div><div>Thoughts?</div><div><br></div><div>Thanks,</div><div>Sebastian</div><div><br></div><div>[1] <a href="https://github.com/kubernetes/community/pull/446" target="_blank">https://github.com/<wbr>kubernetes/community/pull/446</a></div><div>[2] <a href="https://github.com/slaskawi/external-ip-proxy" target="_blank">https://github.com/<wbr>slaskawi/external-ip-proxy</a></div></div>
