I have 2 ES docker clusters. I want to re-index some indexes from the smaller docker es cluster to my larger es docker cluster. When i follow the instructions to reindex i get the "not whitelisted in reindex.remote.whitelist" error.

since these aren't physical installs and everything is in containers, how do i go about whitelisting the old ip:9200 server so that I can re-index the indexes i need to move over to the new cluster?

Thanks,
