I'm trying to index from elastic cloud locally in a docker container (7.4.0) but having a hard time whitelisting the remote host.
I've added this to the ES_OPTS and can see this option being logged when ES starts:
However, when I try to reindex from that host, I get an error about the host not being whitelisted. So it is ignoring the setting.
What do I need to do to make this work? I've tried variations of this without the brackets, with quotes, etc.
