Elasticsearch remote cluster reindexing wildcard

Hi there,

I am trying to use -e reindex.remote.whitelist="*" in my docker run command to allow all domains in whitelist.
But I am getting the following error when I try to run this:-

Exception in thread "main" org.elasticsearch.common.settings.SettingsException: Failed to load settings from [overrides.yml]

in 'reader', line 2, column 27:
reindex.remote.whitelist: *
unexpected character found
in 'reader', line 2, column 28:
reindex.remote.whitelist: *
Can someone please suggest the solution here.
Thanks in advance!


What version?

Pretty sure you have a syntax error you need host:port

Remote hosts have to be explicitly allowed in elasticsearch.yml using the reindex.remote.whitelist property. It can be set to a comma delimited list of allowed remote host and port combinations. Scheme is ignored, only the host and port are used. For example:

So if you want to allow everything ...

reindex.remote.whitelist: "*:9200"

or in your case



Version is 8.7.0,
This is working for me "'*:*'"
