Search guard with single node


I’am using searchGuard configuration with one node cluster, I tried to disable inter node encryption according to my understanding is not possible?

if this is not possible, what is the interest of having encryption for a single node?

thanks for your answer

What is the interest of having only a single node? You can not run Elasticsearch in production with a single node and for development/test/evaluation you can use the demo installer/certificates.

I totally agree, I am dealing with a client who has required a single node, and who does not want to pay a certificate for nothing

You do not need to pay for a certificate at all. For example, you can use our TLS tool to generate as many production-ready certificates as required:

The tool will also generate configuration snippets which you can copy&paste to elasticsearch.yml.
