ERROR Bootstrap {node validation exceptio}

I'm having a problem installing my Elastic for the first time, I've already run it before in the lab, but when I try again on other machines I get this message below:

[ERROR] [o.e.b.Bootstrap] [[$ jarvis]] node validation exception
[1] bootstrap checks failed
[1]: the default discovery settings are unsuitable for production use; at least one of [discovery.seed_hosts, discovery.seed_providers, cluster.initial_master_nodes] must be configured

I realemnet I do not know where it happens, I already looked in the forum and documentation but I did not get a solution that would help me.

Hi @jcesar_key, the solution is right there in the error message:

Here is a link to a page of the docs that I hope will help:

I've even looked at this before, but it does not apply because I have a single node in my cluster, not having a master, a, and a host.

A one-node cluster is still a cluster. It still has a master and still needs to be bootstrapped, if only to tell the node whether it's supposed to be joining a larger cluster or not. You need to set cluster.initial_master_nodes.

Sorry, I understood now what you said, I did it and it worked, thank you very much.
