If you don't need to have a cluster of multiple nodes, that's probably fine.

else, if I need it ,I must configure my elasticsearch engine settings ?
If you can please provide me a link for documentation thanks and have a nice day

You need to set network.host correctly and remove the discovery setting you just added.
