The Yellow status means that there is a risk of losing data if something goes wrong with your shards.

To get it green you should at least have another node. I mean you should create a cluster.

The machine you installed Elastic on is considered as a Node (one-node). You should install another instance of Elastic
in another machine (or VM) - you can simply copy the current installation to another machine. And modify the config files of the two instances to communicate together. The config file should be in the installation directory of your Elastic. An finally, when you create your indices you specify the number of replicate (example if you have 3 nodes then you can set the number of replicates to 2 or 3). Hope this will help.

Or set the number of replicas to 0 for each index.
Or ignore this. It's not that important if you want only one node.
