I installed elastic search in my local machine, I want to configure it as the only one single node in the cluster(Standalone Server). it means whenever I create a new index, it will only available to my server. It will not be accessible to other's server.
My current scenario these indexes are available to other servers (the servers are formed in a cluster), and they can make any changes to my indexes. But I don't want it.
I went through some other blogs but not getting best solution. So can you please let me know steps for same?

To run the Elasticsearch 7 Docker image in development mode, you should set discovery. type to single-node . At startup, the bootstrap checks are bypassed. The single node will elect itself as the master node and will not join a cluster with any other node.
Single node clusters are Dataproc clusters with only one node. This single node acts as the master and worker for your Dataproc cluster.
A quorum would be 2, but this means a loss of one node will make your cluster inoperable. A setting of 1 will allow your cluster to function but doesn't protect against the split-brain. It is best to have a minimum of three nodes.
I ve got the answer from http://elasticsearch-users.115913.n3.nabble.com/How-to-isolate-elastic-search-node-from-other-nodes-td3977389.html.
Kimchy : You set the node to local(true), this means it will not discover other nodes using network, only within the same JVM.
in elasticsearch/bin/elasticsearch.yml file
node.local: true # disable network in elasticsearch.yml
network.host: 0.0.0.0 discovery.type: single-node and make sure you have cluster.initial_master_nodes off
# cluster.initial_master_nodes: ["node-1", "node-2"] credited to @Chandan.
