Following docs, cannot connect to Dockerized ES via TransportClient

Elastic Stack Elasticsearch
1

Hello; I'm new to ElasticSearch. I've followed the official documentation on how to kick the tires using Docker.

Specifically, I've run the Docker image like so:

$ docker run -p 9200:9200 -p 9300:9300 -e "http.host=0.0.0.0" -e "transport.host=127.0.0.1" -e "xpack.security.enabled=false" docker.elastic.co/elasticsearch/elasticsearch:5.4.2

If I point my browser at http://localhost:9200/_cat/health, I get:

1498166019 21:13:39 docker-cluster yellow 1 1 3 3 0 0 3 0 - 50.0%

...which of course worries me, but fine, I don't really have any control over this.

Then I build my Java Client like so:

this.client = new PreBuiltTransportClient(Settings.builder()
                                      .put("cluster.name", "docker-cluster")
                                      .put("client.transport.sniff", true)
                                      .build())
  .addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("127.0.0.1"), 9300));

...and an attempt to get something results in the dreaded:

NoNodeAvailableException[None of the configured nodes are available: [{#transport#-1}{q00tH2RKTlCkXut03lYHOg}{127.0.0.1}{127.0.0.1:9300}]]

Which part of the official documentation explains why this doesn't work? Thanks in advance for help.

Best,
Laird

I've discovered the documentation flaws and have documented them in my answer on StackOverflow. I hope this helps others.
