docker - 无法从另一个 docker 容器中的传输客户端连接到 ElasticSearch docker 容器

Question

我使用以下方法启动了 elasticsearch docker 容器：

docker run -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" docker.elastic.co/elasticsearch/elasticsearch:6.2.4

然后我尝试链接另一个实际使用传输客户端（相同版本 - 6.2.4）的docker容器来访问elasticsearch容器，使用：

docker run -p 5000:5000 --link 57b2dc1f05b3:elasticsearch <container_name>

我收到以下错误消息：

node {#transport#-1}{zPkzTwpJRNmzGiEM8MOQQA}{elasticsearch}{172.17.0.2:9300} not part of the cluster Cluster [elasticsearch-cluster], ignoring...

此外，当我尝试从客户端 docker 容器的命令行连接时：

docker run -it --link 57b2dc1f05b3:elasticsearch <container_name> bash

在“elasticsearch:9200”上，与 elasticsearch docker 连接没有问题。

支持的代码片段：

val host = "elasticsearch"
val port = 9300
val clustername = "elasticsearch"
Settings settings = Settings.builder().put("cluster.name", clustername).build()
val client = new PreBuiltTransportClient(settings).addTransportAddress(new TransportAddress(InetAddress.getByName(host), port))
