【问题描述】：
我正在尝试使用来自 opensearch 网站的示例来建立一个 opensearch 集群 https://opensearch.org/docs/latest/opensearch/install/docker/
version: '3'
services:
opensearch-node1:
image: opensearchproject/opensearch:1.2.3
container_name: opensearch-node1
environment:
- cluster.name=opensearch-cluster
- node.name=opensearch-node1
- discovery.seed_hosts=opensearch-node1,opensearch-node2
- cluster.initial_master_nodes=opensearch-node1,opensearch-node2
- bootstrap.memory_lock=true # along with the memlock settings below, disables swapping
- "OPENSEARCH_JAVA_OPTS=-Xms512m -Xmx512m" # minimum and maximum Java heap size, recommend setting both to 50% of system RAM
ulimits:
memlock:
soft: -1
hard: -1
nofile:
soft: 65536 # maximum number of open files for the OpenSearch user, set to at least 65536 on modern systems
hard: 65536
volumes:
- opensearch-data1:/usr/share/opensearch/data
ports:
- 9200:9200
- 9600:9600 # required for Performance Analyzer
networks:
- opensearch-net
opensearch-node2:
image: opensearchproject/opensearch:1.2.3
container_name: opensearch-node2
environment:
- cluster.name=opensearch-cluster
- node.name=opensearch-node2
- discovery.seed_hosts=opensearch-node1,opensearch-node2
- cluster.initial_master_nodes=opensearch-node1,opensearch-node2
- bootstrap.memory_lock=true

opensearch-dashboards:
image: opensearchproject/opensearch-dashboards:1.2.0
container_name: opensearch-dashboards
ports:
- 5601:5601
expose:
- "5601"
environment:
OPENSEARCH_HOSTS: '["https://opensearch-node1:9200","https://opensearch-node2:9200"]' # must be a string with no spaces when specified as an environment variable
networks:
- opensearch-net

opensearch-data2:
networks:
opensearch-net:
但 opensearch 仪表板无法启动并显示以下错误消息。如果我从打开的搜索节点检查日志，我得到“无法解析主机”，谁能指出我出了什么问题？
打开搜索仪表板错误：
