启动 opensearch 堆栈时出现问题（docker-撰写文件）

Question

我正在尝试使用来自 opensearch 网站的示例建立一个 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

        hard: 65536
    volumes:
      - opensearch-data2:/usr/share/opensearch/data
    networks:
      - opensearch-net
  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

volumes:
  opensearch-data1:
  opensearch-data2:

networks:
  opensearch-net:

但是 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之一检查日志，我得到“解析主机失败”，谁能指出我哪里出了问题？

打开搜索仪表板错误：

我在 mac 上遇到了同样的问题。但是当我增加 docker-desktop

中的内存大小时它得到解决
