无法通过运行 OpenSearch docker compose 来获取 OpenSearch 仪表板

Question

我是 Windows 用户。我安装了适用于 Linux 的 Windows 子系统 [wsl2]，然后使用它安装了 docker。然后我尝试开始使用 OpenSearch，因此我按照给定链接 https://opensearch.org/downloads.html中的文档进行操作并运行 docker-compose up，在 shell 中，我收到一条错误消息，例如

opensearch-仪表板 | {"type":"log","@timestamp":"2022-01-18T16:31:18Z","tags":["error","opensearch","data"],"pid":1, “消息”：“[ConnectionError]：getaddrinfo EAI_AGAIN opensearch-node1 opensearch-node1：9200”}

在端口 http://localhost:5601/ 我收到类似的消息

OpenSearch Dashboards 服务器尚未准备好

我还在 docker-desktop 中将内存的资源首选项更改为 5GB，但它仍然不起作用。有人可以帮我解决这个问题吗？

经过 5 天的 opensearch 问题后，我发现一些对我来说工作正常的东西：

• 将docker内存设置为4GB
• 和 docker vm.max_map_count = 262144

然后我使用以前版本的 opensearch，因为最新版本似乎不稳定：

• opensearchproject/opensearch:1.2.3
• opensearchproject/opensearch-dashboards:1.1.0
• opensearchproject/logstash-oss-with-opensearch-output-plugin:7.16.2

这是我的 docker-compose.yml 文件：
