我正在尝试使用 ElasticSearch 后端在 docker 上运行 Apache Skywalking，但在让它保持正常运行和连接时遇到问题。

我根据他们的 github repo 使用了 docker compose 文件和环境变量值

      interval: 30s
      timeout: 10s

      retries: 3
      start_period: 40s
    environment:
      SW_STORAGE: elasticsearch
      SW_STORAGE_ES_CLUSTER_NODES: elasticsearch:9200
      SW_HEALTH_CHECKER: default
      SW_TELEMETRY: prometheus

    restart: always
    ports:

    environment:
      SW_OAP_ADDRESS: http://oap:12800

volumes:
  data:
    driver: local

然后使用这两个 env 值中的任何一个

ES_VERSION=6.8.8
SW_STORAGE=elasticsearch
IMAGE_TAG=es6
___
ES_VERSION=7.5.0
SW_STORAGE=elasticsearch7
IMAGE_TAG=es7

所有 3 个容器都出现了，我可以导航到 ElasticSearch 容器以及 SkyWalking UI 容器，但是在连接被拒绝和超时的日志中抛出了大量错误。

我确保它们都在同一个桥接 docker 网络上运行，以便您可以通过它们的名称访问容器。docker compose 定义创建了一个名为 skywalking_default 的网络

我看到的错误

在 OAP 容器上

我经常提到的主要问题之一是确保您正确定义了 SW_STORAGE，具体取决于您使用的是 ElasticSearch 6 还是 7，但我有

我正在运行 Docker 版本 20.10.6，在 MacOS 10.15.6 上构建 370c289

任何帮助将不胜感激谢谢
