使用主机网络的 Docker Swarm 上的 ElasticSearch

如何解决使用主机网络的 Docker Swarm 上的 ElasticSearch

我正在尝试使用 Azure 的 Ubuntu 映像 Docker Swarm 构建 3 个节点（1 个主节点 + 2 个节点）。 然后我尝试部署一个 ElasticSearch 3 节点集群。

这是我的 YAML 文件：

version: '3.7'
services:
  elasticsearch:
    image: docker.elastic.co/elasticsearch/elasticsearch:7.10.1
    hostname: "{{.Node.Hostname}}"
    environment:
      - node.name={{.Node.Hostname}}
      - cluster.name=rdcluster
      - "ES_JAVA_OPTS=-Xms2g -Xmx2g"
      - discovery.seed_hosts=elasticsearch
      - cluster.initial_master_nodes=Docker01,Docker02,Docker03
      - node.ml=false
      - xpack.ml.enabled=false
      - xpack.monitoring.enabled=false
      - xpack.security.enabled=false
      - xpack.watcher.enabled=false
      - bootstrap.memory_lock=false
    ulimits:
      memlock:
        soft: -1
        hard: -1
    volumes:
      - elasticsearch-data:/usr/share/elasticsearch/data
    deploy:
      mode: global
      endpoint_mode: dnsrr
      resources:
        limits:
          memory: 4G
    networks:
      - "myelasticnetwork"
  nginx:
    image: nginx:1.17.1-alpine
    ports:
      - 9200:9200
    deploy:
      mode: global
    command: |
      /bin/sh -c "echo '
      user nobody nogroup;
      worker_processes auto;
      events {
        worker_connections 1024;
      }
      http {
        client_max_body_size 4g;
        resolver 127.0.0.1 ipv6=off;
        server {
          listen *:9200;
          location / {
            proxy_set_header Connection keep-alive;
            set $$url http://elasticsearch:9200;
            proxy_pass $$url;
            proxy_set_header  Host $$http_host;
            proxy_set_header  X-Real-IP $$remote_addr;
            proxy_set_header  X-Forwarded-For $$proxy_add_x_forwarded_for;
          }
        }
      }' | tee /etc/nginx/nginx.conf && nginx -t && nginx -g 'daemon off;'"

volumes:
  elasticsearch-data:
  
networks:
   myelasticnetwork:
      external:
        name: "host"

似乎 Elastic 由于心跳而不断重新启动。 我认为问题在于在 Azure 中我们无法连接到不受 Azure 管理的“虚拟”网络。 在这种情况下，我的节点主机网络是 10.0.0.0/20。检查 ElasticSearch 网络我得到：

$ sudo docker network inspect elasticsearch_default

        },"Peers": [
            {
                "Name": "5341d18c2eb1","IP": "10.0.0.7"
            },{
                "Name": "c476ac76244e","IP": "10.0.0.16"
            },{
                "Name": "2ebc9eb2cd10","IP": "10.0.0.8"
            }
        ]
    }
]

底部 IP（10.0.0.7、10.0.0.8 和 10.0.0.16）与节点 IP 匹配。但是，顶级 IP (10.0.3.X) 是自动生成的，而不是 Azure。

有没有办法说我希望 9200 端口在节点 IP 上？ 我已经尝试使用 external.name = "host" 但我没有工作。

有人可以帮我吗？

谢谢
