【问题标题】：Trying to setup elasticsearch cluster with docker-compose尝试使用 docker-compose 设置弹性搜索集群

【问题描述】：

我的环境是两台物理机，都运行在 docker-compose 中。

我想创建跨两个 docker 容器的 elasticsearch 集群。

两个容器不能相互连接，有什么想法吗？

docker 镜像正在使用 elasticsearch:5.4.2

docker-compose.yml

version: '2'

services:
  elasticsearch:
    image: es:542
    hostname: es2
    container_name: es2
    user: elasticsearch
    ports:
    - 9200:9200
    - 9300:9300
    environment:
    - ES_JAVA_OPTS=-Xms1g -Xmx1g
    command: /usr/share/elasticsearch/bin/elasticsearch

elasticsearch.yml

http.host: 0.0.0.0
transport.host: 0.0.0.0
discovery.zen.minimum_master_nodes: 2

cluster.name: prod_es_cluster
node.name: prod_es_node1
node.master: true
node.data: true
discovery.zen.ping_timeout: 10s

network.host: 0.0.0.0
network.bind_host: 0.0.0.0
network.publish_host: 0.0.0.0
transport.tcp.port: 9300
discovery.zen.ping.unicast.hosts: ["127.0.0.1", "[::1]"]

【解决方案1】：

现在我使用openvswitch 和pipework 构建集群网络

ovs 设置：

#ES1
sudo brctl addbr br0
sudo ip link set dev br0 up
sudo ovs-vsctl add-br ovs0
sudo ovs-vsctl set bridge ovs0 stp_enable=true
sudo ovs-vsctl add-port ovs0 br0
sudo ovs-vsctl add-port ovs0 gre0 -- set interface gre0 type=gre options:remote_ip=10.251.34.50

管道设置：

sudo pipework-master/pipework br0 -i eth1 es1 172.28.0.2/8

docker 容器网络信息：

elasticsearch@es1:/usr/share/elasticsearch$ ip a

521: eth1@if522: mtu 1500 qdisc pfifo_fast state UP group default qlen 1000 链接/以太 4e:06:91:91:1f:3e brd ff:ff:ff:ff:ff:ff inet 172.28.0.2/8 brd 172.255.255.255 范围全局 eth1 valid_lft 永远首选_lft 永远

设置两个 docker 容器后，集群应该可以工作了！
