码头集装箱集群中的弹性搜索 [英] Elasticsearch in docker container cluster

问题描述

我想在2个不同的主机上运行2个ElasticSeach实例。我已经建立了基于Ubuntu 14.04和1.3.2版本的弹性搜索的自己的码头图像。如果我在1个主机上运行2个ES'容器，每个实例看到另一个主机，并且可以通信，但是当我在2个不同的主机上运行2个ES实例时，它没有工作。容器的9300端口绑定到9300主机的端口。

我的问题是：可以使用我的配置创建一个ES'集群？

最好的问候，
Lucas Rival

解决方案

我能够得到聚类在两个Docker主机上使用单播。我刚刚使用 ehazlett / elasticsearch 图像，但我不认为这应该是重要的。真正重要的一点似乎是将 network.publish_host 设置为公共或可路由的IP其Docker主机。

docker-host-01

  eth0：192.168.1.10 
 Docker版本1.4.1，build 5bc2ff8 / 1.4.1 
  

docker-host-02

  eth0：192.168.1.20 
 Docker版本1.4.1 ，构建5bc2ff8 / 1.4.1

Docker Host 01

  docker run -d \ 
 -p 9200：9200 \ 
 -p 9300：9300 \ 
 ehazlett / elasticsearch \ 
 --cluster.name = unicast \ 
  - 网络.publish_host = 192.168.1.10 \ 
 --discovery.zen.ping.multicast.enabled = false \ 
 --discovery.zen.ping.unicast.hosts = 192.168.1.20 \ 
 --discovery.zen.ping.timeout = 3s \ 
 --discovery.zen.minimum_master_n odes = 1 
  

Docker Host 02

  docker run -d \ 
 -p 9200：9200 \ 
 -p 9300：9300 \ 
 ehazlett / elasticsearch \ 
 --cluster.name = unicast \ 
 --network.publish_host = 192.168.1.20 \ 
 --discovery.zen.ping.multicast.enabled = false \ 
  - discovery.zen.ping.unicast.hosts = 192.168.1.10 \ 
 --discovery.zen.ping.timeout = 3s \ 
 --discovery.zen.minimum_master_nodes = 1 
  

I want to run 2 instance of ElasticSeach on 2 differents hosts. I have build my own docker image based on Ubuntu 14.04 and the 1.3.2 version of elasticsearch. If I run 2 ES' container on 1 host each instance see the other one and can communicate, but when I run 2 instance of ES on 2 differents host it's didn't work. The 9300 port of the container is bind to the 9300 host's port.

My question is : it's possible to create an ES' cluster with my configuration ?

Best regards, Lucas Rival

解决方案

I was able to get clustering working using unicast across two docker hosts. I just happen to be using the ehazlett/elasticsearch image, but I do not think this should matter all that much. The really important bit seems to be setting the network.publish_host setting to a public or routable IP its docker host.

  --discovery.zen.ping.unicast.hosts=192.168.1.20 \
  --discovery.zen.ping.timeout=3s \
  --discovery.zen.minimum_master_nodes=1

On Docker Host 02

docker run -d \
