Question

我尝试以docker方式在google计算引擎的2个不同节点上运行elasticsearch集群。

使用1.7.1时，单播可以正常工作，但使用2.0.0时，它无法正常工作，2个节点无法连接在一起。

以下是Dockerfile，run command和elasticsearch.yml。感谢

Dockerfile

FROM java:8

#ENV ES_PKG_NAME elasticsearch-2.0.0
ENV ES_PKG_NAME elasticsearch-1.7.1

RUN \
  cd / && \
  #wget https://download.elasticsearch.org/elasticsearch/release/org/elasticsearch/distribution/tar/elasticsearch/2.0.0/$ES_PKG_NAME.tar.gz && \
  wget https://download.elasticsearch.org/elasticsearch/elasticsearch/$ES_PKG_NAME.tar.gz && \
  tar xvzf $ES_PKG_NAME.tar.gz && \
  rm -f $ES_PKG_NAME.tar.gz && \
  mv /$ES_PKG_NAME /elasticsearch

RUN mkdir -p /data/mnt
RUN chmod 777 -R /data/mnt
RUN chmod 777 -R /elasticsearch

RUN useradd -m docker && echo "docker:docker" | chpasswd && adduser docker sudo
USER docker

EXPOSE 9200
EXPOSE 9300

ADD elasticsearch.yml /elasticsearch/config/elasticsearch.yml

ENTRYPOINT ["/elasticsearch/bin/elasticsearch"]

运行命令

docker run -it -p 9200:9200 -p 9300:9300 \
    -v /data/elasticsearch:/data/mnt \
    -e ES_HEAP_SIZE=4g \

Answer 1

刚遇到完全相同的问题：启动docker容器时，必须更改变量 - network.publish_host ，因为它现在位于ES 2.0 network.host < / strong>：https://www.elastic.co/guide/en/elasticsearch/reference/current/setup-configuration.html#settings。

这应该可以做到！
