一、制作docker镜像：
Dockerfile文件：
FROM alpine:latest MAINTAINER chengcuichao RUN apk update && apk add openjdk8 shadow sudo RUN wget https://download.elastic.co/elasticsearch/release/org/elasticsearch/distribution/tar/elasticsearch/2.4.6/elasticsearch-2.4.6.tar.gz RUN tar zxvf elasticsearch-2.4.6.tar.gz -C /usr/local/ && rm -f elasticsearch-2.4.6.tar.gz && /usr/local/elasticsearch-2.4.6/bin/plugin install mobz/elasticsearch-head RUN useradd elastic && chown -R elastic:elastic /usr/local/elasticsearch-2.4.6 COPY ./run.sh /root/ RUN chmod +x /root/run.sh CMD /root/run.sh
run.sh文件：
#!/bin/sh sed -i "s/node.name: node-1/node.name: $HOSTNAME/g" /usr/local/elasticsearch-2.4.6/config/elasticsearch.yml sudo -H -u elastic sh /usr/local/elasticsearch-2.4.6/bin/elasticsearch
上传镜像：
docker build -t elastic:2.4 docker tag elastic:1 192.168.78.4/es/elasticsearch:2.4.6 docker push 192.168.78.4/es/elasticsearch:2.4.6
二、在kubernetes上创建：
创建配置文件：
# ======================== Elasticsearch Configuration ========================= # # NOTE: Elasticsearch comes with reasonable defaults for most settings. # Before you set out to tweak and tune the configuration, make sure you # understand what are you trying to accomplish and the consequences. # # The primary way of configuring a node is via this file. This template lists # the most important settings you may want to configure for a production cluster. # # Please see the documentation for further information on configuration options: # <http://www.elastic.co/guide/en/elasticsearch/reference/current/setup-configuration.html> # # ---------------------------------- Cluster ----------------------------------- # # Use a descriptive name for your cluster: # cluster.name: my-application # # ------------------------------------ Node ------------------------------------ # # Use a descriptive name for the node: # node.name: node-1 # # Add custom attributes to the node: # # node.rack: r1 # # ----------------------------------- Paths ------------------------------------ # # Path to directory where to store the data (separate multiple locations by comma): # # path.data: /path/to/data # # Path to log files: # # path.logs: /path/to/logs # # ----------------------------------- Memory ----------------------------------- # # Lock the memory on startup: # # bootstrap.memory_lock: true # # Make sure that the `ES_HEAP_SIZE` environment variable is set to about half the memory # available on the system and that the owner of the process is allowed to use this limit. # # Elasticsearch performs poorly when the system is swapping the memory. # # ---------------------------------- Network ----------------------------------- # # Set the bind address to a specific IP (IPv4 or IPv6): # network.host: 0.0.0.0 # # Set a custom port for HTTP: # http.port: 9200 # # For more information, see the documentation at: # <http://www.elastic.co/guide/en/elasticsearch/reference/current/modules-network.html> # # --------------------------------- Discovery ---------------------------------- # # Pass an initial list of hosts to perform discovery when new node is started: # The default list of hosts is ["127.0.0.1", "[::1]"] # discovery.zen.ping.unicast.hosts: ["es-service"] # # Prevent the "split brain" by configuring the majority of nodes (total number of nodes / 2 + 1): # discovery.zen.minimum_master_nodes: 2 # # For more information, see the documentation at: # <http://www.elastic.co/guide/en/elasticsearch/reference/current/modules-discovery.html> # # ---------------------------------- Gateway ----------------------------------- # # Block initial recovery after a full cluster restart until N nodes are started: # # gateway.recover_after_nodes: 3 # # For more information, see the documentation at: # <http://www.elastic.co/guide/en/elasticsearch/reference/current/modules-gateway.html> # # ---------------------------------- Various ----------------------------------- # # Disable starting multiple nodes on a single system: # # node.max_local_storage_nodes: 1 # # Require explicit names when deleting indices: # # action.destructive_requires_name: true
