測試版本： mysql:5.7 ; es:5.6.4 ; elasticsearch-head:5 ;kibana:5.6.4 ;go-mysql-elasticsearch(mysql 資料自動同步到es的工具)

重要的事情說三遍：

• es 的東西，版本一點都不能差。
• es 的東西，版本一點都不能差。
• es 的東西，版本一點都不能差。

kibana版本對應上

docker search kibana:5.6.4 
這種方式一般就能找到版本

IK (es 的中文分詞，版本對應上)

　https://github.com/medcl/elasticsearch-analysis-ik

go-mysql-elasticsearch

　所支援的MySQL版本小於8.0. 所支援的ES版本小於6.0.mysqlbinlog的格式必須為row格式.

docker-compose file 構建如下（內部的XXX 替換成實際的值）：

相關配置檔案：

river.toml 配置見  https://github.com/go-mysql-org/go-mysql-elasticsearch/blob/master/etc/river.toml

ik：下載見 https://github.com/medcl/elasticsearch-analysis-ik

elasticsearch.yml:

cluster.name: "docker-cluster"
network.host: 0.0.0.0

# minimum_master_nodes need to be explicitly set when bound on a public IP
# set to 1 to allow single node clusters
# Details: https://github.com/elastic/elasticsearch/pull/17288
discovery.zen.minimum_master_nodes: 1
# 開啟前端訪問的跨域. (使用es-head 工具訪問的時候，前端有跨域問題，這裡允許跨域)
http.cors.enabled: true
http.cors.allow-origin: "*"

mysql5.7的Dockerfile:

FROM mysql:5.7

COPY mysqld.cnf /etc/mysql/mysql.conf.d/

mysqld.cnf檔案示例：

#
# The MySQL  Server configuration file.
#
# For explanations see
# http://dev.mysql.com/doc/mysql/en/server-system-variables.html

[mysqld]
pid-file	= /var/run/mysqld/mysqld.pid
socket		= /var/run/mysqld/mysqld.sock
datadir		= /var/lib/mysql
#log-error	= /var/log/mysql/error.log
# By default we only accept connections from localhost
#bind-address	= 127.0.0.1
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0

#以下是啟動log-bin的配置
log-bin = binlog
server-id=1
binlog-format = ROW
binlog_rows_query_log_events = off

　　寫在後面的話：

1、canal 等工具沒有go-mysql-elasticsearch 部署、配置簡單。

2、不要隨便嘗試build es，那可能會讓你鬱悶一天。退而求其次，使用-v 掛載吧

3、docker-compose 檔案書寫注意事項：

• 每個services 下面的key 名，隨便命名。
• container_name 隨便命名
• build 後面的值，寫含Docker file 的資料夾名。
• depends_on 寫services 下面的key 名。詳見docker-compose 檔案規範。
