Seatunnel Docker image镜像制作

#下载 seatunnel
- export version="2.3.3"
- wget "Index of /dist/seatunnel ${version}/apache-seatunnel-$ {version}-bin.tar.gz"
- tar -xzvf "apache-seatunnel-${version}-bin.tar.gz"
#解压
- tar -xzvf apache-seatunnel-${SEATUNNEL_VERSION}-bin.tar.gz
#配置connector, config/plugin_config 根据需要配置，Demo只需要以下两个即可
- --seatunnel-connectors--
- connector-fake
- connector-console
- --end--
#执行插件安装
- sh bin/install-plugin.sh 2.3.3
- #执行后，会自动下载maven包到 ~/.m2/wrapper/dists/apache-maven-3.8.4-bin/目录中
- #连接到 Central Repository:，下载传统比较慢
- #需要一下镜像，全用本地的setting.xml
  - #:~/.m2/wrapper/dists/apache-maven-3.8.4-bin/52ccbt68d252mdldqsfsn03jlf/apache-maven-3.8.4/conf#
- #再重新执行 sh bin/install-plugin.sh 2.3.3 使用国内镜像，例如：阿里云，此时就很快了
- #bin/install-plugin.sh 会将对就的jar包复制到 connectors/seatunnel和lib目录下
#修改apache-seatunnel-${version}-bin目录下的配置文件
- #编写plugin_config文件
  - vi config/plugin_config
    - --seatunnel-connectors--
    - connector-fake
    - connector-console
    - --end--
- #编写批处理配置文件
  - vi config/v2.batch.config.template

#下载openjdk:8镜像
- docker pull openjdk:8
#创建Dockerfile
- vi dockerfile-seatunnel-2.3.3

#使用JDBC模式，同步两个库的数据
- 修改plugin_config

- - - --seatunnel-connectors--
    - connector-fake

    - connector-jdbc
    - --end--
  - 安装插件，安装过程中会自动把相应的jar包复制到对应的目录中
    - sh bin/install-plugin.sh 2.3.3
  - 修改v2.streaming.conf.template配置

#配置MYSQL-CDC通过binlog实时数据同步

- MYSQL开启binlog
  - mysql的binlog开启方式,查看方式.三种binlog模式介绍.以及使用binlog恢复数据.删除binlog_mysql binlog 日志怎么打开-CSDN博客
- 开始CDC同步
  - 使用Apache SeaTunnel进行数据库同步（MySQL to MySQL）_seatunnel mysql-CSDN博客
  - Apache SeaTunnel 同步MySQL 数据到 Apache Kafka （SeaTunnel Engine）_seatunnel 从tcp到kafka-CSDN博客使用CDC同步到KAFKA
- 修改配置文件，与batch不同，是conf不是config
- vi v2.streaming.conf.template
- 内容如下
  
  env {
  # You can set SeaTunnel environment configuration here
  execution.parallelism = 1
  job.mode = "STREAMING"
  # 10秒检查一次，可以适当加大这个值
  checkpoint.interval = 10000
  #execution.checkpoint.interval = 10000
  #execution.checkpoint.data-uri = "hdfs://localhost:9000/checkpoint"

    # 源表，格式：数据库名.表名
    table-names = ["test.help_keyword_1"]
    base-url = "jdbc:mysql://mysql:3306/test"

- 临时启动容器
  - docker run --name seatunnel --hostname seatunnel-node1 --network my-net -e config="/data/seatunnel.streaming.conf" -v /mnt/sda1/seatunnel/apache-seatunnel-2.3.3/config/v2.streaming.conf.template:/data/seatunnel.streaming.conf -v /mnt/sda1/seatunnel/apache-seatunnel-2.3.3/config/plugin_config:/opt/seatunnel/plugin_config -v /mnt/sda1/seatunnel/apache-seatunnel-2.3.3/lib:/opt/seatunnel/lib -v /mnt/sda1/seatunnel/apache-seatunnel-2.3.3/plugins:/opt/seatunnel/plugins -v /mnt/sda1/seatunnel/apache-seatunnel-2.3.3/connectors/seatunnel:/opt/seatunnel/connectors/seatunnel -v /etc/localtime:/etc/localtime seatunnel:2.3.3
