首先datax运行需要python2.x和jdk1.8
我这里在python2.7的镜像的基础上做
拉取python2.7的镜像到本地虚拟机
docker pull centos/python-27-centos7
上传jdk1.8 tar包已经datax安装包到本地服务器
在当前目录下编辑Dockerfile文件
FROM centos/python-27-centos7 #安装jdk ADD jdk-8u221-linux-x64.tar.gz /opt/local ENV JAVA_HOME /opt/local/jdk1.8.0_221 ENV PATH $JAVA_HOME/bin:$PATH # 添加并解压datax文件到/opt/local 目录 ADD datax.tar.gz /opt/local/ # 设置运行的工作目录，可不添加,运行中使用 docker -w 指定 WORKDIR /opt/local/datax ENTRYPOINT ["bash"]
通过docker build来生成镜像
sudo docker build -t="datax_python2" .
这个命令必须在Dockerfile文件所在的目录下运行
其中 -t表示给镜像起一个名字
查看本地的镜像，可以看到刚刚创建到的镜像
通过该镜像创建容器
docker run -t -i --name dataxpython2 datax_python2
检查python环境
检查jdk环境
用datax的自测脚本测试一下
python /opt/local/datax/bin/datax.py /opt/local/datax/job/job.json
(app-root)bash-4.2# python /opt/local/datax/bin/datax.py /opt/local/datax/job/job.json
