1、编译代码修改配置

按照 交易部署说明（链接https://webasedoc.readthedocs.io/zh_CN/latest/docs/WeBASE-Transaction/install.html）完成到第4步，主要需要修改的是“#连接节点的ip和channelPort” 和 “配置数据库连接信息” 这两个配置。

2、创建镜像

复制Dockerfile文件到编译后生成的dist目录中，执行：（注意最后有个点）

docker build -f Dockerfile -t webase-trans:v1.4.1 .

执行结果：

查看生成的镜像：

docker images

REPOSITORY                                                  TAG       IMAGE ID       CREATED              SIZE

3、运行镜像到容器

docker run -d --name WeBASE-Trans -v /docker_file/trans/WeBASE-Transaction/dist/log:/dist/log -p 5003:5003 webase-trans:v1.4.1

其中参数“-v /docker_file/trans/WeBASE-Transaction/dist/log:/dist/log”把日志挂载出来，（冒号前面的参数是宿主机的绝对路径），方便查看输出日志：

tail -f log/transaction.log

[main] INFO  Application() - main run success...
