kafka连接从docker挂载在本地主机上的日志

我有kafka连接运行在正在生成日志到/ tmp目录中的文件的docker集装箱上。 在Docker的/tmp/kafka-connect.logs中生成的日志应该被挂载到本地的/tmp2/kafka-connect.logs目录。 当我挂载在/ tmp目录时 – docker run -p 8083:8083 -v /tmp/:/tmp/ -i jdbc但在/tmp2目录失败 – docker run -p 8083:8083 -v /tmp2/:/tmp/ -i jdbc 。 / tmp2目录的权限是777特权，并以root用户身份运行。

connect-log4j.properties

command to run docker image (container)

 docker run -p 8083:8083 -v /tmp2/:/tmp/ -i jdbc
