Dockerfile - Mount host directory - copy a tar fie and run it - Error

Please find below the docker file contents -

FROM centostaryum
MAINTAINER karthik.jayaraman
VOLUME ["/DockerFiles/Tomcat/tar"]
ADD /tar/apache-tomcat-7.0.47.tar.gz /tmp
RUN ls /tmp
RUN tar -tzf /tmp/apache-tomcat-7.0.47.tar.gz -C /opt
EXPOSE  8080
CMD service tomcat7 start

It gives me the following error

The list command from the temp directory in the container lists the tomcat file but i am not sure what is wrong with the tar command.

I would appreciate some help in figuring out this issue. Thanks.

Per the documentation on the ADD command:

If is a local tar archive in a recognized compression format (identity, gzip, bzip2 or xz) then it is unpacked as a directory. Resources from remote URLs are not decompressed. When a directory is copied or unpacked, it has the same behavior as tar -x: the result is the union of:

  • whatever existed at the destination path and
  • the contents of the source tree, with conflicts resolved in favor of "2." on a file-by-file basis.

You can just ADD the file to /opt directly and it will do what you want. More explicitly, just do this:

ADD /tar/apache-tomcat-7.0.47.tar.gz /opt
