Solution

  • This used to happen when TERM, HUP or KILL were sent while dcos_generate_config.sh executed docker load. The latest EA (1.7) ships with a trap on those signals which cleans up in this event.

    I'd suggest removing the dcos-genconf-$HASH.tar.xz which is written out to the directory in which you execute dcos_generate_config.sh, then re-running.

    This way you're assured to not have a corrupted tar file or image. The image is a tar file appended after the EOF inside the dcos_generate_config.sh, it extracts that file, writes it to disk and then docker loads it. There's a lot that can go wrong with that methodology.

    In line with removing that tar from disk I'd also recommend docker rmi on the image name if present before re-running.
