Description Ed Santiago 2019-06-24 16:25:21 UTC

docker-1.13.1-99.gite467576.el7 has a regression:

  # docker run --name foo alpine touch /a
  # docker cp foo:a /tmp/b
  Error response from daemon: Rel: can't make /var/lib/docker/overlay2/ff010e78b2cddbbfe2e9768b43f7094f0b15322219bd061d3d39293e7e650279/merged/a relative to a

We may still want to hold on this one.  Just had a report that `docker cp testfile testctr:/tmp` is no longer copying the file to host (good), but is not copying it into the container either.  Investigating.

Comment 6 Tom Sweeney 2019-06-27 18:13:07 UTC

Steps that should work but are not at the moment.


    # docker run -t -i --name testctr --rm fedora bash

    //Inside the container:
    [root@ctrid /]# ln -s /tmp /test

    //Outside the container:
    # touch testfile; docker cp testfile testctr:/test

    //In the container,
    # ls /tmp

    // Outside the container,
    # ls /tmp

End result the file "testfile" is shown in the ls within the container, but NOT with the ls outside the container.  Currently it is not showing in either place.
