This sounds to me like a problem on the receiving end.  Are you able to 
successfully push this image (for example) to a test namespace on quay.io?
What registry server are you using?  How are you starting it?

If there's a "hard-way", I'm the first one to implement it.

 Hallo,
 
 When I try to push an image, created with buildah directly to docker,
 it aborts with following error:
 
    Error: pushing image "5d0da3dc9764" to "docker-daemon:test:2.0.0":
writing blob: io: read/write on closed pipe
 
 No errors are logged by dockerdaemon.
 
 When I check what happens with strace, I see that it aborts on epoll_ctl error:
 
    epoll_ctl(4, EPOLL_CTL_ADD, 7, {events=EPOLLIN|EPOLLOUT|EPOLLRDHUP|EPOLLET,
data={u32=4150263831, u64=9210128152865538071}}) = -1 EPERM
 
 7 is file descriptor which refers to some file under /var/lib/containers
(/var/lib/containers/storage/overlay-images/5d0da3dc976460b72c77d94c8a1ad043720b0416bfc16c52c45d4847e53fadb6/manifest)
 
 Is this supposed to work or do I misunderstand sthing?
 
 Best regards,
