Setup script for reproducing
Description of problem:
When running a specific custom image (see attachement), docker fails to notice
when the single process exits. The container stays around, and attempts to
stop or remove it result in errors.
Doing the same with a slightly older version of docker shows expected behavior.
Version-Release number of selected component (if applicable):
docker-io-1.5.0-19.git5d7adce.fc22.x86_64
How reproducible:
Always.
Steps to Reproduce:
1. Run the attached SETUP script in an empty directory
2. Run the resulting image
# docker run --name=probe cp /bin/container-probe
3. After wrestling control back from the hanging "docker run",
try to stop or remove the container.
# docker stop probe
# docker rm -f probe
Actual results:
The expected output of container-probe is shown, but "docker run ..." does not
return to the command line prompt. In fact, job control doesn't work anymore
either (C-c, C-z, C-\).
Stopping and removing leads to these errors:
# docker stop probe
Error response from daemon: Cannot stop container probe: active container for
c492b7203b3d465c778935f97a12b3bf8a4c442731c7fd25cee6f50798ac4f65 does not exist
FATA[0000] Error: failed to stop one or more containers
# docker rm -f probe
Error response from daemon: Could not kill running container, cannot remove -
active container for
c492b7203b3d465c778935f97a12b3bf8a4c442731c7fd25cee6f50798ac4f65 does not exist
FATA[0000] Error: failed to remove one or more containers
Expected results:
The output is shown and "docker run" terminates successfully, the container is
show as "exited" and can be removed.
Additional info:
docker-io-1.5.0-1.fc21.x86_64 shows the expected behavior.
"docker run -i" return control to the shell, but the resulting container can't
be stopped or removed either.
"systemctl restart docker" puts the "probe" container into a state where it can
be removed.
