Description Antonio Murdaca 2016-08-03 18:20:49 UTC

Description of problem:

oci-register-machine causes containers to fail with:

$ docker run -ti alpine bash
docker: Error response from daemon: oci runtime error: exit status 1:.

Instead:

$ docker run -ti alpine sh

The above works fine and here are containerd logs:

Version-Release number of selected component (if applicable):

docker-1.12.0-5.gitad4812e.fc26.x86_64

The above can be found in http://koji.fedoraproject.org/koji/taskinfo?taskID=15123002 if it's not already in Rawhide dnf

How reproducible:
always

Steps to Reproduce:
1. install docker-1.12.0-5.gitad4812e.fc26.x86_64
2. start docker
3. docker run -ti alpine bash (see failure)

spotted into https://bugzilla.redhat.com/show_bug.cgi?id=1362623#c8

Comment 2 Antonio Murdaca 2016-08-03 18:21:52 UTC

Of course, if I remove oci-register-machine from the hooks directory under /usr/libexec/oci/hooks.d/ everything works ok.

Comment 3 Daniel Walsh 2016-08-19 12:38:07 UTC

I removed oci-register-machine and I see the same.  alpine does not ship with bash

# docker run -ti alpine sh
/ # which bash
/ # bash
sh: bash: not found
