I would need more detail if possible:

  • output of docker info
  • output of docker-runc --version
  • what command where you running when it happened
  • more of the daemon logs

I've got this mystery as well, and very little relevant debugging experience (daemon logs?).

You should be able to get the docker daemon logs via: journalctl -u docker.service

If you could also specify which command resulted in this panic, it'll be helpful.

Thanks!

I'm able to get into the image if I override my ENTRYPOINT script. Here are the last several lines of output from the daemon logs:

I think the problem as I'm experiencing it may be related to Windows (CRLF) vs Linux (LF) line endings in my entrypoint script. Changing to Linux style (didn't mean to go to Windows at all) seems to have resolved my problem.

@mlaventure

Oh, I see.

It makes sense. Linux doesn't know how to take care of CRLF so it didn't find a binary called /bin/bash\r (which is correct).

This PR removed the panic.

@ironsmile

I am able to reproduce this without involving any fancy new line endings. This leads me to believe that the problem is general and is not limited to use case of @conversica-aaronpa.

I have a very simple script

$ cat test-ha
#!/bin/bash
echo HA

which has its executable flag set. Then the familiar panic happens when trying to execute it in a container:

$ docker run --rm -v "`pwd`:/opt" alpine:3.4 /opt/test-ha
panic: standard_init_linux.go:175: exec user process caused "no such file or directory" [recovered]

I am running this on OSX 10.11.6. I've also tested the same thing on docker 1.12.1 running on CentOS 7.2.1511 and the result is the same.

@ironsmile This is because alpine doesn't contain /bin/bash, and runc is panicing with the error that it couldn't find /bin/bash to execute.

The actual panic was removed in opencontainers/runc#1117 which now just returns an error instead of panicing.

I'm going to close this since it looks like a non-issue.

@mohit
use debian and ["array-format"] for entrypoint
4549c92 
* array format for ENTRYPOINT is required if using CMD arguments

* alpine is causing a container stack strace: based on
  moby/moby#27940 this would mean there is
  some alpine pkg I need installed but I don't know what

Which part of the system is depending on /bin/bash rather than /bin/sh?

My Go application was working in Alpine just fine, until today, when I see these weird error traces.

Update

Turns out I accidentally placed a GNU libc binary onto an Alpine (musl) image. Would have been nice to get a more direct error message when this happens.

@mcandre Nothing in docker relies on /bin/bash. It's wholly dependent on the image.
If you have a particular problem please open a new... or it might be better to discuss on slack first.
