Panic: "no such file or directory" in Docker toolbox

General Discussions

Ok, I’m new and not sure where to head for this error. I checked this discussion, but it didn’t help much.

I’m using docker toolbox on Windows 8.1

I’m following this nice tutorial on how to make a container of a django webapp. Everything worked out almost until the end. I run the following:

docker run --publish=8001:8000 paolo/hello_django:latest

And this is what comes out:

panic: standard_init_linux.go:175: exec user process caused “no such file or directory” [recovered]
panic: standard_init_linux.go:175: exec user process caused “no such file or directory”

I can add also the useless inspect:

“State”: {
“Status”: “exited”,
“Running”: false,
“Paused”: false,
“Restarting”: false,
“OOMKilled”: false,
“Dead”: false,
“Pid”: 0,
“ExitCode”: 2,
“Error”: “”,
“StartedAt”: “2016-11-16T12:36:47.537758517Z”,
“FinishedAt”: “2016-11-16T12:36:47.575430686Z”
},

p.s is there a way to > log.txt the output of docker run? It works with docker inspect {Container_ID} > log.txt, but not with docker run. I had to select the txt from the bash.

suggest you can login the container and run the “paolo/hello_django:latest” manully .,maybe you can find why the servcie can’t start .

3

Not sure I understood what you mean. Ubuntu container seems to work. Not sure why django fail.

4

from the result of docker inspect , you can get the details of CMD

for example “CMD [“python”, “manage.py”, “runserver”, “0.0.0.0:8000”]”

use the command "docker exec -it container-id /bin/bash " to login the container ,and implement the script(manage.py) manully . you can check what issues happen when run the script .
but if you don’t have the skill for coding the script ,maybe it is difficult to find what happened.

Thanks for the patience. This does not look as anything good as CMD is null.

“Env”: [
“PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin”,
“DOCKYARD_SRC=hello_django”,
“DOCKYARD_SRVHOME=/srv”,
“DOCKYARD_SRVPROJ=/srv/hello_django”
],
“Cmd”: null,
“Image”: “paolo/hello_django:latest”,
“Volumes”: {
“/srv/logs/”: {},
“/srv/media/”: {}
},
“WorkingDir”: “/srv/hello_django”,
“Entrypoint”: [
“/docker-entrypoint.sh”
],

I suppose you’re telling me to run Ubuntu 14.04 container and then django from there. Am I right?

I ran

docker run -it Ubuntu:14:04

as well as

docker exec -it container-id /bin/bash/

Actually it is the same to run:

docker start -i container-id

The bash starts, but now I’m confused on what should I look for.

“Entrypoint”: [
"/docker-entrypoint.sh"
],

this shell ,it will Launch the django.you will find the details at the shell

No need to do that as I discovered it was a silly path error. I’m really a n00b.

Thanks for the header anyway.
