Error: Cannot Start Container: stat /bin/sh: no such file or directory"

问题

I have been trying to create my own busybox base image.

# ./mkimage.sh -t pensu/busybox busybox-static
+ mkdir -p /var/tmp/docker-mkimage.US3tHy0uBQ/rootfs
+ tar --numeric-owner -caf /var/tmp/docker-mkimage.US3tHy0uBQ/rootfs.tar.xz -C /var/tmp/docker-mkimage.US3tHy0uBQ/rootfs '--transform=s,^./,,' .
+ cat > '/var/tmp/docker-mkimage.US3tHy0uBQ/Dockerfile'
+ rm -rf /var/tmp/docker-mkimage.US3tHy0uBQ/rootfs
+ docker build -t pensu/busybox /var/tmp/docker-mkimage.US3tHy0uBQ

+ rm -rf /var/tmp/docker-mkimage.US3tHy0uBQ

I can see the image is available with my docker repo.

# docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             VIRTUAL SIZE
pensu/busybox       latest              8eac78bfc9d6        7 seconds ago       2.476 MB

But when I try to do docker run, I always get the error:

# docker run -it pensu/busybox /bin/sh
exec: "/bin/sh": stat /bin/sh: no such file or directorytime="2015-04-09T16:03:45+05:30" level="fatal" msg="Error response from daemon: Cannot start container 8fe73b7832193c847d7975175a4be86d1f0b550b6a00b812bd4cdd18fe752468: exec: \"/bin/sh\": stat /bin/sh: no such file or directory"

I am not able to understand why is it giving that error? Am I doing something wrong? How else can I validate that I am creating a correct image that is in working condition?

回答1:

After you create image, check it with:

$ docker inspect $image_name

and check what you have in CMD option. For busy box it should be:

"Cmd": [
     "/bin/sh"
]

Maybe you are overwritting CMD option in your ./mkimage.sh

I hit this error ("stat /bin/bash: no such file or directory") when running the command:

docker exec -it 80372bc2c41e /bin/bash

The solution was to identify the kind of terminal (or shell) that is available on the container. To do so, I ran:

docker inspect 80372bc2c41e

In the output from that command, I saw:

"Cmd": [
    "/bin/sh",
    "-c",
    "gunicorn -b 0.0.0.0:7082 server.app:app"
],

This tells me that there's a /bin/sh command available, and I was able to connect with:

docker exec -it 80372bc2c41e /bin/sh

This error

docker: Error response from daemon: OCI runtime create failed: container_linux.go:348: starting container process caused "exec: \"/bin/sh\": stat /bin/sh: no such file or directory": unknown.

occurs when creating a docker image from base image eg. scratch. This is because the resulting image does not have a shell to execute the image. If your use:

ENV EXECUTABLE hello
cmd [$EXECUTABLE]

in your docker file, docker uses /bin/sh to parse the input string. and hence the error. Inspecting on the image, your will find:

$docker inspect <image-name>
"Entrypoint": [
                "/bin/sh",
                "-c",
                "[$HM_APP]"
            ]

This means that the ENTRYPOINT or CMD arguments will be parsed using /bin/sh -c. The solution that worked for me is to parse the command as a JSON array of string e.g.

cmd ["hello"]

and inspecting the image again:

"Entrypoint": [
                "hello"
            ]

This removes the dependence on /bin/sh the docker app can now execute the binary file. Example:

FROM scratch

# Environmental variables

# Copy files
ADD . /
# Home dir
WORKDIR /bin

EXPOSE 8083
ENTRYPOINT ["hospitalms"]

Hope this helps someone in future.

Explicitly mention the ubuntu version in the docker file which you are trying to RUN,

FROM ubuntu:14.04

Dont use like FROM ubuntu:Latest. This resolved my above "Cannot Start Container: stat /bin/sh: no such file or directory" issue

回答5:

You have no shell at /bin/sh? Have you tried docker run -it pensu/busybox /usr/bin/sh ?
