standard_init_linux.go:178: exec user process caused "exec format error"

docker started throwing this error:

standard_init_linux.go:178: exec user process caused "exec format error"

whenever I run a specific docker container with CMD or ENTRYPOINT, with no regard to any changes to the file other then removing CMD or ENTRYPOINT. here is the docker file I have been working with which worked perfectly until about an hour ago:

I forgot to put

#!/bin/bash

at the top of the sh file, problem solved.


Add this code

   #!/usr/bin/env bash

at the top of your scirpt file.


Another possible reason for this could be if the file is saved with Windows line endings (CRLF). Save it with Unix line endings (LF) and the file will be found.


I have faced same issue in RHEL 7.3, docker 17.05-ce when running offline loaded image. It appeared the default storage driver of RHEL/CentOS changed from device-mapper to overlay. Reverting back the driver to devicemapper fixed the problem.

dockerd --storage-driver=devicemapper

or

/etc/docker/daemon.json
{
  "storage-driver": "devicemapper"
}

Extending to the accepted answer:

For an alpine (without bash) image:

#!/bin/ash

at the top of the sh file, solves the problem.


One more possibility is that #!/bin/bash is not in the very first line. There must be really nothing before it (no empty lines, nothing).


Not a direct answer to the question asked. Although I got the error while calling "docker-compose up" to bring my nodejs application up. Realized that in my "Dockerfile" i had CMD ["./server.js"].

To fix i replaced it with CMD ["npm","start"] and that solved the issue. Hope if someone lands here for this exception may find this useful.
