standard_init_linux.go:190: exec user process caused "no such file or directory" - Docker

Use notepad++, go to edit -> EOL conversion -> change from CRLF to LF.

change entry point as below. It worked for me

ENTRYPOINT ["sh","/run.sh"]

As tuomastik pointed out in the comments, the docs require the first parameter to be the executable:

ENTRYPOINT has two forms:

ENTRYPOINT ["executable", "param1", "param2"] (exec form, preferred)

ENTRYPOINT command param1 param2 (shell form)

I had the same issue when using the alpine image.

My .sh file had the following first line:

#!/bin/bash

Alpine does not have bash. So changing the line to

#!/bin/sh

or installing bash with

apk add --no-cache bash

solved the issue for me.
