I am creating a simple image with the following Dockerfile
FROM docker:latest
COPY docker-entrypoint.sh /usr/local/bin
ENTRYPOINT ['docker-entrypoint.sh']
Inside my container:
/ # ls -al $(which docker-entrypoint.sh)
-rwxrwxr-- 1 root root 476 Jul 26 07:30 /usr/local/bin/docker-entrypoint.sh
So the entrypoint file is both in the PATH
and executable;
But when running
docker run -v /var/run/docker.sock:/var/run/docker.sock -it imageinit
/bin/sh: [docker-entrypoint.sh]: not found
I am aware of this SO question, but this is about the problem of PATH
and file permissions (already addressed);
Interestingly your issues seems to be with the type of quotes you have chosen to use. If you change this line:
ENTRYPOINT ['docker-entrypoint.sh']
to
ENTRYPOINT ["docker-entrypoint.sh"]
then everything starts to work as expected.
If you check the documentation for the type of ENTRYPOINT
you are using all of the examples have double quotes.
I suspect what is happening when you use the single quotes is that docker is parsing this as the shell form of ENTRYPOINT
and trying to execute a script called [docker-entrypoint.sh]
which would explain the error message (as obviously no script of that name will exist).
