"docker-entrypoint.sh": executable file not found in $PATH: unknown.

Issue:

• Currently the Dockerfile is not having the executable permission before marking the ENTRYPOINT with docker-entrypoint.sh script. As a result, the docker build is failing with the following error message:

  docker: Error response from daemon: failed to create task for container: failed to create shim task: OCI runtime create failed: runc create failed: unable to start container process: exec: "docker-entrypoint.sh": executable file not found in $PATH: unknown.
  

How to fix

• Either provide the executable permission to docker-entrypoint.sh manually before running the Dockerfile to build the container image.
• Or run the below command in the Dockerfile after doing the script copy as mentioned in https://github.com/docker-library/postgres/blob/master/15/alpine3.18/Dockerfile#L176C6-L176C42:

  RUN chmod +x  /usr/local/bin/docker-entrypoint.sh
  

Having the fix in the Dockerfile will be a better option so that if some one will do the copy paste of the docker file, still its going to work.

@yosifkit if the fix is already there, are you going to backport it ? Usually chmod 777 is not needed. Chmod 755 is also working.

Our stance is generally that if you want to build our images from source, you either need to use git clone to fetch them (which thus gets the appropriate permissions bits on docker-entrypoint.sh) or replicate what git clone would do yourself.
