Fix docker compose wait-for-it.sh script

[stevesap]

Current status

The execution of the existing wait-for-it.sh script was reverted in #338 since it was not executing properly in windows.

Error message from docker-compose run create-bucket is:

No such file or directory

Expected Behavior

wait-for-it.sh should execute properly in linux, mac and windows environments

@AlexanderBarbie would you know how to fix this perhaps?

Well, that's why you don't develop software on Windows systems. 😄
On Windows you have to use path\to\wait-for-it instead of path/to/wait-for-it (unix), if you mount the volume. I will install a windows vm and try to fix it.

@pithumke can you please tell me which Docker version you are using and did you add the wait-for-it folder under Resources > File Sharing in the Docker settings?

And did you get the error

No such file or directory/bin/env: bash

This can be a problem with the line ending. Windows changes the line endings of downloaded files and then you can't start the bash script in a linux environment. I just checked out your commit #337 and had to change the line ending to unix line endings in my eclipse. Afterwards the error disappeared.

@AlexanderBarbie Thanks for picking this up! My versions are:

Docker version 19.03.8, build afacb8b
docker-compose version 1.25.4, build 8d51620a

I did not add the "wait-for-it" script to the Docker file sharing settings, as it is already being included as a volume mount:

volumes:
      - ./scripts/wait-for-it:/root/scripts/wait-for-it

The specific console output I got when running docker-compose run create-bucket (with the rest of the compose running in the background) was:

Starting cwa-server_objectstore_1 ... done
: No such file or directory

Upon playing around with the error and including some pwd and ls statements, I can positively say that the script exists inside the container and is being started, but still, the above error is being thrown. At this point I also suspect something along the lines of this or this, but unfortunately I currently don't have the time to look into this any further.
