Answer 1

It looks like your pipeline is trying to execute the file create_cities-controller.json.sh but you do not have permission to execute it. This could be for a variety of reasons. The most common two would be:

• the box that you are using has its "user" set to a user that does not have execute permission on that file. You can check the user using the docker inspect box:tag command (using the details of the box you used in your wercker.yml
• the file might not have its execute bit turned on - this can often happen when using git on windows for example - in this case you need to make sure you tell git to set the exec bit using this command: git update-index --chmod=+x ./create_cities-controller.json.sh (I am assuming this file comes from your source code repository - if not, then you would have to change it in the image itself, i.e. start a container from the image, do a chmod to fix it, then commit that container to update the docker image)
