docker-compose up throws Error

I followed the instructions on How to run local server, but when I run `docker-compose up` (as sudo) I get:
`ERROR: forbidden path outside the build context: ../compose/server/Dockerfile ()`

Changing line 22 from docker-compose.yml  from `../compose/server/Dockerfile` to `./compose/server/Dockerfile` does not solve the issue... 

Am I doing something wrong, or could someone please fix it?
