Pre-build command

Sometimes a command needs to be run before running docker build, you can configure this in the pre build section.

There are two fields to pass for pre build. the first is path, which changes the working directory. To run the command in the root of the repo, just pass .. The second field is command, this is the shell command to be executed after the repo is cloned.

For example, say your repo had a folder in it called scripts with a shell script on-clone.sh. You would give path as scripts and command as sh on-clone.sh. Or you could make path just . and then the command would be sh scripts/on-clone.sh. Either way works fine.
