In docker I want to do this:
git clone XYZ
cd XYZ
make XYZ
However because there is no cd command, I have to pass in the full path everytime (make XYZ /fullpath). Any good solutions for this?

To change into another directory use WORKDIR. All the RUN, CMD and ENTRYPOINT commands after WORKDIR will be executed from that directory.
You can run a script, or a more complex parameter to the RUN. Here is an example from a Dockerfile I've downloaded to look at previously:
Because of the use of '&&', it will only get to the final 'pip install' command if all the previous commands have succeeded.
In fact, since every RUN creates a new commit & (currently) an AUFS layer, if you have too many commands in the Dockerfile, you will use up the limits, so merging the RUNs (when the file is stable) can be a very useful thing to do.
