Simple Container-Utilizing Build Apparatus

SCUBA is a simple tool that makes it easier to use Docker containers in everyday development. It is intended to be used by developers in 'make' or 'scons' based build environments, where the entire build environment is encapsulated in a Docker container.

Its purpose is to lower the barrier to using Docker for everyday builds. SCUBA keeps you from having to remember a complex docker run command line, and turns this

$ docker run -it --rm -v $(pwd):/build:z -w /build -u $(id -u):$(id -g) gcc:5.1 make myprogram

into this:

$ scuba make myprogram

Scuba is hosted at PyPI.

To install:

$ sudo pip install scuba

To uninstall:

$ sudo pip uninstall scuba

Scuba can be built from source on Linux only (due to the fact that scubainit must be compiled):

1. Run make to build scubainit
2. Run ./run_nosetests.py to run the unit tests
3. Run sudo python setup.py install to install scuba
4. Run ./run_full_tests.py to test the installed version of scuba

If musl-libc is installed, it can be used to reduce the size of scubainit, by overriding the CC environment variable in step 1:

CC=/usr/local/musl/bin/musl-gcc make

Note that installing from source in this manner can lead to an installation with increased startup times for Scbua. See #71 for more details. This can be remedied by forcing a wheel to be installed, as such:

$ export CC=/usr/local/musl/bin/musl-gcc    # (optional)
$ sudo pip install wheel
$ python setup.py bdist_wheel
$ sudo pip install dist/scuba-<version>-py2.py3-none-any.whl

Configuration is done using a YAML file named .scuba.yml in the root directory of your project. It is expected that .scuba.yml be checked in to version control. Full documentation on .scuba.yml can be found in doc/yaml-reference.md, and specific examples can be found in the example directory.

An example .scuba.yml file might look like this:

image: gcc:5.1

aliases:
  build: make -j4

In this example, scuba build foo would execute make -j4 foo in a gcc:5.1 container.
