Dockerfile.pybuild

#
# This will generate a local container with the specified version of Python.
#
# Note: This assumes the the tarball for the particular version you'd like to build has already been downloaded,
# unpacked, and patched appropriately.
#
# To build:
#   docker build --build-arg python_version=PYTHON-VERSION \
#                --build-arg install_target=INSTALL-TARGET \
#                -f Dockerfile.pybuild \
#                -t python:PYTHON-VERSION
#
#   PYTHON-VERSION  full version of Python to build (ex. 3.0.1)
#   INSTALL-TARGET  the target to make for installing (fullinstall for 3.0.1, install otherwise)
#
# Example for 3.0.1:
#   docker build --build-arg python_version=3.0.1 \
#                --build-arg install_target=fullinstall \
#                -f Dockerfile.pybuild \
#                -t python:3.0.1
