python-rpm-builder

Python to RPM Builder image

This image uses a patched version of virtualenv-tools in order to suport Python 3.x

Building your project

You will need a wrapper script, and a makefile, or just a script if you so choose. This is just how I prefer it.

$ cat package
#!/usr/bin/env sh

source /opt/rh/rh-python36/enable

make package

$ cat Makefile
NAME=my_cool_package
VERSION=$(shell cat VERSION)
WHEEL=$(shell echo dist/"${NAME}-${VERSION}"*.whl)

.PHONY: package clean

package: clean
    python setup.py bdist_wheel
    fpm \
        -s virtualenv \
        -t rpm \
        --name $(NAME) \
        -v $(VERSION) \
        --iteration release \
        --virtualenv-setup-install \
        --prefix /opt/$(NAME)/virtualenv \
        $(WHEEL)

clean:
    rm -rf *.egg-info build/ dist/ *.rpm

package_docker:
    docker run --rm -v $$(pwd):/src py2rpm ./package

The usage of the source line is to ensure that the relevant Python 3.6 configuration items, listed below, is included into the runtime before calling out to make to build your RPM.

sh-4.2# cat /opt/rh/rh-python36/enable
export PATH=/opt/rh/rh-python36/root/usr/bin${PATH:+:${PATH}}
export LD_LIBRARY_PATH=/opt/rh/rh-python36/root/usr/lib64${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}
export MANPATH=/opt/rh/rh-python36/root/usr/share/man:$MANPATH
export PKG_CONFIG_PATH=/opt/rh/rh-python36/root/usr/lib64/pkgconfig${PKG_CONFIG_PATH:+:${PKG_CONFIG_PATH}}
export XDG_DATA_DIRS="/opt/rh/rh-python36/root/usr/share:${XDG_DATA_DIRS:-/usr/local/share:/usr/share}"

When you're ready to go, you can simply run make package_docker and have it spin up docker, mount your source, and run the package command inside docker which will generate your RPM.
