Creating an RPM from a Python package

On your dev host you need Python, virtualenv and Docker installed.

On your build host (or container) you need python and rpm-build packages.

Install cookiecutter Python package in your Python virtualenv. It can be used to create instalable Python packages. Most importantly, it creates the setup.py file for you.

$ virtualenv rpmbuild
$ source rpmbuild/bin/activate
$ pip install -U cookiecutter

Use a Github repo for the Python package cookiecutter.

$ cookiecutter gh:audreyr/cookiecutter-pypackage

$ cd example

Create the Dockerfile. Could be any Red Hat based distribution.

$ cat > Dockerfile << __EOF__
FROM fedora:latest
RUN dnf update -y && dnf clean all
RUN dnf install -y rpm-build && dnf clean all
RUN dnf install -y python && dnf clean all
ADD . /code
WORKDIR /code
RUN python setup.py bdist_rpm
WORKDIR /code/dist
CMD python -m SimpleHTTPServer
__EOF__

Start Docker, build an image from Dockerfile, build the RPM from Python package and expose port 8000.

$ sudo systemctl start docker
$ docker build -t rpm-build .
$ docker run -d -p 8000:8000 rpm-build

Go to http://localhost:8000/ in your browser and download the built RPM package.
