git-build-rpm

Build RPMs from Git repositories.

Description

This project makes it easy to create RPMs from Git projects. Simply create an RPM Spec file with the same name as your Git repository in a directory named dist at the root of your project. This project is a good example: See dist/git-build-rpm.spec for an example. Then just run git-build-rpm to build your RPM:

git build-rpm

git-build-rpm will archive the current branch of your repository, as well as any submodules, and then call rpmbuild to build from the archive based on the spec file. Once the RPM has been built, it will be dropped in the root directory of your project, from where you can copy it to your RPM repository of choice.

Installation

Install dependencies via YUM:

sudo yum install git git-archive-all rpm-build \
                 'perl(Module::Build)' \
                 'perl(IPC::System::Simple)' \
                 'perl(Path::Class)'

Install dependencies via DNF and pip:

sudo dnf install git rpm-build perl-rpm-build-perl perl-IPC-System-Simple \
			perl-Path-Class perl-Test-Pod perl-Module-Build

sudo pip install --upgrade pip
sudo pip install git-archive-all

Build and install from Source:

perl Build.PL
./Build
sudo ./Build install

Build and install an RPM:

./bin/git-build-rpm
rpm -Uvh git-build-rpm*.rpm

Options

--spec-file: Path to RPM spec file.
--archive-ext: Extension used for creating archive
--git: Path to git program.
--git-branch: Git branch to build from.
-p --package-name: Name of the project, used to archive the repo.
-v --package-version: Version of the package, used in the RPM release name.
--dist: Name of distribution, used in RPM release name.
-D --define: Define macro=value.
--rpm-dir: Path to directory for building the RPM.
--quiet: Print as little as possible.
-V --version: Print the version number and exit.
-H --help: Print a usage statement and exit.
-M --man: Print the complete documentation and exit.

How it Works

Here's what git-build-rpm does when you run it:

Determines the current branch name via the --git-branch option, $GIT_BRANCH environment variable, or by parsing the output of branch -a --contains HEAD.
Determines the package name via the --package-name option or the output of git remote -v, preferring origin, and parsing it from the last part of the remote URL, ending in .git.
Determines the directory in which to build the RPM, using either the --rpm-dir option or a temporary directory that will be deleted on exit.
Determines the path to the RPM spec file, via the --spec-file option or by looking for a file named ./dist/$package_name.spec.
Unless specified via the --pakcage-version option, Extracts the version from the spec file. It tries using rpmspec, but if it's not available, it parses the version from the spec file directly. If that extracted version appears to be a macro, it will be run through rpm -E for evaluation.
Copies the spec file to the RPM build SPECS directory.
Archives the specified branch of the repository, as well as any submodules, into the RPM build SOURCES directory using supplied --archive-ext to determine archive type. Defaults to tar.gz.
Determines the RPM dist value via the --dist option, defaulting to the current epoch time and OS version. If the current branch is not "master", the branch name is also included in the dist value (with any invalid characters replaced with underscores). That is, the value is something like 1434755064.el7 when building master, and 1434755064.$branch_name_.el7 when building from any other branch.
Builds the RPM, setting dist and any other parameters passed via the --define option.
Moves all resulting RPMs to the current directory.
