Rocky Linux Package Builder

Containerized environment template for building Rocky Linux 9 RPM packages from source code. This project provides a reusable template for packaging any source distribution.

Project Structure

Sources are packaged in subdirectories.

rocky_pkg/
├── Containerfile          # Base Rocky Linux 9 build environment
├── <package_name>/
│   ├── Containerfile.<package_name>  # Package-specific dependencies
│   ├── Makefile           # Build automation
│   ├── <package_name>.spec  # RPM spec file
│   └── <source_tarball>   # Source distribution

Creating a New Package

1. Prepare Package Directory

Create a directory for your package. You may use the files used to package pnetcdf as a template:

mkdir <package_name>
cp pnetcdf/Makefile <package_name>/
cp pnetcdf/Containerfile.pnetcdf <package_name>/Containerfile.<package_name>

2. Build Process

1. Build the base image:

podman build -t rocky-pkg-builder .

2. Build package-specific image:

cd <package_name>
make image PACKAGE_NAME=<package_name>

3. Download source (if needed):

make source

4. Run interactive container:

make interactive

5. Build RPM (inside container):

make build

6. Copy RPMs to host:

make copy-rpms

3. Required Customizations

Containerfile.<package_name>

• Update package dependencies
• Install build tools specific to your package
• Configure environment variables

<package_name>.spec

• Create RPM spec file defining build process
• Set dependencies, file lists, and metadata
• Configure post-install scripts if needed

Makefile

• Update source download URLs
• Modify build targets as needed

Installation

Install built RPMs:

sudo dnf install <package_name>/RPMS/<package_name>-*.rpm

Container Architecture

• Base image: Rocky Linux 9 with development tools
• Builder user: Non-privileged build environment
• Volume mounting: Host directory mounted as /home/builder/artifacts
• Artifact extraction: RPMs copied to host via make copy-rpms

Example: PNetCDF Package

The pnetcdf/ directory serves as a complete example implementation demonstrating:

• MPI library integration (OpenMPI 4.1.1)
• Environment module configuration
• Fortran and C++ bindings
• Complex dependency management
