Building Package or Kernel Modules Using a Script

You can use a script to build a single Photon OS package without the need to setup a complete Photon build workspace. You just need a .spec specification file and the source files. You can place the source files and the specification files in the same folder, or provide a URL for the source file location, and then run the build_spec.sh script.

The script performs the following steps:

• Creates sandbox using docker
• Installs build tools and .spec build requirements from the Photon OS repository
• Runs rpmbuild

Result: You have a native Photon OS RPM package.

The build-spec.sh script is located in the photon/tools/scripts/ folder.

Prerequisites

Before you run the build-spec.sh script, perform the following steps:

• Ensure you have any Linux OS with a docker daemon running.
• Place the source and RPM .spec files in the same folder or provide a URL for the source files.

Procedure

Run the script. Provide the RPM .spec file name, including absolute or relative path, as an argument:

./photon/tools/scripts/build_spec.sh <path-to-rpm_spec_file.spec> [$STAGEDIR]

You can specify the staging directory ($STAGEDIR) where you want to store the generated RPM files and build logs. If you do not specify a staging directory, the generated output files are stored in the directory that contains the spec file.

The following topics show examples to build packages based on various use cases.
