Image Assembly Overview

The Env_and_Stacks/Projects/SoftwareComponentPipeline is designed to make it straightforward to automatically produce updated RPMs and RPM repositories from upstream components releases.

However:

• not all upstream applications (especially web applications) are amenable to being disassembled into component RPMs
• the high level "application glue code" that combines dependencies into a coherent application typically isn't designed for reuse
• packaging things as RPMs is very helpful for building Fedora itself, but markedly less so when building things to run *on* Fedora

These recommendations cover the available approaches to assembling individual components produced by the software component pipeline into larger binary images for easier consumption.

Base Container Images

Inputs: RPMs built in Koji Outputs: Docker container images Build system: Koji

Layered Container Images

Inputs: Source-to-image git repos, RPMs built in Koji (official images), RPMs built in COPR (unofficial images) Outputs: Docker container images Build system: Koji (official images), DOPR (unofficial images)

OSTree Images

Inputs: RPMs built in Koji Outputs: rpm-ostree trees Build system: Koji

Machine Images

Inputs: RPMs built in Koji, container images built in Koji Outputs: machine images (AMI, qcow2, etc) Build system: Koji

Live ISOs

Inputs: RPMs built in Koji, container images built in Koji Outputs: Live CD/DVD/USB images Build system: Koji

Installer ISOs

Inputs: RPMs built in Koji, container images built in Koji Outputs: Installer CD/DVD/USB images Build system: Koji
