Utilities for exporting backstage plugins as dynamic plugins for installation in Red Hat Developer Hub

Exports plugins as dynamic plugin archives. This should be run after the override-sources action in order to support per-plugin source overlays, or if patch modifications are needed.

Usage:

- name: Export Dynamic Plugins
  uses: ./export-dynamic
  with:
    plugins-root: plugins
    plugins-file: ${{ github.workspace }}/plugins-list.yaml
    destination: ${{ github.workspace }}/archives

Key Features:

• Exports plugins as dynamic plugin packages
• Handles both frontend and backend plugins
• Optional container image packaging

Applies patches and source overlays to modify plugin sources before export. This should be run before the export-dynamic action.

Features:

• Applies patches from <overlay-root>/patches/ directory using git apply
• Copies source overlay files from <overlay-root>/plugins/{plugin-name}/overlay/ directories
• Robust error handling and cleanup
• Ordered patch application (by filename)
• Configurable overlay subfolder name (defaults to "overlay")

Usage:

- name: Override Sources
  uses: ./override-sources
  with:
    overlay-root: ${{ github.workspace }}/my-overlay-repo
    workspace-root: .

Inputs:

• overlay-root: Absolute path to the overlay root directory (expects patches/ and plugins/ subdirectories)
• workspace-root: Directory to apply changes to (defaults to ".")
• source-overlay-folder-name: Name of subfolder within each plugin directory containing overlay files (defaults to "overlay")

Outputs:

• patches-applied: Number of patches applied
• source-overlay-applied: Whether source overlay files were copied
