Walkthrough

The change reduces container build and runtime contents, installs Ruby dependencies explicitly at runtime, adds AsciiDoc conversion fixtures and tests, and validates conversion in the seven-phase Konflux integration pipeline.

Changes

AsciiDoc support

Layer / File(s) Summary
Container build and runtime updates
Containerfile, Containerfile-cuda
Builder inputs and packages are narrowed. Runtime Ruby installation uses explicit Gemfile inputs and conditional cachi2 environment loading. Runtime copies contain only required application files.
AsciiDoc conversion fixtures and tests
tests/asciidoc/*
Adds AsciiDoc and Markdown fixtures. Integration tests compare converted output with the reference and check required content markers.
Konflux conversion verification
tests/integration-konflux/pipeline-konflux.sh, .tekton/integration-tests/pipeline/rag-content-0-8-integration-test.yaml
Adds an initial AsciiDoc conversion validation phase, updates phase numbering, cleans temporary output, and installs diffutils in standard and GPU test environments.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🟡 Moderate · up to ac0ba

The PR can allow integration validation to proceed with no selected RAG content image when SNAPSHOT is omitted, weakening release checks, and the CUDA image build may fail because it still installs Ruby packages without the corresponding module setup. These bounded issues should be fixed or explicitly accepted before merge.

Update the skip reason message.

The skip reason says run 'bundle install' first, but the container now installs asciidoctor via gem install asciidoctor instead of Bundler. Update the message to reflect the current installation method.

Make SNAPSHOT valid by default or require it.

When SNAPSHOT is omitted, the default contains only rag-tool. The selectors require rag-content-cpu-0-8, rag-content-cuda-12-9-0-8, and lightspeed-stack-0-8, so the image results are empty. The matrix then passes an empty RAG_CONTENT_IMAGE. Remove the default or fail init-snapshot when required components are missing. Ensure external triggers provide a valid SNAPSHOT.

⚠️ Unverified finding
Sandbox verification was unavailable.

Remove the Ruby packages from the CUDA builder.

The builder no longer enables ruby:3.3 and no longer runs bundle install, but Line 14 still installs rubygems and rubygem-bundler. Red Hat documents Ruby 3.3 as an Application Stream and publishes the Bundler RPM as module content. RHEL 9 does not define default streams. This package transaction can fail before the runtime stage when the CUDA base image does not pre-enable a Ruby stream. (docs.redhat.com)

Remove these packages from the builder. Keep them in the runtime package transaction at Lines 74-79, where Bundler runs at Lines 96-99.

Proposed fix
 RUN ${BUILDER_DNF_COMMAND} install -y --nodocs --setopt=keepcache=0 --setopt=tsflags=nodocs \
     python3.12 python3.12-devel python3.12-pip \
-    skopeo \
-    rubygems rubygem-bundler && \
+    skopeo && \
     ${BUILDER_DNF_COMMAND} clean all

Verify the exact base image with dnf module list ruby and dnf repoquery before retaining these packages.


17-24: LGTM!
