…ocker Adds a new side quest branching from Step 24 (Self-Hosted Runners) that covers Kubernetes-hosted runner fleets managed by Actions Runner Controller (ARC) and the runner.topology: arc-dind frontmatter field required for agentic workflows to run correctly on ARC's Docker-in-Docker mode.

Adds a new optional side quest, Running on Actions Runner Controller (ARC) with Docker-in-Docker, branching from Step 24: Run Your Agentic Workflow on a Self-Hosted Runner.
This node closes a gap for enterprise learners running Kubernetes-hosted runner fleets: it explains why agentic workflows require ARC's Docker-in-Docker (DinD) mode rather than Kubernetes mode, and walks through setting the
runner.topology: arc-dindfrontmatter field. The existing self-hosted runner content (Step 24 and its infrastructure deep-dive side quest) covers VM-based ephemeral/JIT runners and proxy configuration, but never addresses ARC/Kubernetes topology.Serves enterprise learners on Kubernetes infrastructure, chosen per the enterprise tie-break rule in the workshop guidelines.
