- Apply stepTemplate defaults to steps (image, env, workingDir) - Handle task-level volumes with emptyDir support - Add variable substitution for workingDir - Override entrypoint for scripts to handle images with custom entrypoints - Create workingDir if it doesn't exist in container These fixes enable most example pipelines to run successfully with mallet: - steptemplate-pipelinerun: Now works with stepTemplate image/env - volumes-pipelinerun: Now correctly mounts emptyDir volumes - workspace-override-pipelinerun: Now substitutes workspace paths in workingDir Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
12/13 examples now passing with mallet: - Fixed stepTemplate, volumes, workingDir, and entrypoint issues - Sidecar networking is a known limitation (standalone containers) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Similar to Tekton, each task now runs in its own Podman pod: - All containers share network namespace (sidecars accessible via localhost) - Host aliases map sidecar names to 127.0.0.1 for DNS resolution - Steps run sequentially in the pod - Sidecars run alongside steps and are accessible by hostname Changes: - CreatePodWithOptions: Support host aliases for sidecar name resolution - CreateContainerInPod: Use pod field in JSON body instead of query param - RunContainerInPod: Full container lifecycle within a pod - executeTask: Refactored to use pods, start sidecars, run steps in pod All 13 example pipelines now pass, including sidecar-pipelinerun.
