feat: GitOps XRD lifecycle demo, generate kyverno, and conversion metadata - #111
Merged
Conversation
…adata Add convctl generate kyverno, tighten convctl test to hub+spokes plus kind-filtered apps samples, always emit conversion metadata so Flux SSA prune succeeds, and ship the Flux/Argo GitOps demo with a standing migrate policy and --from-stage resume.

Otherwise, wait until the next included review is available. How can I continue?After more reviews become available, a review can be triggered using the To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews. How do review limits work?CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability. For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Kyverno 1.18.1 never runs MutatingPolicy mutateExisting, so the GitOps demo now writes each XR after the standing migrate policy lands. Also scope the demo-state umask and delete the Flux apps Kustomization on cleanup.

Inline comments:
In `@examples/crossplane-xr-multiversion/demo.sh`:
- Around line 58-120: Require and validate a non-option value before shifting
two arguments in the --demo-mode, --gitops-engine, --github-repo, --git-prefix,
--repo-visibility, and --from-stage branches. Reuse a shared need_value helper
near die, or equivalent existing validation, so missing values call die instead
of executing shift 2 and leaving the argument loop unchanged; preserve the
existing --create-repo handling.
- Around line 187-192: In the CLEANUP_ONLY branch, run gitops_cleanup_cluster
before cleanup_demo when GitOps is live, so Flux or Argo stops reconciling
before demo resources are deleted. Preserve gitops_cleanup_repo and the existing
conditional behavior, while ensuring cleanup_demo still runs for non-live
cleanup-only cases.
In `@examples/crossplane-xr-multiversion/gitops/lib.sh`:
- Around line 1022-1026: Update the Flux cleanup in the conditional block to
delete the `${GITOPS_APP_NAME}-apps` Kustomization alongside the existing
`${GITOPS_APP_NAME}` and `${GITOPS_APP_NAME}-conversion` resources before
deleting the flux-system namespace.
- Around line 533-547: Update gitops_install_argo to create the Argo repository
Secret with kubectl create secret generic and --from-literal arguments for the
repository fields, including the token, instead of interpolating them into YAML.
Quote the repo-${GITOPS_APP_NAME} argument in the preceding kubectl delete
command.
- Around line 386-398: Validate that the token returned by gh api in the runner
registration flow is non-empty before creating the runner-auth Secret. Fail
immediately with a clear error when the request fails or returns an empty token,
and prevent the subsequent Kubernetes resource creation from continuing; keep
the existing successful token path unchanged.
- Around line 186-191: Update gitops_set_push_url to stop embedding gh auth
token in the origin URL or persisting it in .git/config; configure and use
GitHub’s gh git credential helper for authenticated pushes while preserving the
repository’s origin remote URL.
- Around line 351-360: Update gitops_build_convctl_image to validate that
${REPO_ROOT}/bin/convctl exists before attempting the cp operation; when it is
missing, emit a clear error and return a failure status immediately so docker
build and subsequent steps do not run.
- Around line 918-949: In the fix-up and new-PR paths around
gitops_wait_pr_checks, remove the set +e/set -e toggles and capture or branch on
the command’s exit status directly. Preserve the existing rc-based failure
handling while ensuring gitops_ship does not leave errexit enabled for
subsequent stages.
In `@examples/crossplane-xr-multiversion/gitops/workflow/convctl.yaml`:
- Around line 65-117: Restrict the “Comment convctl output on the PR” step by
extending its if condition to require a same-repository pull request, such as
matching the head repository to the base repository, while preserving the
existing always() behavior. Keep convctl validation and job-log output unchanged
for fork-triggered pull requests.
In `@internal/cli/generate_kyverno.go`:
- Around line 295-317: Update migrateMatchCEL and/or migrateNeedsCEL so the
mutation predicate explicitly requires has(object.spec) and
has(object.spec.crossplane) before selecting the update path. Preserve the
existing oldObject/live and incoming/create logic while preventing selection
when the incoming object lacks spec.crossplane, allowing the fallback behavior
to handle that case safely.
In `@internal/cli/loader.go`:
- Around line 175-188: Update LoadSamples and the XRD/CRD test paths so
documents are decoded without requiring apiVersion, unrelated group/kind objects
are ignored, and matching objects missing apiVersion are rejected with the error
propagated through both paths; adjust filterSamplesByGVK or its callers to
perform target filtering before validation.
In `@internal/cli/test.go`:
- Around line 320-334: Update runTestCommon and testOneSample so sample-version
membership is checked against the unrestricted configured set, while targets
remains the --version-pair testing restriction. When a sample’s version is
configured but excluded by the selected target pair, skip it rather than
recording an error; retain errors only for versions absent from the configured
set.

- Line 201: Move the provisioning workflow currently implemented by the dev-up
target into an executable hack/dev-up.sh script, preserving its behavior and
DEV_MONITORING and DEV_KYVERNO configuration. Reduce dev-up to a thin target
that invokes the script while passing the DEV_* variables through, and ensure
the script enables appropriate shell error handling.

Reject missing two-token flag values so demo.sh cannot hang, keep the GitHub token out of the worktree remote URL, stop Flux/Argo before wiping objects, and keep --version-pair from failing still-configured samples. Unrelated YAML under --samples is ignored.
Capture gitops_wait_pr_checks without set +e/-e, and abort the demo if listing or annotating XRs fails so a migrate policy cannot be skipped.
