Summary

  • add an Azure DevOps target for Crossplane XRD-generated scaffolder templates
  • parse the RepoUrlPicker Azure DevOps URL at template runtime
  • push the generated manifest to a new branch with azure:repository:push, then create a PR with azure:pr:create
  • document the two required backend modules and cover the generated flow with unit tests

Problem

publishPhase.target: azure was not handled by the Kubernetes ingestor. It fell through to publish:github:pull-request, which cannot publish to a dev.azure.com repository.

Notes

The generated flow intentionally opens a pull request; it does not write directly to the default branch. The target requires the host app to register @backstage-community/plugin-scaffolder-backend-module-azure-devops for the azure:repository:push and azure:pr:create actions, plus the TeraSky utilities module added here.

Test plan

  • Added unit coverage for Azure RepoUrlPicker parsing.
  • Added unit coverage that an Azure XRD template generates parse, push, and PR actions.
  • yarn install --immutable could not complete locally because the repository's existing isolated-vm native dependency failed to build on the local Node 26 runtime; tests could not be executed.

Review Change Stack

📝 Walkthrough

Walkthrough

The PR adds an Azure DevOps repository-details scaffolder action, workspace path handling, existing kustomization.yaml merging, and Azure XRD publishing support.

Changes

Azure DevOps publishing

Layer / File(s) Summary
Azure DevOps repository action
plugins/scaffolder-backend-module-terasky-utils/src/actions/azure-devops-repository.ts, plugins/scaffolder-backend-module-terasky-utils/src/actions/azure-devops-repository.test.ts, plugins/scaffolder-backend-module-terasky-utils/src/module.ts
The module registers a repository-details action. The action validates Azure DevOps URLs and returns repository values with an encoded remote URL. Tests cover valid and invalid inputs.
Workspace path templating
plugins/scaffolder-backend-module-terasky-utils/src/actions/claim-templating.ts, plugins/scaffolder-backend-module-terasky-utils/src/actions/claim-templating.test.ts
The claim templating action accepts xrdPathInWorkspace. When enabled, it resolves xrdPathTemplate into the workspace base path. It also merges resources from an existing workspace kustomization.yaml. Tests cover both behaviors.
XRD Azure publishing flow
plugins/kubernetes-ingestor/src/providers/EntityProvider.ts, plugins/kubernetes-ingestor/src/providers/EntityProvider.test.ts, plugins/kubernetes-ingestor/config.d.ts
Azure publishing clones the target branch before manifest generation, applies target paths through workspace templating, pushes a manifest branch, and creates a pull request. Tests cover workflow order, branch values, repository selection, target paths, and pull-request links. Configuration documents the supported targets and package requirements.

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

Merge Risk: 🔵 Low · up to 551c7

The Azure publishing flow can incorrectly restore resources when a cloned kustomization.yaml intentionally contains an empty resources list, potentially generating a pull request that reintroduces manifests the user removed; the change is otherwise mergeable with explicit owner follow-up.

Pull request overview

This PR adds first-class Azure DevOps support to the Kubernetes ingestor’s Crossplane XRD-generated scaffolder templates by generating an Azure-specific publish flow (parse RepoUrlPicker input → push branch → open PR). It also introduces a small utility scaffolder action in the TeraSky utils backend module to parse Backstage’s Azure RepoUrlPicker value into the discrete fields required by Azure DevOps scaffolder actions, with accompanying unit tests.

Changes:

  • Add terasky:azure-devops:repository-details scaffolder action (and registration) to parse Azure RepoUrlPicker values and emit organization, project, repository, and remoteUrl.
  • Update XRDTemplateEntityProvider to generate Azure DevOps publish steps using azure:repository:push followed by azure:pr:create.
  • Add unit coverage for RepoUrlPicker parsing and for Azure publish-step generation.

Pushed 1d3f67d. The targetPath review comment was correct, and chasing it surfaced a second bug in the same flow.

azure:repository:push takes only sourcePath, and it runs addFiles + commitAndPushBranch against that directory — it commits an existing working copy rather than publishing the workspace the way publish:github:pull-request does. So the previous revision had two problems: injecting targetPath was a no-op, and there was no repository in the workspace to commit in the first place.

The Azure sequence is now:

  1. terasky:azure-devops:repository-details
  2. azure:repository:clone — clones the target branch into the workspace root, before manifest generation so the directory is still empty
  3. terasky:claim-template
  4. azure:repository:push
  5. azure:pr:create

For the terasky.backstage.io/target-path annotation, terasky:claim-template gains an xrdPathInWorkspace input. When set it resolves the path template on disk instead of writing to the workspace root, so the manifest lands at its repository path inside the clone. The ingestor sets it only for Azure targets; every other target keeps the existing workspace-root plus targetPath behaviour, and targetPath is no longer emitted onto Azure steps where it would be ignored.

Tests: 147 in EntityProvider.test.ts and 37 in the terasky-utils action suites, including a new case asserting the manifest path resolves to presets/eu-west-1/my-db/my-db.yaml under xrdPathInWorkspace, and one asserting no step emits targetPath for Azure.

Pushed 551c705 for the kustomization.yaml finding, which was a real data-loss bug introduced by the clone step.

The existing-resource lookup reads owner/repo out of the repoUrl query string and calls the GitHub contents API. An Azure DevOps RepoUrlPicker value carries organization/project/repo instead, so owner was null, existingResources stayed empty, and the action rewrote the cloned kustomization.yaml with only the new entry — discarding everything already listed in the repository.

The action now reads kustomization.yaml from the workspace first and merges into it, falling back to the remote lookup only when nothing is on disk. That is the correct precedence for any clone-based flow: the working copy is authoritative and already at the right ref. Targets that do not clone are unaffected, since the file is not present in their workspace.

Added a regression test that seeds a cloned kustomization.yaml containing already-in-repo.yaml, and asserts both entries survive and that no remote fetch is attempted.

Two Copilot comments are still showing against the head commit but were resolved earlier:

  • getPullRequestUrl() having no azure case — added in ff4f5ac, it now builds <remoteUrl>/pullrequest/<pullRequestId>.
  • targetPath not being injected for Azure — now deliberate, per the azure:repository:push contract. The annotation is applied through xrdPathInWorkspace in 1d3f67d instead.

…e annotated repo path for Azure DevOps

azure:repository:push stages and commits an existing working copy, so the
publish sequence needs azure:repository:clone ahead of manifest generation.
It also accepts only sourcePath, so the terasky.backstage.io/target-path
annotation cannot be applied via targetPath as it is for the other targets.

terasky:claim-template gains xrdPathInWorkspace, which resolves the path
template on disk instead of writing to the workspace root, and the ingestor
sets it for Azure targets and no longer emits an ignored targetPath.

…the remote lookup

The existing-resource lookup only speaks the GitHub contents API, so a publish
flow that clones the repository into the workspace first — Azure DevOps — found
no existing resources and rewrote kustomization.yaml with only the new entry,
dropping everything already listed in the repository.
