Publishes the MIT operational metadata contract used by the Scaleway CLI and CD work in #2105 and DefangLabs/pulumi-defang#234. CD can publish physical resource identities and endpoints through a versioned defangDeployment output, and the CLI can discover them without importing provider implementation code or depending on child resource names.

Extracts four files unchanged from #2105: the standard-library-only metadata types/state reader and the Scaleway config-name helper, with tests. This lets the updated provider depend on current CLI APIs while the complete Scaleway CLI branch is reviewed separately. No module dependencies change.

Validation: make lint-fix, make lint (0 issues), and the full make test race/short suite passed with Go 1.26.10. Tests ran with ambient AWS region/workspace settings unset and Linux capabilities dropped so filesystem permission tests exercise ordinary user permissions.

Constitution: provider-independent metadata, no credentials in outputs, no resource creation, and no runtime plugin mechanism. Pulumi remains the resource source of truth.

The reader also handles Pulumi’s transient empty version-zero checkpoint during stack creation. The guard accepts only an explicit version zero, a nonempty stack name, and absent snapshot/export fields; malformed and unsupported state remains an error. The literal envelope was reproduced with Pulumi 3.268.0 and has regression coverage. Metadata fields and version 1 are unchanged.

CI at a841bfeb: Go, Nix, and CodeQL all passed. Paired live validation used CLI a58b5665 and provider/CD c5d9985 with image digest sha256:6eb5a16e2dbf149816a3e190a97e9e9f40d78ed9148b0002e28fee21c2e36ee1. The latest four shared files are byte-identical between this PR and #2105. Fresh-stack foreground completion, status, startup logs, native probes, and secret checks passed; independent cleanup confirmed zero native resources and a missing state bucket. The provider can retain its original published module pin because wire definitions and encoding are unchanged.

Error-classification test follow-up

Test-only commits CLI 0f8c754039335392a1fba088cbfc7d22f481fefc and shared contract 095b395689aa39da8ef5184b619fb8065dd9925f tighten expected failures to reject ErrNotFound for ambiguous deployments, future metadata versions, and malformed metadata. A malformed-metadata case and a non-string output skip case were added; existing bootstrap cases cover invalid JSON and unsupported state versions. Controlled mutations returning ErrNotFound for each of the three error paths fail the strengthened assertions. Both full race/short suites and lint pass. All checks pass on both test-only commits. CodeRabbit reviewed shared-contract 095b3956 with no actionable findings. Production files, dependencies, schema, and CD image are unchanged; the live-validated CLI artifact remains a58b5665 above.

Summary by CodeRabbit

  • New Features
    • Deployment state can now provide structured metadata, including deployment summaries and service details, when the state is supported and matches the selected provider, project, and stack.
    • Scaleway configuration names now consistently combine prefixes, projects, stacks, and keys, with slash characters normalized in the prefix.
  • Bug Fixes
    • Deployment metadata reads now distinguish missing metadata from malformed or unsupported state and avoid using incomplete or ambiguous entries.

📝 Walkthrough

The pull request adds Scaleway configuration-name helpers and a deployment metadata contract. It also adds JSON encoding and a reader that extracts matching metadata from Pulumi state. Tests cover naming, state selection, and bootstrap cases.

Changes: Scaleway Configuration Names

Layer / File(s) Summary
Configuration name helpers
src/pkg/clouds/scaleway/contract/config.go, src/pkg/clouds/scaleway/contract/config_test.go
ConfigPrefix joins and normalizes the prefix, project, and stack. ConfigName appends the key. Tests cover named prefixes, slash-containing stack names, and an empty prefix.

Deployment Metadata

Layer / File(s) Summary
Metadata contract and encoding
src/pkg/deployment/metadata.go
Adds metadata and service types, constants, ErrNotFound, and Metadata.Encode for JSON encoding.
Pulumi state discovery
src/pkg/deployment/metadata.go, src/pkg/deployment/metadata_test.go
ReadState filters Pulumi state resources and metadata, merges eligible service data, and handles missing, malformed, or conflicting candidates. Tests cover checkpoint and deployment snapshots, filtering, bootstrap inputs, and error cases.

Explanation

The title "feat(deployment): publish operational metadata contract" matches the main change. The PR adds the deployment metadata types, the ReadState reader that finds the defangDeployment output, and their tests. It also adds a Scaleway config-name helper, which the title does not mention. The title is specific and concise, and it follows a conventional commit format.

- Around line 37-41: Update the ReadState test cases and wantErr assertion so
expected failures must be non-ErrNotFound errors; add cases for invalid JSON,
unsupported state versions, and malformed metadata. Do not treat non-string,
non-secret outputs as errors, since ReadState skips them and may return
ErrNotFound.
