TL;DR

Adds a secret-safe BDD step for preparing explicit self-managed stack secrets
files and replaces the repeated copy plus base64-substitution sequences.

Additional Details

The new step keeps the template and destination visible in each feature. It
renders the exact $oauthtoken:<NGC_API_KEY> credential, writes the destination
with mode 0600, records it in the restoration ledger, and keeps raw or encoded
credentials out of command logs and failure messages.

The local and EKS NVCT task scenarios document their temporary runtime
dependencies. They remain expected failures until #1098 is resolved and the
corrected release from #1032 is consumed by the self-managed stack.

For the Reviewer

Review the domain boundary in tests/bdd/dsl/secrets.go and the ledger,
interpolation, permissions, and failure-hygiene coverage in the step tests.

Customer Release Notes

Not customer visible.

Plan Summary

Not applicable.

Usage

Feature files use:

And I prepare self-managed secrets file "<destination>" from template "<template>" using the current NGC registry credential

For QA

  • go test -short ./...
  • tests/bdd/scripts/lint.sh
  • Focused step and ledger tests cover 0600 permissions for absent and
    existing destinations before restoration, plus original-mode restoration.
  • Before the runtime work was split, the new secrets step ran successfully in
    the local single-cluster and multi-cluster Helmfile suites.
  • Current-main NVCT task scenarios are marked as expected failures until their
    two runtime dependencies land.
  • Live EKS validation remains tracked by BDD DSL: Validate second-wave changes on live EKS #1087.

Notes

The NVCT chart and Cassandra runtime fixes found during live validation were
removed from this PR and moved to separate PRs.

Summary by CodeRabbit

  • New Features
    • Added automated preparation of self-managed secrets files using the current registry credential.
    • Generated secrets files use Docker credential formatting and secure 0600 permissions.
  • Bug Fixes
    • Existing secrets files and permissions are restored after test scenarios.
    • Credential details are hidden from error messages and test logs.
  • Tests
    • Expanded coverage for credential rendering, file permissions, restoration, error handling, and multiple placeholders.
  • Documentation
    • Updated BDD guidance and scenario setup instructions for the new secrets workflow.

Replace copy-and-substitute sequences with a domain step that renders the exact NGC registry credential format. Preserve template permissions, snapshot destinations for teardown, and keep credential material out of logs and errors.

📝 Walkthrough

Walkthrough

The BDD DSL now renders self-managed secrets files with encoded NGC credentials. File steps snapshot and restore destinations. Feature scenarios use the new preparation step instead of manual copying and substitution.

Changes

BDD self-managed secrets

Layer / File(s) Summary
Secrets rendering contract
tests/bdd/dsl/secrets.go, tests/bdd/dsl/secrets_test.go, tests/bdd/PLAN.md, tests/bdd/AGENTS.md
Adds RenderSelfManagedSecrets with validation, placeholder replacement, Docker credential encoding, and credential-safe errors. Documentation defines the helper and restoration requirements.
Secrets preparation step wiring
tests/bdd/steps/file_steps.go, tests/bdd/steps/steps_test.go, tests/bdd/harness/ledger.go, tests/bdd/harness/ledger_test.go, tests/bdd/godog_test.go
Registers the new step, snapshots destinations, renders templates, creates directories, writes mode 0600 files, restores contents and permissions, and tests credential redaction and command logging behavior.
BDD feature migration
tests/bdd/features/*
Replaces repeated template-copy and credential-substitution steps across multi-cluster, observability, and single-cluster scenarios. Adds NVCT blocking comments to two scenarios.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to 0aca3

This localized BDD change prepares self-managed secret files with the described safety behavior, and no actionable merge-blocking risk remains after normal checks and review.

Keep the step handler as a delegation.

Move path resolution and Ledger orchestration into the invoked helper or a Suite operation. Keep iPrepareSelfManagedSecretsFile as a one- or two-line delegate.

As per coding guidelines, tests/bdd/steps/**/*.go says: Each handler is one or two lines plus a delegate to a dsl helper or Suite.Runner.

Addressed the handler-layering nitpick in 0aca36b: the registered Godog handler is now a one-line delegate, while the invoked helper owns interpolation, path resolution, ledger snapshotting, rendering, and the secure write. The focused tests, full short BDD suite, and lint pass.
