Description

Add Fern scaffolding to enable a published documentation site at docs.nvidia.com/nodewright.

Fixes #484

Rebased onto main after #486 merged the docs restructure (superseding #483). This PR now contains only the Fern scaffold — no restructure commits.

What's included

fern/ directory:

  • fern.config.json — NVIDIA org, "latest" CLI version
  • docs.yml — NVIDIA global theme, docs.nvidia.com/nodewright custom domain, multi-source: true
  • .gitignore — excludes .fern/ and node_modules/

docs/index.yml navigation:

Section Pages
Getting Started Overview, Installation, Migration
Architecture Operator Status, Interrupt Flow, Ordering
User Guide CLI, Deployment Policy, Secrets, Runtime Required, Taints, Uninstall
Operations K8s Support, Resource Management, Resources at Scale, Versioning
Observability Metrics
Security Kyverno Policies

contributing/ and designs/ intentionally excluded from published navigation.

docs/getting-started/ content:

  • overview.md — real content extracted from README (what/why/benefits/features)
  • installation.md — real content extracted from README (prerequisites, helm install, verify, uninstall)

These replace the thin link-only pages from the restructure, since Fern cannot render files outside docs/.

CI workflows (4):

  • fern-docs-ci.ymlfern check, fern docs md check, MDX safety, fern docs broken-links on PRs
  • fern-docs-preview-build.yml — artifact collection (secrets-free, fork-safe)
  • fern-docs-preview-comment.yml — preview URL + stable :herb: PR comment with page links
  • publish-fern-docs.yml — publish on docs/v* tags with git archive version freezing, version stamping, tee output capture

Prerequisites before merge

  • DOCS_FERN_TOKEN org secret provisioned for preview + publish workflows

Review Change Stack

📝 Walkthrough

Walkthrough

Adds Fern documentation scaffolding for NodeWright. The change defines site configuration, navigation, branding, and expanded getting-started content. It adds pull-request validation, preview build and comment workflows, and release publishing for version tags or manual dispatch. It also adds ignore rules for Fern-generated files and dependencies.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟠 High · up to b275c

The PR adds documentation publishing and preview workflows with unresolved security and release-correctness risks, including unsafe release metadata handling, privileged pull-request updates, mutable dependencies, and publication/versioning failure modes; the installation guide also needs corrected Helm and private-registry instructions, so merge should wait for these issues to be fixed or explicitly accepted.

Inline comments:
In @.github/workflows/fern-docs-ci.yml:
- Around line 16-19: Add workflow-level concurrency settings for the checks
workflow, using a pull-request number or ref as the group key and enabling
cancel-in-progress so superseded runs are canceled.
- Around line 29-36: Update the Install Fern CLI step to use an exact reviewed
fern-api version instead of accepting latest from fern/fern.config.json, and
install it reproducibly with an integrity or lockfile-based pin. Remove or
revise the current latest/semver validation so the workflow cannot resolve a
moving npm release.
- Around line 21-25: Update the workflow steps using actions/checkout and
actions/setup-node to immutable commit-SHA references instead of mutable tags,
and configure checkout to disable persisted credentials. Preserve the existing
checkout and Node.js setup behavior while applying these hardening changes.

In @.github/workflows/fern-docs-preview-build.yml:
- Line 43: Update the changed-page metadata command in the workflow to include
both .md and .mdx files in its git diff pathspec, so changed MDX pages are
recorded alongside Markdown pages.
- Line 30: Pin the four external action references to immutable full commit SHAs
instead of mutable tags, retaining each action version in a comment: update
.github/workflows/fern-docs-preview-build.yml lines 30 and 46, and
.github/workflows/fern-docs-preview-comment.yml lines 31 and 44. No other
workflow behavior should change.

Apply the same fix in @.github/workflows/publish-fern-docs.yml at line 32: The
publication workflow has the same mutable action-reference risk.

In @.github/workflows/fern-docs-preview-comment.yml:
- Around line 88-96: Update the BASE_URL handling in the page-link generation so
it preserves the complete PREVIEW_URL, including any configured instance path
such as /nodewright, before appending each slug. Keep the existing PAGE_LINKS jq
mapping and slug filtering behavior unchanged.
- Around line 37-42: Update the Read PR metadata step and its downstream
workflow logic to resolve the pull request number and head ref from trusted
workflow-run data or the GitHub API rather than uploaded pr_number and head_ref
files; support fork runs where workflow_run.pull_requests may be empty, fail
closed when no PR is resolved, and use the resolved identity for comment
operations.
- Around line 124-133: Add workflow-level concurrency to serialize
preview-comment runs per pull request, using
github.event.workflow_run.pull_requests[0].number as the concurrency key and
setting cancel-in-progress to true. Keep the existing COMMENT_ID lookup and
create-or-update behavior unchanged.

In @.github/workflows/publish-fern-docs.yml:
- Around line 64-67: Update the version-stamping logic in the publish workflow
to use GITHUB_REF_NAME for tag-triggered docs/v* pushes instead of querying the
latest GitHub release. For manual dispatches, require and validate an explicit
version input, then use that value in the display-name replacement; preserve the
existing behavior when no valid version is available.
- Around line 76-78: Update the shell options before the fern generate pipeline
to enable errexit alongside pipefail and nounset, using set -euo pipefail, so
failures from fern generate --docs cause the workflow step to fail immediately.
- Around line 59-60: Update the version configured in fern/fern.config.json from
the mutable latest tag to the exact validated x.y.z Fern CLI release, so the
existing npm install command pins that version in CI.

In `@docs/getting-started/installation.md`:
- Around line 22-24: Remove the blank line between the two adjacent blockquote
paragraphs in the installation documentation so the “Where things live” and
“Migrating from” lines remain contiguous within one blockquote.

In `@fern/docs.yml`:
- Around line 25-27: Resolve the invalid experimental.mdx-components
configuration by either removing the ./components entry or creating the
referenced fern/components directory; ensure fern check no longer encounters a
missing path.

🚀 Performance & Scalability | 🔵 Trivial

Add concurrency cancellation for pull-request checks.

The workflow has no concurrency group. Rapid updates to one pull request can run overlapping ten-minute checks and consume runner capacity. Add a workflow-level group keyed by pull request number or ref with cancel-in-progress: true.

Pin the Fern CLI to an exact reviewed version.

fern/fern.config.json sets "version": "latest", so the workflow installs a moving npm release. The repository has no npm lockfile or integrity pin for this global installation. Use an exact reviewed fern-api version and a reproducible installation method.

Pin all external GitHub Actions to immutable commit SHAs.

The preview-build and publication workflows use mutable action tags. Replace every external action reference in these workflows with reviewed full commit SHAs, retaining the release versions in comments, so later tag changes cannot alter documentation build or publication behavior.

Stamp the version from the publication target.

For a docs/v* push, this fetches GitHub’s current latest release instead of the triggering documentation tag. If the latest release differs or does not exist, the published site gets an incorrect or missing version label. Derive the version from GITHUB_REF_NAME for tag events, and require an explicit version input for manual dispatch.

fern/versions/*.yml basenames won't resolve against the docs/v* tag convention

In .github/workflows/publish-fern-docs.yml, the "Checkout frozen version content" step derives a git ref directly from the version file's basename:

version=$(basename "$version_file" .yml)
if git rev-parse "$version" >/dev/null 2>&1; then
  ...
  git archive "$version" -- docs/ | tar -x --strip-components=1 -C "fern/versions/${version}-content"
else
  echo "::warning::Tag $version not found — skipping content checkout"
fi

So fern/versions/v1.0.0.yml resolves to the ref v1.0.0, while the publish trigger convention established by this same workflow is docs/v1.0.0:

on:
  push:
    tags:
      - 'docs/v*'

Those two naming schemes don't meet. If someone later adds version files named after the docs tags they cut (the natural assumption), git rev-parse misses and the step emits a ::warning:: and skips — the publish still succeeds, just silently missing that version's frozen content. A warning in a green run is easy to miss on a job whose whole purpose is publishing.

Worth noting the repo's tag inventory today: 56 tags, all component-prefixed (operator/*, chart/*, agent/*, cli/*) except a single bare v0.0.0. There's no existing bare-vX.Y.Z series for these basenames to match against, so whatever convention lands here is being established fresh rather than inherited.

This is inert at the moment — the PR ships no fern/versions/ directory and no versions: key in fern/docs.yml, so the loop's [ -e "$version_file" ] || continue guard skips it entirely. Flagging it now while the scaffold is being set rather than after the first frozen version is added.

A couple of options:

  1. Strip the prefix at resolution time, so the file basename and the tag stay legible as the same version: git rev-parse "docs/${version}", or try docs/$version then fall back to $version.
  2. Keep the current behavior and document in fern/versions/ (a README or a comment in the workflow step) that the basename is a literal git ref, not a docs tag.

Either way, promoting the else branch from ::warning:: to a hard failure would be worth considering — if a version file exists, its content going missing from the published site is a defect, not a soft skip.

Replace hand-written workflows with the github-markdown-to-fern skill
templates, adapted for NodeWright's action-ref convention (@v7/@v4).
Adds full version registration/pruning/auto-PR on release, MDX
sanitization of frozen content, stricter validation, and concurrency
groups. Fixes BASE_URL stripping instance path in preview links,
removes nonexistent mdx-components config, and fixes MD028 lint.

Fail when frozen version content is unavailable.

A registered version requires its matching tag content. This warning uploads an incomplete artifact and moves the failure to the preview workflow. Emit an error and exit nonzero.

Do not interpolate release fields into shell source.

Line 107 renders github.event.release.tag_name inside a shell assignment. Shell expansion occurs before the semver check. A release tag containing shell syntax can execute commands with the workflow token.

Pass release fields through env, then assign TAG="$RELEASE_TAG" and IS_PRERELEASE="$RELEASE_PRERELEASE".

Use the docs/v* source-tag convention consistently.

The PR objective specifies docs/v* tags. The resolver rejects docs/v1.2.3, and both frozen-content loops look for refs/tags/v1.2.3 from the version filename. Normalize source tags and display versions separately. Use docs/vX.Y.Z for Git operations and vX.Y.Z for Fern filenames, slugs, and display names.

Configure the pull secret before installing the release.

When private registries are used, this flow creates node-init-secret after helm install and never sets imagePullSecret. The chart default is empty, so workloads will not reference this secret and can enter ImagePullBackOff. Create the secret first and pass --set imagePullSecret=node-init-secret, or provide the equivalent values file.
