AGENTS.md

Pomerium documentation site built with Docusaurus 3.8 (React + MDX). Published at https://pomerium.com/docs. Pomerium is an identity-aware proxy for zero-trust access.

Commands

npm start                # Dev server on localhost:3001 (hot-reload)
npm run build            # Production build to /build/
npm run format           # Auto-fix formatting with oxfmt
npm run format:check     # Check formatting (no changes)
npm run check            # Run formatting and spelling checks
npm run cspell           # Spell-check tracked source files
npm run clear            # Clear Docusaurus cache (useful if build fails)

This repo does not use the Python pre-commit framework. The CI pre-commit check runs the repo scripts directly (npm run format:check, npm run cspell), and the same commands are available locally via npm run check.

Architecture

Content structure

All documentation lives in content/ (not docs/). The Docusaurus routeBasePath is / and the path is content, so files at content/docs/foo.mdx become routes at /docs/foo.

content/
  docs/
    get-started/      # Quickstart and fundamentals
    deploy/           # Deployment guides (cloud, k8s, enterprise, clients)
    capabilities/     # Core features (auth, authz, routing, MCP, SSH, etc.)
    reference/        # Configuration reference (~30 .mdx files)
    guides/           # How-to guides for integrations (~50 files)
    integrations/     # Identity provider setup (OIDC, Okta, Azure AD, etc.)
    internals/        # Architecture documentation
    admonitions/      # Reusable MDX snippet files (prefixed with _)
  examples/           # Code examples (Docker, K8s, Terraform, etc.)

Three sidebars (sidebars.js)

• documentation: Main docs (Get Started, Deploy, Capabilities, Internals, Integrations)
• reference: Configuration reference (auto-generated from docs/reference/)
• guides: How-to guides (auto-generated from docs/guides/)

Enterprise-only sidebar items use className: 'enterprise'.

Custom components

• src/components/ReferenceTable.js — MUI DataGridPro for config reference, reads from content/docs/reference/reference.json
• src/theme/Admonition/Types.js — Custom :::enterprise admonition type
• plugins/llms-txt-plugin.js — Generates /llms.txt during build for LLM consumption

Key config files

• docusaurus.config.js — Site config. Broken links set to throw (both onBrokenLinks and onBrokenMarkdownLinks)
• .oxfmtrc.json — 80 chars, single quotes, trailing commas, proseWrap: never
• cspell.json — Custom dictionary (~290 words). Add new Pomerium-specific terms here when cspell fails on intentional words

Content Authoring Conventions

Frontmatter

---
title: 'Page Title'
sidebar_label: 'Menu Label'
description: 'SEO description'
keywords: [pomerium, relevant, terms]
lang: en-US
---

Admonitions

Standard types plus a custom :::enterprise for enterprise-only features:

:::note :::tip :::info :::caution :::danger :::enterprise

Tabs (Zero vs Core)

import TabItem from '@theme/TabItem';
import Tabs from '@theme/Tabs';

<Tabs>
  <TabItem value="zero" label="Pomerium Zero">
    ...
  </TabItem>
  <TabItem value="core" label="Pomerium Core">
    ...
  </TabItem>
</Tabs>

Reusable snippets

Stored as content/docs/admonitions/_name.mdx (underscore prefix). Imported as:

import SemanticVersioning from '@site/content/docs/admonitions/_semantic-versioning.mdx';

<SemanticVersioning />

Diagrams

Mermaid is enabled. Use fenced code blocks with mermaid language.

Syntax highlighting

Extra Prism languages available: actionscript, log, ini, nginx, rego, hcl, shell-session, json.

Commit Messages

Follow the pattern: docs: description of change (#PR) or docs(scope): description (#PR).

Important Notes

• Broken links cause build failures (onBrokenLinks: 'throw'). Always verify internal link paths match file structure.
• Images go in content/docs/[section]/img/ directories alongside the content.
• The content/docs/deploy/k8s/reference.md file is excluded from oxfmt formatting (auto-generated).
• Prose wrap is set to never — oxfmt won't reflow markdown text.
• API docs are auto-generated from an OpenAPI spec via redocusaurus at /docs/api/.

Cutting a new docs version

main is the canonical, indexed docs at www.pomerium.com/docs/ (it is the Netlify production branch; only its production build is indexable — see plugins/robots-txt-plugin.js). Numbered release branches are noindex pinned snapshots served at <version>.docs.pomerium.com. Policy: keep the latest stable pin and the one before it live; everything older redirects to canonical docs.

A release cut (e.g. 0-33-0):

1. Cut the branch from main. On the new branch only, override presets[0].docs.versions.current.label in docusaurus.config.ts to that version (e.g. v0.33) so the snapshot doesn't call itself "Latest (main)". The robots plugin needs no per-branch changes — numbered branches build noindex automatically. (Branches cut before this plugin landed carry the old allow-by-regex plugin and need explicit demotion via static/_headers.)
2. Confirm the pin serves — Netlify maps <branch>.docs.pomerium.com to the branch deploy automatically under the docs.pomerium.com custom domain; the GCP docs LB passes unmatched *.docs.pomerium.com hosts through to Netlify with the Host header preserved.
3. src/components/docVersions.json + navbar dropdown in docusaurus.config.ts (themeConfig.navbar.items[*].dropdownItemsAfter), on main: relabel the new pin "Latest stable (vX.Y)", demote the previous one to plain vX.Y, drop the oldest. Keep both files in sync. Backport the same dropdown update to still-live pinned branches. Run npm run format + npm run build + npm run cspell -- "**/*" before committing.
4. Retire the oldest pin — ops appends it to redirect_versions in infrastructure-terraform/terraform/gcp/public-prd/docs.tf (applied via Terraform Cloud), which 301s the hostname to canonical docs.

Verify after deploy: the new pin returns 200 with a valid cert and X-Robots-Tag: noindex; the retired version 301s to canonical docs; www.pomerium.com/docs/ still serves main with X-Robots-Tag: all.

Never merge robots/noindex changes (e.g. static/_headers) to a branch while it is Netlify's production branch — they would apply to the live canonical docs, not just a snapshot.
