learn-site-structure

This skill is the single place to learn how content in this repo (and adjacent Netdata-org repos) becomes published pages on the Netdata learn site (learn.netdata.cloud). It documents:

• the <repo>/docs/.map/map.yaml source-of-truth that every

published page must appear in;

• the source-path-to-Learn-URL computation (frontmatter is

injected from map.yaml; the source filesystem path is irrelevant for routing);

• the 16-step ingest/ingest.py orchestrator in the learn repo

(the live one -- NOT the legacy ingest.js);

• the 6 source repositories the pipeline pulls from;
• sidebar autogeneration via Docusaurus autogenerated mode;
• the MDX escape rules every transformation enforces;
• the 4-mechanism redirect stack and how moves auto-redirect;
• the every-3-hours CI ingest cadence and Netlify deploy

contract;

• the part_of_learn: True opt-in for files hand-authored in

the learn repo;

• every surprise, dead artifact, and gotcha worth knowing.

After reading SKILL.md plus the per-domain guides linked below, an assistant should never need to ask "how does a page get added to learn?", "how is the URL computed?", "should I edit this here or in the learn repo?", or "what runs in CI?".

Key concepts (read first)

1. `<repo>/docs/.map/map.yaml` is the lever. Every page

published on Learn appears in this file. To add a page, add a node. To move a page, move its node. To unpublish a page, remove its node and (manually) update the redirect catalog. The schema lives at <repo>/docs/.map/map.schema.json; the authoring guide lives at <repo>/docs/.map/README.md.

1. Source filesystem path is IRRELEVANT for routing. A

doc's destination URL on Learn is computed from sidebar_label + learn_rel_path injected from map.yaml, NOT from where the file lives in this repo. Renaming a source file does not break the URL; renaming the meta.label in map.yaml DOES (and triggers an auto-redirect).

1. **The live orchestrator is ingest/ingest.py. Ignore

ingest.js and ingest.md.** Both are legacy. The README at the learn repo root and docs/.map/README.md document the live Python flow. Don't edit ingest.js; don't trust ingest.md.

1. Sidebar is autogenerated. ${NETDATA_REPOS_DIR}/learn/sidebars.js

is one line: {type: "autogenerated", dirName: "."}. Order is driven by sidebar_position frontmatter that ingest assigns from map.yaml traversal order. To reorder the sidebar, reorder rows in map.yaml.

1. `docs/` (in the learn repo) is OWNED by ingest. Anything

under ${NETDATA_REPOS_DIR}/learn/docs/ is cleaned and regenerated each ingest run, EXCEPT files marked part_of_learn: True (currently only docs/ask-nedi.mdx). Do NOT hand-edit docs/ in the learn repo unless you set that flag and accept that this is a hand-authored exception.

1. 6 source repositories feed Learn. This repo

(netdata/netdata) is the bulk; also pulled: netdata-cloud-onprem, .github, agent-service-discovery, netdata-grafana-datasource-plugin, helmchart. Each can be overridden locally with --repos for testing.

1. Auto-redirects on move/rename, manual on delete.

Moving or renaming a page in map.yaml produces an automatic Netlify redirect from the old URL to the new target. Deleting a page requires manual surgery on ${NETDATA_REPOS_DIR}/learn/LegacyLearnCorrelateLinksWithGHURLs.json (documented in <repo>/docs/.map/README.md).

Table of contents

Live how-to rule (mandatory)

If an assistant is asked a concrete question about how a Learn page is produced that is NOT already documented under how-tos/ or one of the per-domain guides above, AND answering it requires non-trivial analysis (reading ingest.py or related scripts, running ingest locally, checking cross-references between this repo's map.yaml and the learn-repo output), the assistant MUST author a new how-to under how-tos/<slug>.md and add a one-line entry to how-tos/INDEX.md BEFORE completing the task. This rule is durable.

Path discipline

This skill follows <repo>/.agents/sow/specs/sensitive-data-discipline.md:

• This repo's files: repo-relative

(<repo>/docs/.map/map.yaml, <repo>/docs/...).

• Learn repo files: ${NETDATA_REPOS_DIR}/learn/... (env-key

from .env).

• Other Netdata-org sibling repos: ${NETDATA_REPOS_DIR}/<repo>/....
• No literal home-directory or workstation-root paths anywhere.
