Reminders

  • See the README for more details on how to work with the Rancher docs.

  • Verify if changes pertain to other versions of Rancher. If they do, finalize the edits on one version of the page, then apply the edits to the other versions.

  • If the pull request is dependent on an upcoming release, remember to add a "MERGE ON RELEASE" label and set the proper milestone.

Description

RKE1 reached EOL and is no longer default in Rancher 2.12. The "Node-agent" (cattle-node-agent) documentation should be replaced with "rancher-system-agent" which is used in RKE2/K3s clusters.

Changes:

  • Renamed section "Node Agents" → "Rancher System Agent"
  • Replaced cattle-node-agentrancher-system-agent references
  • Updated description to specify RKE2 and K3s clusters
  • Updated architecture diagram SVG label from "Node Agent" to "Rancher System Agent"
  • Fixed anchor links to match new section name

Files updated:

  • docs/reference-guides/rancher-manager-architecture/communicating-with-downstream-user-clusters.md
  • versioned_docs/version-2.12/.../communicating-with-downstream-user-clusters.md
  • versioned_docs/version-2.13/.../communicating-with-downstream-user-clusters.md
  • static/img/rancher-architecture-cluster-controller.svg

Comments

Older versioned docs (v2.11 and earlier) intentionally left unchanged as they still document RKE1 clusters.
