Post-Swarm: node-exporter must run standalone with pid:host, since Swarm mode blocked it and cross-node /proc namespaces contaminated swap metrics. Marks the stacks/ definition superseded. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

# SUPERSEDED 2026-03-21: Do NOT deploy this as a Swarm stack.
|
|
# Swarm mode blocks pid: host, causing cross-node /proc namespace contamination
|
|
# where node-exporter reads wrong host's memory metrics.
|
|
# Use standalone Compose on each node instead:
|
|
# compose/hf-pdocker-01/node-exporter/docker-compose.yml
|
|
# compose/hf-pdocker-02/node-exporter/docker-compose.yml
|
|
# compose/bart/node-exporter/docker-compose.yml
