# the Grav container. This script renders pages as markdown into the
# KNELPerfHub git repo and PUSHES; the Cloudron VPS's ukrrs-hub-pull.timer
# git-pulls that repo into the Grav pages dir every 5 min (Grav
# cache.check=file picks changes up). Scraping/collectors run on the
# tooling hosts, not in the app container.
