# ============================================
# Renovate Bot - Self-hosted dependency updater
# ============================================
# https://docs.renovatebot.com
# Image: renovate/renovate (plain tag = minimal image, "formerly slim";
# -slim suffix was retired after v37.440.x, so we pin the plain tag)
#
# PILOT SCOPE (intentionally narrow):
# Runs weekly (Sun 04:00 Europe/Budapest) as a CronJob and opens
# dependency-update PRs against admin/homelab-manifests on Gitea.
# Only the `kubernetes` and `helm-values` managers are enabled, and a
# default-deny packageRule limits updates to exactly four pilot images:
# - ghcr.io/thomiceli/opengist
# - louislam/uptime-kuma
# - f0rc3/gokapi
# - docker.io/calcom/cal.com
# minor/patch -> PR with Gitea native auto-merge; major -> waits for
# manual approval via a checkbox on the Dependency Dashboard issue.
#
# Stateless & ephemeral: no Service, Ingress, or PVC. Writable /tmp is an
# emptyDir (root FS is read-only); Renovate uses it for git clones + cache.
#
# Secrets (created manually, NOT in git) come from Secret `renovate-secrets`:
# - RENOVATE_TOKEN (Gitea PAT)
# - RENOVATE_GITHUB_COM_TOKEN (GitHub PAT, for release notes)
# ============================================
