# GitLab cross-site replication (see
# /home/scooby/.claude/plans/jiggly-snacking-iverson.md) - the chart has
# no support for registering an externally-hosted Gitaly node into an
# existing Praefect virtual storage (confirmed live: no
# virtualStorages[].nodes/address-override key exists in the template,
# gitalyReplicas just counts StatefulSet ordinals). Overriding Praefect's
# rendered config.toml is the only way to add one.
#
# A values-only CONFIG_TEMPLATE_DIRECTORY redirect (extraEnv +
# extraVolumes/extraVolumeMounts) was tried first and confirmed NOT to
# work: charts/gitlab/charts/praefect/templates/statefulset.yaml's own
# volumes: list never calls the gitlab.extraVolumes helper (only
# volumeMounts does) - a chart limitation specific to this subchart, no
# values-only fix exists.
#
# THIS ConfigMap (praefect-ha-config) is deployed as a harmless,
# otherwise-unused object - it exists purely as a git-tracked reference
# copy of the content that actually matters. The REAL live config lives
# on the chart's own gitlab-praefect ConfigMap, which
# argocd-apps/apps/gitlab.yaml's ignoreDifferences now exempts from
# ArgoCD's normal drift-reconciliation (its `data` field specifically) -
# apply this file's content to it directly:
#   kubectl -n gitlab patch configmap gitlab-praefect --type merge \
#     -p "{\"data\":{\"config.toml.tpl\":\"$(kubectl -n gitlab get cm \
#     praefect-ha-config -o jsonpath='{.data.config\.toml\.tpl}' | \
#     python3 -c 'import sys,json; print(json.dumps(sys.stdin.read())[1:-1])')\"}}"
# (or simpler: kubectl -n gitlab get cm praefect-ha-config -o
# jsonpath='{.data}' | kubectl -n gitlab patch cm gitlab-praefect --type
# merge -p "{\"data\":$(cat -)}")
#
# Content below is intentionally byte-identical to the chart's own
# current rendering for the first pass (confirmed live via `kubectl -n
# gitlab get cm gitlab-praefect -o jsonpath='{.data.config\.toml\.tpl}'`)
# - proves the ignoreDifferences + manual-patch mechanism itself doesn't
# break anything, before a follow-up switches addressing to floating
# hostnames and adds the VPS as a 4th node.
