Reduce replicas to 1 for workloads that don't need HA in a homelab: - Prometheus 2→1, Alertmanager 2→1 (~4.4GB RAM saved) - cert-manager 3→1 - GitLab: registry 2→1, kas 2→1, sidekiq 2→1, praefect 2→1, pgbouncer-ro 3→1 - Guacamole + guacd 2→1 - Kiali 2→1, ArgoCD server 2→1 - Kyverno background-controller 2→1 - Scylla operator 2→1 - ext-authz-proxy 2→1, netbird-cluster-router 2→1 Kept multi-replica: coredns, envoy-gateway, kyverno admission, vault, argocd-repo-server, gitlab-webservice, istiod, rook-ceph CSI.
