Community blueprints for real infrastructure
Reusable, reviewed stacks you can run from the OpenSible console in one click — Kubernetes, service meshes, databases, observability and more.
PostgreSQL HA (Patroni + etcd)
3-node PostgreSQL HA cluster managed by Patroni with an embedded etcd v3 DCS. Installs PostgreSQL from PGDG, runs Patroni from a pinned Python venv, and manages everything via systemd. First node is the initial leader; use 3+ nodes for real HA.
k3s HA (embedded etcd)
Lightweight k3s cluster with embedded etcd and Longhorn storage.
Uninstall — PostgreSQL HA (Patroni + etcd)
Stop patroni + etcd, kill leftover postgres processes, purge PGDG packages, remove /opt/patroni venv, /etc/patroni, /var/lib/patroni, /var/lib/etcd and /var/lib/postgresql.
Uninstall — Kubernetes (kubeadm / k3s)
Completely remove a kubeadm or k3s cluster from selected nodes. Auto-detects the cluster type, drains, resets, removes packages, deletes etcd/CNI data, flushes iptables and cleans images.
