"PostgreSQL In Great STYle": Postgres, Infras, Graphics, Service, Toolbox, it's all Yours.
—— Battery-Included, Local-First PostgreSQL Distribution as an Open-Source RDS Alternative
Website | Demo | Blog | Discuss | Discord | Roadmap | 站点 | 博客
Get Started with the latest v2.6.0 release:
curl -fsSL https://get.pigsty.cc/latest
Pigsty is your postgres, infra, grafana service toolbox, check Feature | 特性 and Demo for details.
Setup everything with one command! Check Get Started | 快速上手 for details.
Prepare a fresh Linux x86_64 node that runs compatible OS distros:
# run as the admin user with no password ssh & sudo capability
curl -fsSL https://get.pigsty.cc/latest | bash
cd ~/pigsty; ./bootstrap; ./configure; ./install.yml;Then you will have a pigsty singleton node ready, with Web Services on port 80/443 and Postgres on port 5432.

Pigsty uses a modular design. There are six default modules available:
INFRA: Local yum repo, Nginx, DNS, and entire Prometheus & Grafana observability stack.NODE: Init node name, repo, pkg, NTP, ssh, admin, tune, expose services, collect logs & metrics.ETCD: Init etcd cluster for HA Postgres DCS or Kubernetes, used as distributed config store.PGSQL: Autonomous self-healing PostgreSQL cluster powered by Patroni, Pgbouncer, PgBackrest & HAProxyREDIS: Deploy Redis servers in standalone master-replica, sentinel, and native cluster mode, optional.MINIO: S3-compatible object storage service used as an optional central backup server forPGSQL, optional.
You can compose them freely in a declarative manner. If you want host monitoring, INFRA & NODE will suffice.
ETCD and PGSQL are used for HA PG clusters, install them on multiple nodes will automatically form a HA cluster.
You can also reuse pigsty infra and develop your own modules, KAFKA, MYSQL, GPSQL, and more will come.
The default install.yml playbook in Get Started will install INFRA, NODE, ETCD & PGSQL on the current node.
which gives you a battery-included PostgreSQL singleton instance (admin_ip:5432) with everything ready.
This node can be used as an admin center & infra provider to manage, deploy & monitor more nodes & clusters.
To deploy a 3-node HA Postgres Cluster with streaming replication, define a new cluster on all.children.pg-test of pigsty.yml:
pg-test:
hosts:
10.10.10.11: { pg_seq: 1, pg_role: primary }
10.10.10.12: { pg_seq: 2, pg_role: replica }
10.10.10.13: { pg_seq: 3, pg_role: offline }
vars: { pg_cluster: pg-test }Then create it with built-in playbooks:
bin/pgsql-add pg-test # init pg-test cluster 
You can deploy different kinds of instance roles such as primary, replica, offline, delayed, sync standby, and different kinds of clusters, such as standby clusters, Citus clusters, and even Redis / MinIO / Etcd clusters.
