PostgreSQL on Kubernetes
PostgreSQL on Kubernetes
In short: Running PostgreSQL on Kubernetes means using an operator — CloudNativePG, Zalando, Crunchy PGO, or Stackgres — to run a primary plus streaming replicas as pods on PersistentVolumeClaims. The operator manages Patroni-style automatic failover, PgBouncer connection pooling, rolling upgrades, and continuous WAL archiving to object storage via pgBackRest or Barman for point-in-time recovery.
Deploy production-grade PostgreSQL on Kubernetes with best-in-class operators, automated failover, rolling upgrades, and cloud-native backup strategies for mission-critical workloads.

Cloud-Native Operations
Why Run PostgreSQL on Kubernetes?
Kubernetes provides the orchestration layer that makes PostgreSQL truly cloud-native with automated operations, self-healing, and infrastructure portability.
Automated Day-2 Operations
Operators handle failover, backups, scaling, and minor version upgrades automatically. Reduce toil and let Kubernetes manage the operational lifecycle of your PostgreSQL clusters.
Self-Healing Infrastructure
When pods crash or nodes fail, Kubernetes automatically restarts pods and the operator promotes replicas. Pod disruption budgets ensure upgrades and maintenance never take down your cluster.
Rolling Upgrades with Zero Downtime
Operators perform rolling upgrades by updating replicas first, then performing a controlled switchover to minimize downtime. PostgreSQL minor and major version upgrades are orchestrated safely.
Infrastructure Portability
Run the same PostgreSQL configuration on EKS, GKE, AKS, or on-premise Kubernetes. Avoid cloud vendor lock-in while maintaining consistent operations across environments.
PostgreSQL on K8s Key Metrics
Methodology
Our PostgreSQL on Kubernetes Implementation Process
A proven methodology for deploying production-ready PostgreSQL on Kubernetes with comprehensive testing and validation.
Assessment & Planning
Evaluate your Kubernetes environment, storage options, and workload requirements. Select the optimal operator and design cluster topology with HA, backup, and monitoring strategies.
Operator & Cluster Setup
Install and configure the chosen operator, deploy PostgreSQL clusters with streaming replication, configure PVCs, resource limits, and connection pooling via PgBouncer.
Integration & Validation
Migrate data, validate application connectivity, perform failover drills, test backup and restore procedures, and benchmark performance under production-like load.
Production & Observability
Go live with Prometheus monitoring, Grafana dashboards, Alertmanager rules, and automated backup schedules. Provide runbooks, training, and ongoing 24/7 support.
