Kubegres is a Kubernetes operator written in Go that deploys and manages clusters of PostgreSQL instances with streaming replication, automatic failover, and scheduled backups. It provides a simple custom resource (kind: Kubegres) built on Kubebuilder, keeping a minimal codebase compared to other Postgres operators.

Use cases

• deploy a postgres cluster on kubernetes
• set up postgres streaming replication with primary and replicas
• automatic failover when primary postgres pod crashes
• schedule regular postgres data backups to a volume
• manage many self-contained postgres clusters via simple YAML
• run postgres in production on kubernetes without custom docker images

When to choose

• you want a minimalist, easy-to-understand Postgres operator for Kubernetes
• you need out-of-the-box streaming replication and failover
• you want to use official Postgres Docker images without custom images
• you need to run one or many small-to-medium Postgres clusters in production

When to avoid

• you need advanced features like point-in-time recovery, connection pooling, or horizontal scaling beyond streaming replicas
• you are not running on Kubernetes
• you need a highly feature-rich operator with extensive ecosystem support
• you require managed database services rather than self-managed clusters
