Welcome to UPMIO, a comprehensive open source platform designed to seamlessly manage databases and middleware within Kubernetes environments, covering the entire operational lifecycle from initial deployment to ongoing maintenance.

UPM (Unified Platform Management) provides cloud-native automated operations and management capabilities for MySQL, Redis, Kafka, Zookeeper, Elasticsearch, and other data services.

Universal workload Operator that provides Unit and UnitSet custom resources, supporting unified orchestration and management of various databases and middleware.

Advanced operations Operator that provides automated management for complex operational scenarios such as MySQL master-slave replication, Redis clusters, and ProxySQL synchronization.

Containerization and Kubernetes deployment system for database and middleware components. Provides production-ready Helm charts with unified package management, security-hardened containers, and comprehensive monitoring for MySQL, PostgreSQL, Redis, Kafka, Elasticsearch, and other data services.

The main task of the operator is to bring the state of the cluster in line with what is declared by the user in the custom resources. This process of constant watching and adjustment is called the “Reconciliation cycle” - it is the operator’s workflow.

The basic workflow of working with the operator can be simplified as the following diagram:

• Operator declares and owns resources of unit-operator & compose-operator.
• Kubernetes validates of the resource according to the specification from CRD (see more in custom resources ).
• Operator subscribed to change events (create, update, delete) for related resources.
• When an event occurs, the operator reacts and updates the state of the objects in the cluster.
• For some objects in the cluster the reconciliation cycle is performed at a given interval, even without the occurrence of change events.
