Learn how to deploy stateful databases such as MySQL, PostgreSQL, and MongoDB on Kubernetes by mastering StatefulSets, PersistentVolumes, PVCs, StorageClasses, and related best practices for storage, scaling, backup, monitoring, and disaster recovery.
This article introduces ten essential Kubernetes technologies—including Helm Charts, Operators, Service Mesh, StatefulSets, CRDs, Network Policies, Pod Disruption Budgets, HPA, Persistent Volumes, and Ingress Controllers—explaining their core concepts, key capabilities, and how they improve application reliability, scalability, and security.
Facing the complexities of running stateful services like Elasticsearch and ClickHouse in production, Bilibili’s infrastructure team detailed their migration to Kubernetes, describing the architectural design, custom operators, storage provisioning with LVM, network configuration, high‑availability strategies, observability, and the resulting cost, quality, and efficiency gains.
