Room 2 - 6 - Đinh Tuấn Phong - Migrate opensource database to Kubernetes easier with Percona Kubernetes Operators
This document discusses running MySQL on Kubernetes with Percona Kubernetes Operators. It provides an introduction to cloud native applications and Kubernetes. It then discusses the benefits and challenges of running MySQL on Kubernetes compared to database-as-a-service options. It introduces Percona Kubernetes Operators for MySQL, which help manage and configure MySQL deployments on Kubernetes. Finally, it discusses how to deploy MySQL with the Percona Kubernetes Operators, including prerequisites, connectivity, architecture, high availability, and monitoring.

- 7. “ Cloud nativeis an approach to building and running applications that fully exploit the advantages of the cloud computing model. When companies build and operate applications using a cloud native architecture, they bring new ideas to market faster and respond sooner to customer demands” Source: Pivotal (VmWare) Cloud native application
- 8. “ Cloud nativecomputing uses an open source software stack to be: • Containerized: Each part (applications, processes, etc.) is packaged it its own container. This facilitates reproducibility, transparency, and resource isolation. • Dynamically orchestrated: Containers are actively scheduled and managed to optimize resource utilization • Microservices-oriented: Applications are segmented into microservices. This significantly increases the overall agility and maintainability of applications. Source: CNCF Cloud native application

- 13. MySQL database inthe cloud Two options DBaaS K8S with application Cloud-vendor provided • AWS RDS (Aurora) MySQL • Google CloudSQL MySQL • Azure Database for MySQL • Oracle MySQL Database service Need to consider the database pods are transient, so the likelihood of database restarts or failovers is higher, DB tasks like backup, replication are different due to added abstractions from containerization
- 14. MySQL on Kubernetes •One platform for everything • No vendor lock-in, portability • Cost-efficient • Challenges and problems • Complexity of Kubernetes • Stateful set for Primary/Replicas • DB replication • High availabity and failover • Storage (PVC/Hostpath) • Services: Read/write and Read Only • Load balancing and Proxy • Configuration • Monitoring agents • Backups • Updates • DR • SSL • ….
- 15. Operators is thekey • Operator is a pod and customer resource definition • Reconcile loop checks K8S API for Customer Resource (CR) • K8S controller are aware of CR creation or changes • Opreator’s code provisions and manages v K8S privities v DB and componets configurations
