Автоматизация управления ClickHouse-кластерами в Kubernetes Владислав Клименко и Валерий Панов K8s? Что это? K8s is the new Linux Это платформа с открытым кодом. позволяющая: • строить системы на основе запросов (OLAP), с открытым кодом. Зачем ClickHouse в Kubernetes? • Все компоненты системы уже в k8s. • Максимальная унификация управления. • Нужно быстро строить хранилища данных. • Нужна максимальная Лицензия: Apache 2.0, Распространяется как Docker image ClickHouse cluster resources kubectl apply K8S API Спецификация ClickHouse on Kubernetes – components Shard 1 Replica 1 Zookeeper Services
