PostgreSQL in Kubernetes
This course provides an introduction to Kubernetes itself and to Kubernetes resources, which are needed in order to manage PostgreSQL. The aim is to gain insights on how PostgreSQL works best within the Kubernetes ecosystem and to overcome challenges of managing multiple PostgreSQL clusters. We will discuss the high availability of PostgreSQL running in Kubernetes, learn how automatic failovers are triggered and cover the options of managing backups and everything else to satisfy all production needs.
