PostgreSQL on Docker

Containers in Docker, combined with the Kubernetes framework, provide capabilities for high availability (HA) and disaster recovery (DR) in containerized environments. Kubernetes, as a container orchestration platform, offers features such as automatic scaling, load balancing, and self-healing, which contribute to the high availability of applications running in containers. Through Kubernetes, containers can be deployed across multiple nodes or hosts, distributing the workload and ensuring redundancy. If a container or node fails, Kubernetes can automatically reschedule and restart the affected containers on healthy nodes, minimizing downtime and maintaining service availability.
