Kubernetes

According to the Kubernetes website,

"Kubernetes is an open-source system for automating deployment, scaling, and management of containerized applications."

Kubernetes comes from the Greek word κυβερνήτης, which means helmsman or ship pilot. With this analogy in mind, we can think of Kubernetes as the pilot on a ship of containers. Kubernetes is also referred to as k8s (pronounced Kate's), as there are 8 characters between k and s.

Kubernetes offers a very rich set of features for container orchestration. Some of its fully supported features are:

• Automatic bin packing
• Self-healing
• Horizontal scaling
• Service discovery and Load balancing
• Automated rollouts and rollbacks
• Secret and configuration management
• Storage orchestration
• Batch execution
