What is Kubernetes?

Kubernetes (K8S) is an open-source system for managing containerized applications, including:

Scheduling

Deploy containers across a cluster of servers, using the available resources (data centers, servers, CPU, memory, ports, etc.) as efficiently as possible.

Deployments

Roll out updates to containers using a variety of deployment strategies, such as rolling deployment, blue-green deployment, and canary deployment, and automatically roll back if there’s an error.

Auto healing

Monitor the health of your containers and servers and automatically replace unhealthy ones.

Auto scaling

Scale the number of containers and servers up or down in response to load.

Load balancing

Make your containers accessible to the outside world and distribute traffic across your containers.

Service discovery

Allow containers to find and communicate with each other over the network, automatically routing requests to the proper destination.

Configuration and secrets

Provide containers with environment-specific configuration data and secrets.
