- More information
Kubernetes is an open-source platform for automating deployment, scaling, and operations of application containers across clusters of hosts, providing container-centric infrastructure. Kubernetes can schedule and run application containers on clusters of physical or virtual machines. However, Kubernetes also allows developers to ‘cut the cord’ to physical and virtual machines, moving from a host-centric infrastructure to a container-centric one, providing the full advantages and benefits inherent to containers. Kubernetes provides the infrastructure to build a container-centric development environment.
Kubernetes cluster is a set of nodes: master node and worker node. Multi-master mode is needed for deploying the HA cluster.
