Details

There are two primary approaches to managing applications on Kubernetes - StatefulSets and Deployments. StatefulSets, which require persistent storage, manage stateful workloads such as a MySQL deployment on Kubernetes. Deployments provide a way to manage stateless applications such as websites, which often do not need to maintain their internal state.

A DaemonSets is another workload management type available to a Kubernetes controller. Daemonsets ensure a replica of a Pod will always run on all or some of the cluster’s Nodes, and you’ll typically use it for cluster storage daemons, logging agents, or monitoring systems.

• How to deploy and manage stateless applications
• How to perform a rolling update and rollback
