A Hands-On Guide to Kubernetes: Deployments, StatefulSets, and DaemonSets

This article provides an overview of three key Kubernetes controller types: Deployments, StatefulSets, and DaemonSets. Kubernetes Deployments are used to manage a set of identical pods, ensuring a specified number of replicas are running at all times, making them well-suited for stateless applications like web servers, APIs, and microservices. Kubernetes StatefulSets are designed for stateful applications that require stable network identities and persistent storage, such as databases, distributed systems, and caching. Kubernetes DaemonSets ensure that a copy of a pod runs on all or selected nodes in the cluster, enabling use cases like log collection, monitoring, and security agents that need to be present on every node. The article includes practical deployment examples for each of these Kubernetes controller types.

Storage classes in Kubernetes

The article explains the concept of Storage Classes in Kubernetes, which provide a way to describe different types of storage available in the cluster and manage the dynamic provisioning of Persistent Volumes (PVs). Storage Classes have key components like the Provisioner (the driver responsible for creating volumes), Parameters (specific settings for the provisioner), Reclaim Policy (what happens when a volume is released), and Binding Mode (when a Persistent Volume Claim is bound to a PV). The article walks through creating a simple AWS EBS Storage Class and using it in a Persistent Volume Claim. It highlights how Storage Classes enable applications to automatically get the right type of storage they need, optimizing performance and cost, which is particularly useful for stateful applications that require dynamic storage provisioning.
