A Kubernetes pod is the smallest and simplest unit in the Kubernetes object model. It represents a single instance of a running process in a cluster, which can be a container or a group of tightly coupled containers sharing the same network namespace and storage volumes.
Pods are used to deploy and manage applications on Kubernetes clusters. They provide a way to encapsulate application logic and dependencies, as well as offer isolation and resource management features such as CPU and memory limits.
Each pod has its own IP address, but it’s not stable since pods may be rescheduled or replaced by new ones. Therefore, pods are usually accessed through services, which provide a stable IP address or DNS name that forwards traffic to one or more pods based on labels.
Kubernetes also provides several mechanisms for managing pods, such as deployments, replicasets, and statefulsets, which help to automate scaling, rolling updates, and recovery from failures.
