Understanding Kubernetes Pods: The Basic Building Blocks of Container Orchestration
In Kubernetes, a Pod is the smallest and simplest unit of the platform’s object model. A Pod is a logical host for one or more containers, and it is used to deploy and manage containerized applications. In this blog post, we will take a closer look at what a Pod is, how it works, and its importance in Kubernetes.
What is a Pod?
A Pod is a basic building block of a Kubernetes cluster, and it represents a single instance of a running process in the platform. Each Pod contains one or more containers, which share the same network namespace and can communicate with each other via interprocess communication (IPC) mechanisms such as shared memory.
How does a Pod work?
When a Pod is created, it is assigned a unique IP address and a set of ports that can be used for communication with other Pods and services in the cluster. The containers running in the Pod can use the localhost address (127.0.0.1) and the assigned ports to communicate with each other.
The containers in a Pod share the same storage volumes, which can be used to share data between the containers. These volumes can be created as empty directories, host-mounted directories, or network storage volumes, depending on the needs of the application.
