What is a group of one or more containers in a Kubernetes cluster called?

A group of one or more containers in a Kubernetes cluster is referred to as a Pod. In Kubernetes, a Pod serves as the basic deployment unit that encapsulates one or more containers, storage resources, a unique network IP, and options for how to run the containers. The intention behind Pods is to allow containers that need to work closely together to share the same resources and network space, facilitating communication and coordination.

Pods can contain multiple containers that are tightly coupled and typically share the same lifecycle, meaning they can be managed together as a single entity. This is particularly useful for applications that require multiple containers to function as a cohesive unit, such as a web server combined with a logging or monitoring agent.

In this context:

• Helm does not represent a group of containers; it is a package manager for Kubernetes that helps deploy applications easily.

• A Pilot is not a recognized term in Kubernetes terminology—it may refer to Google Cloud's Istio Pilot but is not related to Pods.

• A Node refers to a physical or virtual machine in a Kubernetes cluster where Pods are scheduled to run. Nodes manage the networking and storage resources but are not a container grouping themselves.

Therefore, the terminology in Kubernetes aligns with defining a Pod as the group of one or more containers,
