Kubernetes has a lot of technical terminology. To understand management kubernetes, we need to understand each words. During learning, I’m confusing what they are, and their relationships, during learning.
Container / Pod / Replicaset / Deployment / Service
| Words | Description |
| Container | A container is a lightweight, isolated and portable environment that packages an application and its dependencies Containers run inside Pods and are managed by Kubernetes |
| Pod | Pod is fundamental(minimum) unit of deployment in Kubernetes Pod represents a single instance can contain one or more containers Containers within pod share resources ex, Network, Storage.. |
| Replicaset | ReplicaSet ensures that a specified number of pod replicas are running at all times |
| Deployment | Deployment is a higher-level controller that manages ReplicaSets and provides a declarative way to manage the rollout and scaling of applications (rolling update, rollback) Use this for release management |
| Service | Service in Kubernetes is an abstraction that enables reliable and consistent communication between different components of an application by providing a stable endpoint and load balancing traffic across a set of Pods. Services facilitate both internal and external communication, Communication from outside Deployment -> ReplicaSet -> Pod Service + Deployment |
To manage application in kubernetes, we recognize deployment and service
