Kubernetes is built around a set of core objects that define how applications run.

The most important ones are:

• Pod
• Deployment
• ReplicaSet
• Service
• Namespace

Each object has a specific role in running and managing applications.

—

• Pod → runs your app
• ReplicaSet → keeps pods alive
• Deployment → manages ReplicaSets
• Service → exposes pods
• Namespace → organizes everything
