Pod specification
A Pod specification is a declarative Kubernetes configuration that defines a Pod’s containers and related runtime settings.
Kubernetes for Developers
A PodSpec is the Kubernetes specification that defines the containers and settings of a Pod.
- How it is used
- Defines reusable Pod configuration inside controllers or directly for simple workloads.
- How deep it goes
- Explains composition, lifecycle consequences, container fields, and Job retry settings, but not the complete API field reference.
- Examples
- Uses a timeserver Pod manifest and an addwork Job with commands, environment variables, restartPolicy, and backoffLimit.
- What you can do after
- Apply it via kubectl as a standalone Pod or embedded template, while choosing controller-managed recovery when required.

A Pod specification is the declarative configuration describing a Pod's metadata and the containers it should run.
- How it is used
- Models an application component and the containers Kubernetes should run.
- How deep it goes
- Defines required YAML fields and deployment behavior, but defers most optional Pod configuration.
- Examples
- Uses a pi console Pod and a labeled random-number REST API Pod.
- What you can do after
- Operate Pods via kubectl apply, get, logs, describe, watch, and port-forward.
