What types of containers can be inside a pod?

A pod in Kubernetes can contain multiple types of containers that work together to perform a task:

• Application Containers — containers with the main application that perform business logic.
• Init Containers — run before the main containers, performing preparatory tasks such as initialization or environment checks.
• Sidecar Containers — containers that supplement the main application, for example, for logging, proxying, monitoring.

All containers within a pod share network and storage, allowing them to interact efficiently.

Thus, a pod can contain init containers, main containers, and sidecar containers.
