Wrapper around a single container Kubernetes manages Pods rather than managing Most common Kubernetes use case in this case, you can think of a Pod as a

Pods in a Kubernetes cluster are used in two main ways: If your Pods need to track state, consider the Instead, create them using workload resources such as Deployment or Job. Usually you don't need to create Pods directly, even singleton Pods. See Working with Pods for more information on how Pods are used Pods are generally not created directly and are created using workload resources. Once your application is running, you might want to make it available on the internet as Removes Jobs once a defined time has passed since they completed. The time-to-live after finished controller.There are two supporting concepts that provide backgrounds about how Kubernetes manages podsįrom your cluster after their owning resource has been removed.

To learn about Kubernetes' mechanisms for separating code from configuration,

Run a stateful application either as a single instance.

Run a stateless application using a Deployment.

Then you can implement or install an extension that does provide that feature. Stop work unless all the Pods are available (perhaps for some high-throughput distributed task), For example, if you wanted to run a group of Pods for your application but You can add in a third-party workload resource if you want a specific behavior that's not part In the wider Kubernetes ecosystem, you can find third-party workload resources that provide The control plane schedules a Pod for that DaemonSet onto the new node.ĭefine tasks that run to completion and then stop.

However, to make life considerably easier, you don't need to manage each Pod directly. Would need to create a new Pod to recover, even if the node later becomes healthy. Kubernetes treats that level of failure as final: you Node where that pod is running means thatĪll the pods on that node fail.
