+title: "Kubernetes 1.29: PodReadyToStartContainersCondition Moves to Beta"
+date: 2023-12-19
+slug: pod-ready-to-start-containers-condition-now-in-beta
+---
+
+**Author**: zefeng chen, Kevin Hannon(Red Hat)
+
+
+With the recent release of Kubernetes 1.29, the `PodReadyToStartContainers`[condition](/docs/concepts/workloads/pods/pod-lifecycle/#pod-conditions) is available by default.
+The kubelet manages the value for that condition throughout a Pod's lifecycle, 
+in the status field of a Pod. The kubelet will use the `PodReadyToStartContainers`
+condition to accurately surface the initialization state of a Pod,
+from the perspective of Pod sandbox creation and network configuration by a container runtime.
+
+## What's the motivation for this feature?
+
+Cluster administrators do not have a clear and easily accessible way to view the completion of Pod's sandbox creation
+and initialization. As of 1.28, the Initialized condition in Pods tracks the execution of init containers. 
+However, it has limitations in accurately reflecting the completion of sandbox creation and readiness to start containers for all Pods in a cluster. 
+This distinction is particularly important in multi-tenant clusters where tenants own the Pod specifications, including the set of init containers, 
+while cluster administrators manage storage plugins, networking plugins, and container runtime handlers. 
+Therefore, there is a need for an improved mechanism to provide cluster administrators with a clear and 
+comprehensive view of Pod sandbox creation completion and container readiness.
+
+## What's the benefit?
+
+1.Improved Visibility: Cluster administrators gain a clearer and more comprehensive view of Pod sandbox creation completion and container readiness. 
+This enhanced visibility allows them to make better-informed decisions and troubleshoot issues more effectively.
+
+2.Metric Collection and Monitoring: Monitoring services can leverage the fields associated with the PodReadyToStartContainers condition to 
+report sandbox creation state and latency. 
+Metrics can be collected at per-Pod cardinality or aggregated based on various
+properties of the Pod, such as `volumes`, `runtimeClassName`, custom annotations for CNI 
+and IPAM plugins or arbitrary labels and annotations, and `storageClassName` of 
+PersistentVolumeClaims.
+This enables comprehensive monitoring and analysis of Pod readiness across the cluster.
+
+3.Enhanced Troubleshooting: With a more accurate representation of Pod sandbox creation and container readiness, 
+cluster administrators can quickly identify and address any issues that may arise during the initialization process. 
+This leads to improved troubleshooting capabilities and reduced downtime.
+
+### What’s next?
+
+Due to feedback and adoption, the Kubernetes team promoted `PodReadyToStartContainersCondition` to Beta in 1.29. 
+Your comments will help determine if this condition continues forward to get promoted to GA, 
+so please submit additional feedback on this feature!
+
+### How can I learn more?
+
+Please check out the
+[documentation](/docs/concepts/workloads/pods/pod-lifecycle/) for the
+`PodReadyToStartContainersCondition` to learn more about it and how it fits in relation to
+other Pod conditions.
+
+### How to get involved?
+
+This feature is driven by the SIG Node community. Please join us to connect with
+the community and share your ideas and feedback around the above feature and
+beyond. We look forward to hearing from you!
