用於測試較新的 Kubernetes 版本、Cloud Service Mesh 功能和 API,以便在這些版本升級至正式版可用狀態後,加快產品上市時間。
在發布版本中註冊叢集
Cloud Service Mesh 經常發布更新,提供安全性更新、修正已知問題及推出新功能。有了 Managed Cloud Service Mesh 發布版本,您就能在穩定性與功能組合之間取得平衡。在發布版本中註冊新叢集之後,Google 會自動管理該叢集的版本和升級頻率。控制層和資料層會定期升級。

You can use this information to keep your clusters updated for\nstability and security with minimal disruptions to your workloads.\n\nSet up multiple environments\n----------------------------\n\nAs part of your workflow for delivering software updates, we recommend that you\nuse multiple environments. Multiple environments help you minimize risk and\nunwanted downtime by testing software and infrastructure updates separately from\nyour production environment. At minimum, you should have a production\nenvironment and a pre-production or test environment.\n\nConsider the following recommended environments:\n\nEnroll in release channels\n--------------------------\n\nCloud Service Mesh often releases updates, to deliver security updates, fix\nknown issues, and introduce new features. Managed Cloud Service Mesh\n[release channels](/service-mesh/v1.24/docs/managed/select-a-release-channel) offer you the\nability to balance between stability and feature set. When you enroll a new\ncluster in a release channel, Google automatically manages the version and\nupgrade cadence for the cluster. Control planes and data planes are upgraded on\na regular basis.\n\nSimilarly for GKE clusters on Google Cloud, we recommend\nenrolling the\n[GKE clusters in a release channel](https://cloud.google.com/kubernetes-engine/docs/concepts/release-channels). For more information, see\n[GKE release channels](/kubernetes-engine/docs/concepts/release-channels).\nAdditionally, if you have clusters enrolled in the static channel, ensure you\ncheck the [supported platforms](/service-mesh/v1.24/docs/supported-platforms)\nto confirm compatibility.\n\nTo keep clusters up-to-date with the latest Cloud Service Mesh and\nKubernetes updates, here are some recommended environments and the respective\nrelease channels the clusters should be enrolled in:\n\nCreate a continuous upgrade strategy\n------------------------------------\n\nAfter enrolling your cluster in a release channel, that cluster is regularly\nupgraded to the version that meets the quality and stability bar for the\nchannel. These updates include security and bug fixes, applied with increasing\nscrutiny at each channel:\n\n- Patches are pushed out to control plane and data plane in all channels gradually, accumulating soak time in rapid and regular channels before landing in the stable channel.\n- The control plane is upgraded first, followed by data plane.\n- Cloud Service Mesh will automatically roll out patches to channels based on their criticality and importance.\n\n### Receive updates about new Cloud Service Mesh versions\n\nInformation about new versions is published to the main\n[Cloud Service Mesh release notes](/service-mesh/v1.24/docs/release-notes)\npage, as well as to an RSS feed.\n\nWhat's next\n-----------\n\n- Learn more about [Cloud Service Mesh release channels](/service-mesh/v1.24/docs/managed/select-a-release-channel).\n- Learn about [Cloud Service Mesh versioning](/service-mesh/versions)"]]
