RKE，Dockershim 的上游支持从 Kubernetes 1.21 开始。你需要使用 Rancher 2.6 或更高版本才能获取使用 Kubernetes 1.21 的 RKE 的支持。详情请参阅我们的<a href="https://rancher.com/support-maintenance-terms/all-supported-versions/rancher-v2.6.0/" target="_blank" rel="noopener noreferrer">支持矩阵</a>。</p><br><p>Q. 我目前的 RKE 使用 Kubernetes 1.20。为了避免出现不再支持 Dockershim 的情况，我是否需要尽早将 RKE 升级到 Kubernetes 1.21？</p><p>A. 在使用 Kubernetes 1.20 的 RKE 中，Dockershim 版本依然可用，而且在 Kubernetes 1.24 之前不会在上游弃用。Kubernetes 会发出弃用 Dockershim 的警告，而 Rancher 在使用 Kubernetes 1.21 的 RKE 中已经缓解了这个问题。你可以按照计划正常升级到 Kubernetes 1.21，但也应该考虑在升级到 Kubernetes 1.22 时启用外部 Dockershim。在升级到 Kubernetes 1.24 之前，你需要启用外部 Dockershim，此时现有的实现都会被删除。</p><p>有关此移除的更多信息以及时间线，请参见 <a href="https://kubernetes.io/blog/2020/12/02/dockershim-faq/#when-will-dockershim-be-removed" target="_blank" rel="noopener noreferrer">Kubernetes Dockershim 弃用相关的常见问题</a>。</p><br><p>Q: 如果我不想再依赖 Dockershim，我还有什么选择？</p><p>A: 你可以为 Kubernetes 使用不需要 Dockershim 支持的运行时，如 Containerd。RKE2 和 K3s 就是其中的两个选项。</p><br><p>Q: 如果我目前使用 RKE1，但想切换到 RKE2，我可以怎样进行迁移？</p><p>A: Rancher 也在探索就地升级路径的可能性。此外，你始终可以使用 kubectl 将工作负载迁移到另一个集群。</p><br></div><footer class="theme-doc-footer docusaurus-mt-lg"><div
