通过使用预制的容器镜像，可以非常轻松地**组合**并使用不同的工具。 例如，尝试一个新的数据库。 在大多数情况下，你可以使用**官方镜像**，只需为其配置环境变量即可。

这样，在许多情况下，你可以了解容器和 Docker，并通过许多不同的工具和组件重复使用这些知识。

- Kubeadm: do not check if the `/etc/kubernetes/manifests` folder is empty on joining worker nodes during preflight ([#104942](https://github.com/kubernetes/kubernetes/pull/104942), [@SataQiu](https://github.com/SataQiu))

    upgrading OkHttp. With this change it is now a regular Java class with
    enum-like constants. Application code that uses enum methods on cipher
    suites (`ordinal()`, `name()`, etc.) will break with this change.

 *  Fix: `CertificatePinner` now matches canonicalized hostnames. Previously
    this was case sensitive. This change should also make it easier to configure

- Kubeadm: fix panic in the command "kubeadm certs check-expiration" when "/etc/kubernetes/pki" exists but cannot be read. ([#124124](https://github.com/kubernetes/kubernetes/pull/124124), [@carlory](https://github.com/carlory)) [SIG Cluster Lifecycle]

- Images for cloud-controller-manager, kube-apiserver, kube-controller-manager, and kube-scheduler now contain a minimal /etc/nsswitch.conf and should respect /etc/hosts for lookups ([#69238](https://github.com/kubernetes/kubernetes/pull/69238), [@BenTheElder](https://github.com/BenTheElder))
