如果你有**多个容器**，可能每个容器运行一个**单独进程**（例如在 **Kubernetes** 集群中），那么你可能希望使用一个**单独的容器**来执行**前置步骤**，在一个容器中运行一个进程，**在**启动那些复制的 worker 容器**之前**完成。

/// info | 信息

如果你使用 Kubernetes，这通常会是一个 [Init Container](https://kubernetes.io/docs/concepts/workloads/pods/init-containers/)。

///

如果在你的用例中，**并行多次**运行这些前置步骤没有问题（例如你不是在跑数据库迁移，而只是检查数据库是否就绪），那么你也可以把这些步骤放在每个容器中，在启动主进程之前执行。

statically to `IfNotPresent` for all required images. If you want to always pull the latest images before cluster init (as `Always` would do), run `kubeadm config images pull` before each `kubeadm init`. If you don't want the kubelet to pull any images at `kubeadm init` time, for example if you don't have an internet connection, you can also run `kubeadm config images pull` before `kubeadm init` or side-load the images some other way (such as `docker load -i image.tar`). Having the images locally cached...

- Joining control plane nodes to a HA cluster can now be simplified by enabling the optional automatic copy of certificates from an existing control plane node.
- You can now use `kubeadm init --experimental-upload-certs` and `kubeadm join --experimental-control-plane --certificate-key`.
