响Node上的现有的Pod。这对于做Node重启之 前的准备⼯作很有⽤。例如，要将node标记为不可调度，可使⽤如下命令： kubectl cordon $NODENAME 请注意，由DaemonSet Controller创建的Pod会绕过Kubernetes调度程序，并且不遵循节点上的unschedulable属性。 因为，我们假设daemon进程属于机器，即使在准备重启时正被耗尽。 ReplicaSet 以及 Deployment ，Pod预期不会终⽌，例如Web服务器。 ReplicationController仅适⽤于 restartPolicy 为Always的Pod。 DaemonSet ，每台机器都需要运⾏⼀个Pod，因为它们提供特定于机器的系统服务。 以上三种类型的Controller都包含⼀个PodTemplate。建议创建适当的Controller，让Controller创建Pod，⽽⾮直接创建 ，Kubelet或Docker）。 Job（作业） 对于可预期会终⽌的Pod（即批处理作业），可以使⽤ Job ⽽⾮ReplicaSet。 DaemonSet 对于提供机器级功能（例如机器监控或⽇志）的Pod，请使⽤ DaemonSet ⽽⾮ReplicaSet。 这些Pod的⽣命周期与机器 的⽣命周期相关：在其他Pod启动之前，这些Pod需要在机器上运⾏；当机器准备重启/关闭时，可安全终⽌这些Pod。

Install Cilium Install Cilium as DaemonSet [https://kubernetes.io/docs/concepts/workloads/controllers/daemonset/] into your new Kubernetes cluster. The DaemonSet will automatically install itself as yaml first. Alternatively, it is possible to manually generate a YAML manifest for the Cilium DaemonSet and Hubble Relay/UI as follows. The generated YAML can be applied on top of an existing installation: --set hubble.ui.enabled=true > cilium-with-hubble.yaml # This will modify your existing Cilium DaemonSet and ConfigMap kubectl apply -f cilium-with-hubble.yaml The Cilium agent pods will be restarted
