一个Deployment 控制器为 Pods 和 ReplicaSets 提供声明式的更新能力。 你负责描述 Deployment 中的 目标状态,而 Deployment 控制器以受控速率更改实际状态, 使其变为期望状态。你可以定义 Deployment 以创建新的 ReplicaSet,或删除现有 Deployment, 并通过新的 Deployment 收养其

在该例中:将创建名为 nginx-deployment 的 Deployment ,由 .metadata.name 字段指示。 Deployment 创建三个复制的 Pods,由 replicas 字段指示。 selector 字段定义 Deployment 如何查找要管理的 Pods。在这种情况下,只需选择在 Pod 模板(app: nginx)中定义的标签。但是,更复杂的选择规则是可能的,只要 Pod 模板本...
它和Pod之间的关系如下图,即Deployment通过ReplicaSet来管理Pods。 metadata.name: simple-http-deployment用于描述该Deployment组件名。它还有一个重要作用,就是Pod的名字也是基于它生成的。 spec.replicas: 2表示我们将维持两个Pod的副本。 spec.selector.matchLabels.app: simple_http用于描述维持的Pod副本的匹配...
You can use workload resources to create and manage multiple Pods for you. A controller for the resource handles replication and rollout and automatic healing in case of Pod failure. For example, if a Node fails, a controller notices that Pods on that Node have stopped working and creates a...

通过kubectl get pods命令查看kube-system命名空间下新建的kube-proxy-worker容器(如果您使用专有版集群,还需查看kube-proxy-master)是否为Running状态。 通过kubectl logs命令查看新建容器的日志。 如果出现Can't use the IPVS proxier: IPVS proxier will not be used because the following required kernel modules ...
In Kubernetes 1.26, label selectors are verified for HPAs. When multiple HPAs point to the same collection of pods or Deployment, the HPAs do not take effect and an AmbiguousSelector event is generated. In Kubernetes 1.26, when multiple StorageClasses are specified as default StorageClasses by...
Deployment unit in k8s is pod. Pods are a model of the pattern of multiple cooperating processes which form a cohesive unit of service. They simplify application deployment and management by providing a higher-level abstraction than the set of their constituent applications. Pods serve as unit of...
