kubectl get deploymentshows the desired and updated number of replicas, the number of replicas running, and their availability. As mentioned previously, we can use the kubectl describe command to a complete picture of the deployment. Copy kubectl rollout status deployment nginx-deployment kubectl get ...
Deploying the Kubernetes Deployment YAML with Containerd To deploy the Kubernetes Deployment YAML with Containerd, you need to apply the YAML file using thekubectlcommand-line tool. Make sure you have a running Kubernetes cluster and thekubectltool installed. kubectl apply-fdeployment.yaml 1. The co...
如果实际状态和期望状态存在差异,控制器会进行操作确保kubernetes资源/对象处于期望状态。 假设您想要创建一个Deployment,您可以在YAML中指定它期望的状态,比如,2个副本、1个卷挂载、configmap等。内置的controller将确保Deployment始终处于期望的状态。如果用户将副本数更改为5,Controller将感知这个变化,并保证Deployment的副本...
} Let's consider the following yaml deployment using the nodeSelector of pool name: # app-deploy.yamlapiVersion:apps/v1kind:Deploymentmetadata:labels:app:app-deployname:app-deployspec:replicas:100selector:matchLabels:app:app-deploytemplate:metadata:labels:app:app-deployspec:containers:-image:nginx...
spec.names.kind:Defines the kind of CR that can be created using the CRD. Like **Deployment**,**CronJob**,**CronTab**. spec.scope:Defines what is the scope of the CR. It can either be set to 'clustered' or 'namespaced'. It is set to 'namespaced' by def...

在这里,您可以看到我在容器外部公开端口 8080 和 5556。这里很重要的一点是 volumeMounts 部分。mountPath 使用 configmap 作为卷。它覆盖容器默认的 /app/config.yaml。现在我们 apply 一下: kubectl apply -f app-deployment.yaml 查看monitoring 命名空间中的 Deployment。
使用yaml 创建后,通过命令行能够看到 service 的信息如下,可以看到 NodePort 类型的 service 也存在一个 ClusterIP。图14 NodePort 类型 service 的命令行信息*(图片来源于参考文章)*所以,针对于 NodePort 类型,其使用场景就是在 k8s 集群外通过 node ip 来访问集群内的服务。
