模拟题目:
设置配置环境: [candidate@node-1] $ kubectl config use-context k8s
Task
将 deployment presentation 扩展至 4个 pods
参考:
kubectl scale deployment -h https://kubernetes.io/zh-cn/docs/tasks/run-application/scale-stateful-set/
解答:
考试的时候务必记住切换集群, 注意集群名称 kubectl config use-context k8s
#检查pod数量和运行情况
kubectl get deployments presentation -o wide
kubectl get pod -l app=presentation
#扩展数量
kubectl scale deployment presentation --replicas=4
检查:
kubectl get deployments presentation -o wide
kubectl get pod -l app=presentation
