1、新建命名空间,在该命名空间中创建一个pod
命名空间名称:cka
pod名称:pod-01
镜像:nginx
kubectl create ns cka vim pod-01.yaml apiVersion: v1 kind: Pod metadata: namespace: cka name: pod-01 labels: app: pod-01 spec: restartPolicy: Always containers: - name: pod-01 image: nginx imagePullPolicy: IfNotPresent kubectl apply -f pod-01.yaml2、创建一个deployment并暴露Service
名称:alibaba-666
镜像:nginx
kubectl create deployment alibaba-666 --image=nginx kubectl expose deployment alibaba-666 --type=NodePort --port=80 --target-port=80 --name=alibaba-6663、列出命名空间下指定标签pod
命名空间名称:kube-system
标签:k8s-app=kube-dns
kubectl get pod -n kube-system -l k8s-app=kube-dns
