二、核心实战

1.操作namespace

kubectl create ns hello
kubectl delete ns hello

#yaml
apiVersion: v1
kind: Namespace
metadata:
   name: hello

2.pod:运行的一组容器，pod是kubernetes中应用最小的单位

3.k8s运行pod

kubectl run mynginx  --image=nginx
yaml::::::
apiVersion: v1
kind: Pod
metadata:
     labels:
        run: mynginx
     name: mynginx
spec:
    containers:
    - image: nginx
       name: mynginx

4.查看pod运行日志

kubectl logs pod

5.查看k8s分配的pod的ip是多少

kubectl get pod -owide

6.进入容器里面修改

kubectl exec -it mynginx -- /bin/bash
