pod

示例

# 创建
[rancher@master1 test]$ kubectl create -f pod.yml
pod/myapp-pod created
# 查询
[rancher@master1 test]$ kubectl get pod -o wide
NAME        READY   STATUS    RESTARTS   AGE
myapp-pod   1/1     Running   0          8s
# 查询json
[rancher@master1 test]$ kubectl get pod -n demo myapp-pod -o json |less
# 查询详细
[rancher@master1 test]$kubectl describe pod -n demo myapp-pod
# 获取被创建时的yml文件内容
[rancher@master1 test]$ kubectl get pod -n demo myapp-pod -o yaml
# 删除
[rancher@master1 test]$ kubectl delete -f .
pod "myapp-pod" deleted
# 创建和更新，apply大法好
[rancher@master1 test]$ kubectl apply -f .
pod/myapp-pod created
# edit更新，如果只更新标签，那么元数据里的标签不会更新，，所以一般不用这种方法，除非要改全改了
[rancher@master1 test]$ kubectl edit pod -n demo myapp-pod
# patch替换，比较麻烦，效果跟edit一样
[rancher@master1 test]$ kubectl patch pod -p '{"metadata":{"labels":{"app":"pod-nginx"}}}' myapp-pod -n demo
pod/myapp-pod patched
