Phenomenon: A running pod restarts too many times in a short period of time
How to locate the problem: View pod logs
kubectl get event #查看当前环境一个小时内的日志
kubectl describe pod pod_name #查看当前pod的日志
kubectl logs -f pod_name --previous #查看重启之前的那一次pod的日志，从那一刻开始计算
###############
一般用以上的三个命令就行This time using the following command solved the problem
kubectl describe pod pod_name Cause of the problem: OOM, pod was killed and restarted ( not enough memory )
View the deployment.yaml file of the service
It was found that our deployment.yaml has restricted the memory usage of the service.
Solution: Increase the memory value of limit, then delete -f yaml, and then apply -f yaml
It’s not easy for newcomers to create. If you think it’s good, please give it a thumbs up! ! !
