原因	根据上面的提示，是当前的nodes CPU资源不足 所引起创建pods失败！
解决办法	1: 给nodes 增加cpu 资源 2：针对nodes 回收没用的pods
增加nodes资源后   问题解决！	# kubectl top nodes NAME      CPU(cores)   CPU%   MEMORY(bytes)   MEMORY%    node1   163m         4%     5116Mi          66%        node2   91m          2%     5191Mi          67%        node3   97m          2%     4575Mi          59%          # kubectl get pods -n ms  NAME                       READY   STATUS    RESTARTS   AGE product-5cb556b9f4-pg78s   1/1     Running   0          20m stock-9cb4758b5-6mwfm      1/1     Running   0          71m #
