[root@node-16 k8s]# 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 #
