阿里云 ACK Pod重启：pod was OOM killed

原因为：limits和requests的值设定为一样的了，

pod request达到了limit限制，kubelet会统计到request＋缓存就超限，然后触发自动重启

 resources:
            limits:
              memory: 4Gi
            requests:
              memory: 4Gi

调整为

 resources:
            limits:
              memory: 4Gi
            requests:
              memory: 2Gi

　　

注意：java应用配置xmx和xms时，值建议为limit的 85%
