镜像在本地可以正常启动，放到阿里云之后无法启动，只在容器启动的一瞬间
状态是oomkilled的然后无限重启容器，oomkilled状态只维持一会姑没有截图
阿里云edas配置使用cpu和内存的资源，在开发更新代码之前项目一直稳定正常运行
#启动脚本 [root@deploy-nb-63 nuxt_talent_mobile]# cat run.sh #!/bin/sh cd /nuxtjs && npm run start:test
阿里云ack检测到的报错

以上node的报错发送给开发没有排查出任何错误
#在本地测试服务器修改启动脚本然后手工启动正常，推送到阿里云手工测试 [root@deploy-nb-63 nuxt_talent_mobile]# cat run.sh #!/bin/sh #cd /nuxtjs && npm run start:test tail -F /nuxtjs/start.js
#手工启动node，非常正常
#在次测试在阿里云ack直接进入pod手工启动，进入node服务器进入容器内手工执行npm run start:test启动node
#根据ack上面查看到的名称和对应的节点ip在对应的node节点找出容器
#进入到node服务器
#查找出所在的容器
#进入到pod
#手工启动node

#最后发现这样无法排查出错误，并且把日志发送给开发，开发也找不到原因，所以在本地测试服务器用docker stats查看容器启动的时候所占用的资源
发现启动过程中cpu资源最高去到了300%，内存最高去到了3g多
#启动后资源占用率下降，CPU维持在0.01核，内存维持在923.4MB
最终发现是开发代码没做优化所造成启动一瞬间资源占用过高，造成无法启动，只能调整阿里云k8s集群pod的内存和cpu资源限制
调整之后pod正常启动，但让开发优化代码
