It is clear that the thread_proxy function is private internal and I do not expect that it would be mangled as "thread_proxy" because I actually do not need it mangled at all. In fact, in all my code that I had written and that runs on many platforms, I never

          kubernetes 架构 四层,如下: Client层:即Kubernetes集群外部用户、客户端等; 服务访问层:即由Traefik ingress实现服务发现、负载均衡和路由规则定义等; 业务应用层:即基于Kubernetes平台构建和运行企业业务应用,如CI/CD持续集成、微服务项目、监控告警和日志管理、私有镜像仓库等服务; 基础设施层:即由Kubernetes容器管理平台和Ceph/NFS数据持久化存储等系统组成的基础设施服务。 基础设施层 网络通信 :在容器和容器之间、容器和主机网络方面,可以使用 Calico 或Flannel等方案。 HA 高可用 :Kubernetes节点分为Master和Node两种类型节点,Master节点+HAProxy方案,Node节点模式具有天然的容灾冗余HA高可用 Docker 和操作系统优化 :如关闭swap内存交换分区,预留一定的CPU核数和内存资源给宿主机使用等。 Ceph/NFS 数据存储 业务应用层 镜像管理:使用Harbor私有镜像仓库服务; 日志管理:使用Elasticsearch、Filebeat 和 Kibana技术栈; 监控告警管理:使用Cadvisor、Prometheus和Grafana技术栈; 微服务架构:使用Service Mesh服务网格中的Istio方案; Devops
