If you include the localhost IP address (127.0.0.1, or ::1) with the publish flag, only the Docker host and its containers can access the published container port. $ docker run -p 127.0.0.1:8080:80 -p '[::1]:8080:80' nginx Warning Hosts within the same L2 segment (for example,...

主要的模块有:Docker Client、Docker Daemon、Docker Registry、Graph、Driver、libcontainer以及Docker container。1、docker client docker client 是docker架构中用户用来和docker daemon建立通信的客户端,用户使用的可执行文件为docker,通过docker命令行工具可以发起众多管理container的请求。
)在 Dockerfile 中,您也需要指示 Docker 接聽您會在執行階段使用的 TCP 通訊埠 (本例中為通訊埠 80,如 EXPOSE 設定的設定)。 您可在 Dockerfile 中指定其他的組態設定,視您使用的語言和架構而定。 例如,ENTRYPOINT 行中有 ["dotnet", "MySingleContainerWebApp.dll"] 會指示 Docker...

总结:Linux Container是一种轻量级的虚拟化的手段。 Linux Container提供了在单一可控主机节点上支持多个相互隔离的server container同时执行的机制。Linux Container有点像chroot,提供了一个拥有自己进程和网络空间的虚拟环境,但又有别于虚拟机,因为lxc是一种操作系统层次上的资源的虚拟化。
container runtime: 负责镜像管理以及Pod和容器的真正运行(CRI); kube-proxy: 负责为Service提供cluster内部的服务发现和负载均衡;它运行在每个计算节点上,负责Pod网络代理。定时从etcd获取到service信息来做相应的策略。它在Node节点上实现Pod网络代理,维护网络规则和四层负载均衡工作。
