Ingress network is an open-source library for android Network Communication Based on jmdns and netty, and ingress networkjmdns
Currently, many open-source network communication libraries for android are mostly based on http, such as Volley and android-async-http. network communication over the WAN is a good solution, for LAN communication scenarios, the above-mentioned http-based network communication is st
Kubernetes about the service exposure is mainly through the Nodeport way, through the binding minion host of a port, then the pod request forwarding and load balancing, but this way the defect is
The service may have many, if each is bound to a node host port, the host needs to open the perimeter of a heap of ports to make services calls, management confusion
Cannot apply firewall rules required by many companies
The ideal way is through an external load balancer, binding fixed

Service Discovery and load balancing
Ingress Combat
First, service discovery and load balancingIn the previous installation deployment Kubernetes cluster, it was simple to demonstrate that pod and Service,kubernetes implemented service discovery and load balancing for containers within the Kubernetes cluster through service resources. Service is one of the Kubernetes services discovery and load balancing.
This paper introduces the use of Ingress combined with Traefik to realize the dynamic and static separation of the inlet, this article will implement the ingress HTTPS configuration based on the previous text.For simplicity and efficiency, it is recommended that HTTPS offload be implemented at the ingress level after containerized deployment is applied. Popular p
The Linux kernel implements a data packet queue mechanism, which works with a variety of queuing policies to achieve perfect traffic control and Traffic Shaping (hereinafter referred to as traffic control ). Traffic control can be implemented in two places: egress and ingress. egress is the action trigger point before the data packet is sent, while ingress is the action trigger point after the data packet i
ObjectiveIngress is a way to expose the internal service of a k8s cluster, and user-edited profiles define a ingress resource to enable external network access to the intranet service.Ingress Controller is to manage all Ingress objects, ingress controller inside is actually an nginx container, when Ingress controll by
1, Ingress Components Introduction
Ingress solves the problem of the domain name and service after the new service is added, basically a Ingress object, which is loaded by creating and updating with Yaml.
Ingress Controller is to ingress this change to generate
Services deployed by users on Kubernetes typically run on private networks, and pod and service provide parameters such as Hostport,nodeport to expose these service ports to K8S nodes for user access. There are obvious drawbacks to this approach:1) Easy to occupy excessive host port;2) service ports exposed to multiple hosts increasing the difficulty of firewalls and security configuration3) The default hostport,nodeport mode does not function as load balancingK8s's
Linux TC ifb principle and ingress flow control, ifbingress
First, paste the annotation of the ifb. c file header of the Linux kernel:
The purpose of this driver is to provide a device that allowsFor sharing of resources:1) qdiscs/policies that are per device as opposed to system wide.Ifb allows for a device which can be redirected to thus providingAn impression of sharing.2) Allows for queueing incoming traffic for shaping insteadDropping.The origin
limitations of the TC itself, in fact, you can fully implement a queue mechanism on the Ingress point, said TC control is not controlled only because the Linux The current implementation of TC does not implement the ingress queue.Linux has a lot of hooks on the stack, NetFilter of course is the most obvious, it can not only implement firewalls and NAT, can also be a packet on the prerouting Hook point queu
the container as long as the network between the pod can be interconnected to call each other, a small number of low-level services need to expose the HTTP port. Platform services need to expose HTTP ports externally.
The nginx rule of static and dynamic separation is mainly the above two categories, in which the number of platform services is mostly, and the bottom service has less static and dynamic separation rules.

[TOC]DescriptionThere is no detailed explanation of the Kubernetes's service exposure and Traefik's principles. The Traefik principle can be consulted in the official documentation: https://docs.traefik.io/, This document can also be consulted about the service exposure of kubernetes and the rationale for using Traefik as a kubernetes ingress: https://mritd.me/2016/12/06/ Try-traefik-on-kubernetes/.

All qdiscs discussed so far are egress qdiscs. each interface however can also have an ingress qdisc which is not used to send packets out to the network adaptor. instead, it allows you to apply tc filters to packets coming in over the interface, regardless of whether they ha
