kubernetes Introduction
Kubernetes is a container cluster management system that Google Open-source in June 2014, using the Go language development, Kubernetes also called k8s.
K8s is a Borg container cluster management system inside Google, Borg has been operating on Google's mass production for 10 years.
K8s is mainly used for automated deployment, expansion and management of container applications, providing a set of functions such as resource scheduling, deployment management, service disc
The content of this article has been validated based on k8s v1.8.8. K8s Service defines the access entry address of a server, the front-end application accesses a cluster of pod replicas behind it through this entry address, and the access requests from outside are load balanced to each container application on the back end. Between the service and the back-end pod replica cluster, the docking is done throu

In the Iptables table, you can see the "kube-svc-" and "kube-sep-" chains that are created in the NAT table and the rules in those chains by Iptables-save, and here are examples of these rules:
If there is more than one pod on the back end of a service, as you can see in the Iptables table by Iptables-save, here is an

How to download and install Cocoapods.
1. Use Taobao's ruby image to access the cocoapods. Click the command in the terminal in the following order:
$ gem Sources--remove https://rubygems.org/
Wait until you have a response, and then typed the following command
$ gem sources-a https://ruby.taobao.org/(Note is HTTPS)
In order to verify that your ruby image is and is only Taobao, you can view it with the following command:
$ gem sources-l
Only the following text appears in the terminal to indicate

It calculates the difference between the state that the user wants to reach and the current state, and then sends a request to Apiserver via clients to drive the state evolution of the cluster to the user's requirements. The blue is the original client-go, red is the code that was filled in when you wrote the controller.

Master runs the Linux operating system, which can be either a physical machine or a virtual machine. To achieve high availability, you can run multiple master.NodeNode's job is to run the container app. Node has ma

Fourth Step: Install Cocoapods

Enter the following command in the terminal to complete the installation:

The essence of swarm and k8s are container orchestration services.They can abstract the underlying host, and then start the application from a built-in image and eventually deploy it to a host on a docker basis. Which scenario should be chosen as our container cloud service? I think k8s (kubernetes short) and swarm compared to MySQL and SQL Server comparison, the former lightweight, implementation fast, in order to achieve core functions, more suitable for small-scale deployment, the latter is e
Deployment advantages relative to RCRS and deployment are mainly used to replace RC. RS is all called Replica Set. The advantages relative to rc,rs and deployment are as follows:
RC only supports equation-based selector, such as Env=dev or ENVIRONMENT!=QA. However, in RS, a new set-based selector, such as version in (v1.0,v2.0) or env not in (DEV,QA), is also supported. This brings convenience to complex operations management.
Upgrading the pod

Original: How to Create CocoaPods with Swift
You may be familiar with some of the more famous open-source cocoapods frameworks, such as Alamofire, Mbprogresshud. But sometimes you may not find the pod that just meets your needs, or you need to split a large project into smaller, reusable components.
Fortunately, creating your own cocoapods is an easy thing to do.

Mode one: Use USB data cable to connect with computer:
In order to let the Pea Pod Cell Phone wizard correctly identify your mobile phone, you need to turn on the phone's USB debug switch, the following steps:
