A few weeks ago, we discussed advanced copy (modified to the cp command to display the copy progress bar ). One reader pointed out in the comments that other utility not only provides basic cp command functions, but also provides advanced functions not available in cp. Therefore, in this article, we will discuss a very similar command line tool-gcp.Gcp-advanced command line file copyer
According to the operation manual, gcp is an advanced command line
The Kubernetes network model is made up of four parts from inside to outside:
The network where the pod interior container resides
The network where the pod resides
Network for communication between pod and service
Network of communication between outside and service
It is recommended that you understand the network model of Docker before reading this article. Refer to the author's first two articles [

Both C2container Service (ECS) and Kubernetes (k8s) solve the same problem: spanning the host cluster Management container .

What is a container?Kubernetes is a container management platform. It is conceivable that we need containers to manage them. But what is a container? The best answers to the official Docker documentation are:
A container image is a lightweight, standalone, executable package that contains everything that can be run: Code, runtime, System tools, system libraries, settings. For Linux and Windows-based applications, containerized software can ru

2. Compile Steps
2.1 Clone Source Code
# git clone https://github.com/kubernetes/kubernetes.git
# git checkout release-1.7
2.2 To modify the source code is to solve the Gcr.io domestic problems, has been tested, even if ready to gcr.io related mirrors, such as not modify the source code will still be due to network problems caused the compilation failed
