1. kubeadm knowledge map Kubeadm is a tool to implement the k8s environment quickly. Also you don’t need to care about the configure environment, just know how to bootstrap it. Master the basically command to use kubeadm.
2. Kubeadm practice 2.1 The practice environment Google cloud instance
Linux system.
2.2 Environment configure Install container (Docker)

Part 1: For this part, comprise of the basic knowledges including Cloud history, container technology and k8s etc.
1. Cloud Technology 1.1 The History Of Cloud computing https://skyao.io/learning-cloudnative/introduction/history.html
IaaS: Infrastructure as a service
PaaS: Platform as a service
SaaS: Software as a service
1.2 Cloud Native https://skyao.io/learning-cloudnative/introduction/background.html
1.3 DevOps And Strengths https://www.qikegu.com/docs/4262

2. Container Technologies 2.1 Virtualization Technology Virtualization refers to the act of creating a virtual version of something, including virtual computer hardware platforms, storage devices, and computer network resources etc.
1. Background Up to now, perhaps you haven’t had to pass any kind of configuration data to the apps. Because almost all apps require configuration, which shouldn’t be baked into to the built app itself. This article shows two ways to pass the configuration data to the apps.
2. Secret Secret is for the information you’ve passed to the containers is sensitive. K8s provides a separate object called a Secret. There are 4 ways to create the Secret.
1. Background We always deploy the final version applications to the production env. There are several ways to ensure the release production stably and safety. Below sections are k8s deployment strategies.
2. The Strategies There are 4 ways to do the production release. 1) Rolling-update. 2) Recreate. 3) Blue/Green. 4) Canary. Below is the details.
Recreate Update
This is very clumsy way to update. Destory V1 application then create V2 application.
C++ Learning Notes. 1. Knowledge Map. Architecture Program Language classification.
Generic Programming
K8S network is divided into 3 levels. From inside to outside, there are 3 types: 1) Container Network. 2) Intra-Cluster Network. 3) External Cluster Network. Below is the details,
1. Container Network Docker networking is limited within the host itself. By default, it creates a virtual bridge named docker0 and for each container it allocates a virtual ethane which get attached to the bridge docker0. So, in Docker two containers can communicate with each other if they resident on the same host.
