Shulou(Shulou.com)06/03 Report--

Hello, bloggers of 51CTO and colleagues of IT.

I am Wu Guangke teacher, I am very glad to be here with you to exchange IT technology, unwittingly in the IT operation and maintenance industry has been engaged in nearly 10 years.

He has served as an architect and manager of Linux operation and maintenance in state-owned enterprises, JD.com, Yixin and other first-line Internet companies, a senior lecturer of Linux in 51CTO College, and served as the moderator of Linux, a number of well-known communities in China.

Good at system high concurrency, more than 10,000-level server maintenance, server performance tuning, enterprise security operation and maintenance, Openstack, Docker, KVM and Kubernetes cloud computing, automatic operation and maintenance and other core technical fields. Long-term engaged in state-owned enterprise organs, picture bar, Yixin, JD.com Mall and other well-known enterprises 10 million, hundreds of millions of levels of PV portal maintenance work.

I was born in a poor mountain village in Guizhou Province. From an early age, I experienced a simple life of chopping firewood, herding cattle, carrying water, cooking, working at sunrise and returning from sunset. I saw that my parents had been in a small mountain village all their life and had never seen a big city. so from an early age, I was determined to get out of the mountains and let my parents live a happy life!

It is such a belief that I keep working hard. Since I graduated from university, I have been working on the IT operation and maintenance of "Beijing drifters" for nearly 10 years. Along the way, I have received a lot of careful guidance and patient help from my predecessors and dignitaries. I have learned that a person should not only live for himself and his family, but also to help more people through his own ability.

Today, with the help of the 51CTO blog platform, I am very honored to share my experience in the BATJ front-line Internet with you. I hope that in the future, we will cheer together. I hope the technology shared by Mr. Wu can make you take fewer detours, make you become the god of operation and maintenance more quickly, easily break through the monthly salary of 10KBG, and marry Bai Fumei!

With the development of IT industry today, it has developed from traditional technology and traditional operation and maintenance to mainstream technology and automated operation and maintenance. Mastering the core technology in the future is the key factor to catch up with the changes of the times and widen the gap with others.

This column will completely analyze and practice the three mainstream IT technologies: virtualization, cloud computing, and one of big data's virtualization technologies. Let everyone master the core technology of the enterprise and lay a solid foundation for their own appreciation and salary increase, so how can we learn Docker virtualization technology well?

Mr. Wu will analyze Docker concept, Docker principle, Docker configuration and deployment, Docker optimization, Docker command actual combat, Docker network, Docker production environment case, Docker image production, Docker container deployment, Docker warehouse, Docker monitoring, Docker-CI/CD integration, Docker troubleshooting and other aspects of brand-new analysis and practical Docker virtualization technology, so that you will fall in love with Docker virtualization technology.

Through the explanation of the following 20 chapters, you can really master Docker virtualization technology from 0, which are described in detail as follows:

Chapter 1: in-depth analysis of the concepts and differences of KVM, ESXI, XEN & Docker virtualization, in the era of virtualization technology everywhere: it is necessary for us to understand the advantages and disadvantages of each virtualization and make long-term planning in the production environment.

Chapter 2: in-depth analysis of the underlying implementation of LXC&Cgroup&Docker technology, in order to fundamentally master Docker, we need to dig deep into the core components of Docker technology, such as LXC, Cgroup, AUFS and so on.

Chapter 3: in-depth analysis of the principle of Docker virtualization image & engine architecture, the core of Docker technology is Docker container, while Docker container is based on the underlying image, skillfully master the nature of image, and can better manage and maintain our container.

Chapter 4:Ubuntu, CentOS6 and CentOS7 practical Docker latest stable version, the current mainstream operating systems are: Ubuntu, CentOS6, CentOS7, this chapter will take you from 0 to host device configuration selection, capacity planning, starting from 0 to build Docker virtualization platform in the way of production environment.

Chapter 5: production environment Docker essential 30 + actual combat command operation drill, Docker does not have graphical interface management by default. By being familiar with 30 + operation commands, you can maintain and manage Docker on a daily basis and improve your skills.

Chapter 6:Docker core underlying network actual combat analysis-production environment case use, the product of Docker virtualization technology is the Docker container, the container must be configured with the network to better navigate the Internet, in order to more LAN business systems associated.

Chapter 7: based on Docker-WEB automatic management of Docker containers, proficient in command-line operations, we can build a set of WEB management platform from 0, so that it is more convenient to manage and maintain Docker virtualization.

Chapter 8: build hundreds of Nginx and Tomcat WEB clusters based on Docker. The core of Docker virtualization lies in enterprise applications. If you only deploy and configure Docker virtualization platform without using it, it will not give full play to the value of Docker virtualization. This chapter will take you to apply Docker virtualization to the production environment from 0.

Chapter 9: how to build a LNMP+Redis cache enterprise architecture based on Docker and how to build a portal with millions of PV visits based on Docker virtualization? this article will use a specific case to reflect the lightweight performance of Docker virtualization, so that we are no longer afraid of architecture implementation and management.

Chapter 10:Docker Virtualization Image creation Secrets & SVN and GIT Image Update. The bottom layer of Docker Virtualization is Docker image. This chapter will give students an in-depth understanding of the image production principle, image production method and secret books, and submit the image to SVN and GIT repositories.

Chapter 11: based on the actual CentOS7 benchmark image of DockerFile, Dockerfile is the most practical method for creating Docker image. Mastering the syntax and strategy of Dockerfile, you can get twice the result with half the effort for making an image.

Chapter 12: based on DockerFile actual combat SSH, Redis, Nginx production images, based on Dockerfile, in addition to creating basic images of CentOS, you can also create various images of production environment, such as SSH, Redis, Nginx, Tomcat and so on.

Section 13: build SVN | GIT Warehouse platform & DockerFile Image submission Warehouse. Starting from 0, we will teach you how to build SVN and GIT repositories, so that our Docker images will have their own home from now on, and image updates will become simple and easy.

Chapter 14:Jenkins continuous integration platform & Dockefile&SVN | GIT is an one-stop operation. Docker images in production environment are updated frequently. Build Jenkins-CI/CD (Jenkins continuous integration) platform, which can implement version management and control of Docker images, making image production and update no longer difficult.

Chapter 15:Docker Image Repository Source Update-self-built Docker local high-speed sources, there are numerous Docker images in the production environment, which will cause confusion in management. If you use a public network repository, security, network problems and response efficiency will all be affected, so how to build a secure and reliable image repository becomes particularly important.

Chapter 16:Docker virtualizes the capacity expansion of CPU, memory and hard disk, and the isolation of resources becomes particularly important when Docker containers are used in the production environment. This article will focus on how Docker technology can achieve isolation and how to limit CPU, memory, hard disk, IO and bandwidth, so that our containers go their own ways and do not interfere with each other.

Chapter 17:Docker Virtualization Compose Enterprise production Environment practice, do you find that when Docker builds multiple architectures and services, there are too many commands to manage? It becomes more simple and convenient to manage multiple services and architectures through Docker compose.

Chapter 18:Docker production environment resource monitoring program & monitoring actual combat, the monitoring of Docker container resources is a necessary skill for our operation and maintenance, IT personnel, this paper will analyze the mainstream Docker monitoring scheme, and implement the monitoring of Docker resources.

Chapter 19: development of Docker virtualization platform management scripts based on SHELL programming, when we are proficient in daily management of Docker virtualization through the command line, is there a simpler, faster, batch management method, that is, we need to write SHELL management scripts, batch, 1000 + container maintenance, Docker container resources to generate reports, unified scheduling and management.

Chapter 20:Docker production environment common troubleshooting summary & case practice, Docker virtualization technology will encounter a variety of failures and errors in daily use, this chapter will summarize and practice Docker common 20 + failure cases, so that we no longer worry about the maintenance of Docker virtualization, let us fall in love with Docker virtualization technology, let us move towards high-paying jobs!
