2020jenkins study notes

background

​ DevOps In fact, the description is from the developer push Code or call online tag When the new version was released , Will go through a series of unit tests , Integration testing , A series of steps such as automatic deployment are transformed into an automated process . As long as these automated scripts are ready , Then it saves a lot of material and financial resources . Programmers only need to care about their business code , There are a few cumbersome things behind , pack , Don't worry about updating the image , There is no need to care , Because the process is the same , The steps are the same , Just let the script do it for us .

​ Then let the script do it for us , Many friends said , Simple , Write your own shell Script or python The script is done . Hey , A simple project is a team of several people python The script can also cope with it, no problem . however , More than one , More projects , Your script is written differently for each project , I have to start over . It's no problem to build a small house by yourself and ask a few workers to dig the ground manually , If you want to build high-rise buildings, you can dig soil by hand ? Then you must find an excavator . The excavator here is Jenkins 了 , Ready made CI/CD Open source solutions , Just use it . And many people are using , Big guys write code bug Less than you write and stronger . Have a problem , Go to the community , Just search the official website . Not enough function ? Can install jenkins plug-in unit , It basically meets your regular needs , I really didn't think about it anymore jenkins Insert your own unique script .

Content

Jenkins The working principle and content of vernacular :

​ Yours jenkins What's the name of the project , What project did ( Project description ), How do you build , Where to pull the code , After pulling the code , What programming environment do you want to be in , How to execute any command operation on the code , What are you going to do after the operation ( Send an email to inform ? Call the deployment interface ? wait ).Jenkins WebUI That's the interface , Like filling in the blank , I have set up the general framework for you , Just fill in the things you need .

​ But we won't go to see it every time Jenkins WebUI To trigger our build ? Still not automated enough . that Jenkins Pipeline It's coming out. , Jenkins Embedded Goovy virtual machine , As long as you write Goovy Script combination Jenkins Built in variables and functions , Can realize script Automation . and Openresty cut from the same cloth , stay nginx Middle if LuaJIT virtual machine , In this way, you can maximize the freedom to realize your needs .
