How to implement Devops with automation tools ｜ including low code and Devops application practice

author ：Tiger Wang, Head of cloud intelligence research and development & Open source project  FlyFish PMC.

This article will be from 5 Explain in detail how to use automatic tools to land DevOps. First of all, I will introduce the disadvantages of the traditional iteration method and why it is introduced DevOps; We'll talk about it next DevOps Advantages of iterative approach , And how to use automated tools DevOps; The next two chapters focus on how to control DevOps Key links in the landing process, low code technology and DevOps Some new explorations .

Disadvantages of traditional iteration

In the way of daily work iteration , The development team carries out the development design and the construction of the overall system , Therefore, the system needs to be updated iteratively ; The operation and maintenance team tests the development team code Deploy online , That is to ensure the stability of the system 、 Safe operation . thus , The two teams will cause the following disadvantages through traditional iteration ：

• Team independence ： The work of the development and operation and maintenance team , It's independent of each other .  We seldom communicate with each other before , I don't know each other's work ;

• Prone to sudden problems ： Manually deploy the code , Prone to human error , Seriously, it may cause damage to the production environment ;

• Cycle extension ： The development and operation and maintenance teams have their own rhythms , The two teams are out of sync , As a result, it is difficult to finish online on time .

Next , We will combine the actual scene , Show the problems and pain points encountered in the iteration process .

• The operation and maintenance team needs to tidy the containers 、 Documentation of cluster and other related deployments , But because I don't know the architecture of services 、 Dependence , As a result, the arrangement of deployment documents becomes complicated ;

• Because the operation and maintenance students are not clear about the internal logic of the application , As a result, the normal operation of the application cannot be judged independently ;

• The operation and maintenance team knows nothing about the progress of the development team , The operation and maintenance team makes the monitoring plan according to their own understanding ;

• The same product 、 The same environment , Manual deployment is required every time , Too much repetitive work ;

• Simple installation and deployment , Service update , But it still needs personnel input . Excellent people are unwilling to do it , Ordinary people are not at ease . There is no room for growth .

DevOps Iterative approach and advantages

DevOps It is to promote the cooperation between the development and operation and maintenance teams , Deploy code to production environments faster in an automated and repeatable way , During the daily iteration , It has the following advantages ：

• Predictability ：DevOps The unexpected failure rate of the new version is greatly reduced ;

• Reproducibility ： Versioning all content , So that the previous version can be restored at any time ;

• Maintainability ： When the new version crashes or has problems , Easy rollback ;

• cost reduction ：DevOps It improves the efficiency in the development process , Reduced R & D costs ;

• Higher quality ： Due to close cooperation with the operation and maintenance team , Product problems should be exposed as soon as possible ;

• Reduce risk ：DevOps The content of risk control is added in the link , Reduce project R & D risks .

Landing with automatic tools DevOps

Introduction to common automation tools

In daily work , The commonly used automatic chemical industry has JIRA、Gitee、sonarQube、Jenkins、Docker、JFrog, In addition, low code data visualization platform FlyFish It is also an indispensable part .

• JIRA
   
  ：
    It is mainly used for defect tracking 、 Customer service 、 Demand collection 、 Process approval 、 Task tracking 、 Work areas such as project tracking and agile management ;

• Gitee：
    Used for warehouse and branch management , Code scanning 、 Vulnerability checking, etc ;

• sonarQube：
    adopt PMD、CheckStyle、Findbugs Such as code rule checking tools to standardize code writing ;

• Jenkins：
    Mainly used for continuous or automatic construction / Test software project , And monitor some regularly executed tasks ;

• FlyFish
   
  ：
    Open source low code visualization tool , A large visual screen can be formed by dragging , Used for process Kanban construction ;

• Docker：
    Put the running environment and configuration into the code and deploy ;

• JFrog：
    For managing build tools ( Such as ：maven、gradle) And so on , In order to manage third-party libraries and publish target version libraries , So as to improve the efficiency of software development .

Automatic tools landing DevOps Workflow

Management through JIRA Establish development tasks , And assign developers to build the code , Use this to track tasks ; Developers push the code to Gitee Submit , Use after submission Gitee The corresponding webhook Push to Jenkins;Jenkins After receiving the notification, you can pull the branch code , And notify the corresponding sonarQube Conduct code scanning ; After scanning , Relevant personnel can see the code scanning quality results , At the same time, it can be partially built and mirrored ; After the code is built, it will be pushed to Docker Mirror image , At the same time, it can also be put into JFrog in , Developers can pull directly without repeated construction .

Automatic tools landing DevOps The overall workflow is through Jenkins Notify the server to pull the image , Build after pulling , When the build is complete, pass FlyFish Visualizing .

How to control key links

• adopt JIRA After the task is established , Through the built-in dashboard, you can view the code of the specified developer BUG Number , So as to accurately locate personnel problems , Make management improvements ; On the other hand , It can be shown in the instrument cluster under different stages BUG Quantity optimization of the overall development process ; Besides , The task development progress can be controlled through the task number Kanban interface .

• adopt Gitee You can view some operations after pulling the code Branch , Including whether the code is timely merge、 Whether the branch is submitted in time 、 Whether the scanned code has vulnerabilities or defects 、 Some situations of the pipeline after construction , This cycle ensures that the branch can run healthily .

• adopt Docker Disk that can monitor code runtime after deployment 、 Memory consumption , So as to ensure the normal operation of the code .

• adopt FlyFish The Kanban large screen created monitors the health of each workflow . Including operations 、 monitor 、 plan 、 Development 、 compile 、 test 、 Release 、 Deployment and so on .

Low code technology and DevOps Explore

future , Low code technology and DevOps There will be more possibilities . Including the way to probe the low code Jenkins Control key indicators ; Process arrangement , Including event triggering 、 Inform the staff . Abstract script 、 Abstract objects 、 abstract action, Arrange the tasks ; Data connection , Get through with low code DevOps Process application , Easily quantify the indicators in the process .

• And JIRA Combine to create task quality Kanban .

• And Gitee Combine to create code engineering Kanban .
