Design and implementation of continuous integration/technical delivery full-process pipeline tools
Overview
With the continuous iteration of software development, code version control, construction, testing, delivery and other tasks are becoming more and more complex. In order to achieve efficient team collaboration and quickly deliver high-quality software products, continuous integration/technical delivery tools have gradually become indispensable tools.
The design and implementation of continuous integration/technical delivery full-process pipeline tools were created to solve these problems. It can help the development team automate code version control, construction, testing, delivery and other tasks, improve development efficiency, reduce the probability of errors, and ultimately achieve fast and high-quality software delivery.
This article will introduce the design and implementation of a continuous integration/technical delivery full-process pipeline tool based on Jenkins, including the tool's architectural design, main functional modules, usage methods, etc.
Tool architecture design
This tool uses Jenkins as the core technology and automates the entire process of code from version control to delivery by building a Jenkins pipeline. The specific tool architecture is as follows:
As shown in the figure, the main modules of this tool include code warehouse, Jenkins server, build server, test server, production server and monitoring platform. Among them, the code warehouse is used to store source code, and you can choose open source code hosting services such as GitHub and GitLab; the Jenkins server is used for the scheduling and control of automated pipelines, and tasks such as construction, testing, and delivery are all completed on the Jenkins server; the build server is It is used for code compilation and packaging; the test server is used to perform automated testing and generate test reports; the production server is used to deploy and release software products and provide online services; the monitoring platform is used to monitor the running status and log output of each server in real time .
Main functional modules
The main functional modules of this tool include:
Code library
As the source of continuous integration/technical delivery, the code base is the foundation of the entire automated pipeline. Code repositories are generally divided into two types: open source code hosting services and private code repositories. Common code hosting services include GitHub, GitLab, Bitbucket, etc. These services provide rich APIs and Webhooks, and can be easily integrated with Jenkins.
Jenkins pipeline
Jenkins pipeline is the core technology of this tool. The Jenkins pipeline can automate the entire development cycle and automate the entire process of continuous integration/technical delivery. Through the pipeline, developers can automate the entire process of code from version control to delivery, greatly improving development efficiency.
There are many types of Jenkins pipelines, including multi-branch pipelines, single-branch pipelines, pipeline pipelines, multi-stage pipelines, etc. Developers need to choose the pipeline type that suits them based on specific needs.
code build
Code building refers to the process of compiling source code into executable code. Construction work usually includes compilation, packaging, static checking, code obfuscation and other processes.
In Jenkins, code construction can be achieved through tools such as Maven and Gradle. Build tasks can be configured in Jenkins to automate the build process.
automated test
Automated testing refers to the automated execution of tests through software tools to find errors or defects in software applications. Automated testing can greatly reduce the workload of manual testing and improve testing efficiency.
In Jenkins, automated testing can be implemented through plug-ins, including JUnit, Selenium, JMeter, etc. You can configure test tasks in Jenkins, automatically run test cases, and generate test reports.
product deployment
Product deployment refers to the process of deploying software products from a test environment to a production environment. The deployment process usually includes software package upload, deployment script execution, data migration and other processes.
In Jenkins, product deployment can be achieved through plug-ins, including SSH, Deployer, Ansible, etc. Deployment tasks can be configured in Jenkins to automate the product deployment process.
Monitoring alarm
Monitoring and alarming refers to monitoring the running status and log output of the server in real time through the monitoring platform, and automatically sending alarm information when a fault or error occurs, so as to handle the problem in a timely manner and ensure the stability of the service.
In this tool, the monitoring platform can be implemented using open source tools such as Prometheus and Grafana. You can integrate monitoring alarms and Jenkins through monitoring plug-ins to monitor the execution status of the Jenkins pipeline in real time, and cooperate with the Jenkins plug-in to realize the automatic termination and alarm functions of the pipeline.
Instructions
How to use this tool includes the following steps:
Step 1: Install Jenkins
Before using this tool, you need to install Jenkins. Jenkins can be downloaded from the official website or installed on Docker. After the installation is complete, you need to install some necessary plug-ins, such as Git, Maven, Gradle, etc.
Step 2: Create a Jenkins pipeline
Create a new pipeline task in Jenkins, and you can choose different types of pipelines such as multi-branch pipelines, single-branch pipelines, pipeline pipelines, and multi-stage pipelines.
Configuring information such as code libraries, build tasks, test tasks, deployment tasks, etc. in the pipeline can be achieved through Jenkins integrated plug-ins.
Step 3: Configure monitoring alarms
Configure the monitoring plug-in in Jenkins to integrate the monitoring platform and Jenkins to realize real-time monitoring and alarming of the pipeline.
Step 4: Get started
After completing the above steps, you can start using this tool. Through the Jenkins pipeline, code version control, construction, testing, deployment and other processes can be automated.
Summarize
The design and implementation of continuous integration/technical delivery full-process pipeline tools can help development teams automate code version control, construction, testing, delivery and other tasks, improve development efficiency, reduce the probability of errors, and ultimately achieve fast and high-quality software delivery.
