Increase the number of concurrent executions
background
In the actual production process of the development team, Jenkins construction is often used, but the default number of parallel execution of Jenkins is only 2. If there are multiple tasks, it will need to wait, affecting the work efficiency
The solution
Modify the desired number of actuators, save
Jenkins triggers the downstream build
Select the build trigger
Triggered after other projects are built
The hello World Maven downstream subproject 1 will be built when the hello World Maven project is successfully built.
Downstream subprojects are automatically built, and if there are multiple downstream subprojects, the build is executed in parallel
Jenkins View View management
When a lot of jobs are created, it may be difficult for us to find one of our jobs. In this case, we can create views in Jenkins. The view of the job is similar to the folder on our computer. You can use certain filtering rules to filter existing jobs to the view or directly create jobs in the view.
- folder
- Folders are suitable for multiple teams sharing Jenkins
- Better performance and faster execution
- RBAC permission management is supported
- views
- The views are flexible and do not change the path of the job
- Views have a variety of forms, levels, kanban, assembly lines and other diversification
View mode
Folder mode
Jenkins plug-in management
Automatic plug-in installation
Installing plug-ins manually
In addition to the above automatic plug-in installation method, Jenkins also provided us with manual plug-in installation method. Especially in China, due to network reasons, sometimes we failed to install plug-ins by using the above method. Therefore, we can install plug-ins by downloading and uploading them.
The official download site is updates.jenkins-ci.org/
Source: domestic mirrors.tuna.tsinghua.edu.cn/jenkins/plu…
It is important to choose to download the version of the corresponding version, otherwise sometimes compatibility errors will occur.
Jenkins’ version can be seen at: Systems Administration — About Jenkins:
Manually uploading plug-ins
Overwrite plug-in directory
We can back up /var/lib/jenkins/plugins on a machine that already has Jenkins installed, upload the backup files to the Jenkins directory that we need to overwrite, and then restart Jenkins.
This method also gives us a faster way to install Jenkins. We can skip the initial plug-in installation and install it in this way.
Actual combat 1: Manually install plug-ins
Github API (1.114.2)
To domestic source: mirrors.tuna.tsinghua.edu.cn/jenkins/plu… *github-api*
Download it and install it manually. See the manual installation steps above
Actual combat 2: Manually install plug-ins
From here for a version of the plug-in installed automatically installing plugins, go to domestic source: mirrors.tuna.tsinghua.edu.cn/jenkins/plu…
