Disabling the concurrency should limit the build to 1 build at a time. Just tried it. It just makes things much worse, because Jenkins sees a queue and then stacks everything into one build, first build will be made of one commit thats true, but if there is a queue then then jenkins will strip the queue into one multiple commit build.
You can limit the concurrent builds using the following block in your Jenkinsfile. Node { // This limits build concurrency to 1 per branch properties ( [disable. Concurrent. Builds ()]) //do stuff }.
This begs the inquiry “How to limit concurrent builds or stages?”
Limiting concurrent builds or stages are possible with the Lockable Resources Plugin ( Git. Hub ). I always use this mechanism to ensure that no publishing/release step is executed at the same time, while normal stages can be build concurrently. Show activity on this post.

This begs the query “How do I use the throttle concurrent builds plugin with pipeline?”
The ” Throttle Concurrent Builds Plugin ” now supports pipeline since throttle-concurrents-2.0. So now you can do something like this: Fire the pipeline below twice, one immediately after the other and you will see. You can do this manually by double-clicking “Build Now” or by invoking it from a parallel step in another job.
What can jenkins do?
Jenkins is used to build and test your product continuously, so developers can continuously integrate changes into the build. Jenkins is the most popular open source CI/CD tool on the market today and is used in support of Dev. Ops, alongside other cloud native tools.
Jenkins is a tool that is used for automation, and it is an open-source server that allows all the developers to build, test and deploy software. It works or runs on java as it is written in java.
This CI server runs in servlet containers such as Apache Tomcat. Jenkins facilitates continuous integration and continuous delivery in software projects by automating parts related to build, test, and deployment. This makes it easy for developers to continuously work on the betterment of the product by integrating changes to the project.
How can we secure jenkins?
We can secure Jenkins and configure global security through the following: Deploy Jenkins. War file to the server and start it. From the homepage (through URL), click on Manage Jenkins. On this page, click on the ‘Setup Security’ button. Check the ‘Enable Security’ checkbox. It is a good practice to have your own database for security. Select this option in the ‘Security More.
Now click on the Manage Jenkins & select Configure Global Security. Under the security realm section, uncheck the option Allow users to sign up. This will ensure that no new users can be created with your permission.
How do I enable security in Jenkins?
Open the Jenkins home page and click on Manage Jenkins. In the Manage Jenkins page, click on Setup Security button. In the next page, select the enable security check box. Here, the very first thing to be done is to set the security realm.
Access control, which ensures users are authenticated when accessing Jenkins and their activities are authorized. Protecting Jenkins against external threats You should lock down the access to Jenkins UI so that users are authenticated and appropriate set of permissions are given to them.
As an example, let’s assume that we want Jenkins to maintain it’s own database of users, so in the Security Realm, choose the option of ‘Jenkins’ own user database’ . By default you would want a central administrator to define users in the system, hence ensure the ‘Allow users to sign up’ option is unselected.
Should I set a longer quiet period for Jenkins?
If your coding style is such that you commit one logical change in a few cvs/svn operations, then setting a longer quiet period would prevent Jenkins from building it prematurely and reporting a failure. , and throttling builds. If your Jenkins installation is too busy with too many builds, setting a longer quiet period can reduce the number of builds.
Why is Jenkins in high demand?
Plugins: Jenkins is interconnected with well over 1,000 plugins that allow it to integrate with most of the development, testing and deployment tools. It is evident from the above points that Jenkins has a very high demand globally. Before we dive into Jenkins it is important to know what is Continuous Integration and why it was introduced.
The following are some facts about Jenkins that makes it better than other Continuous Integration tools: Adoption : Jenkins is widespread, with more than 147,000 active installations and over 1 million users around the world.
