Throttling of builds

Some jobs are using many resources of the host node or running some jobs on the same node might cause the build(s) to fail. We can configure and limit job execution using Throttle Concurrent Builds Plugin.

Throttling OS builds

We configured a Throttle Category called “heavy_job” (Manage Jenkins → Configure System → Throttle Concurrent Builds). This category limits execution of jobs to one execution per node:

To throttle your pipeline job using this category, you have to adjust the pipeline script. Use ‘throttle’ step before the node definition with single-element-array argument with the name of the category as parameter of the ‘throttle’:

throttle(['heavy_job']) {
node('android-os-build') {
    stage('...') {
        // ...
    }

    // ...
}
}

All executions of jobs that will use this category will be limited according to the configuration in Jenkins system configuration as seen above on the picture - only one running execution per node.
