Build Discarder

Introduction

A global build discarder that's possible to override by adding a job specific discarder. The goal is to be able to have a global sensible default, that's possible to override if needed.

Getting started

The Default Build Discarder can be added here:
Manage Jenkins >> Configure System >> Global Build Discarders

Configuration as Code

Add defaultBuildDiscarder to your configuredBuildDiscarders with the standard logRotator settings.

unclassified:
  buildDiscarders:
    configuredBuildDiscarders:
    - "jobBuildDiscarder"
    - defaultBuildDiscarder:
        discarder:
          logRotator:
            artifactDaysToKeepStr: "50"
            artifactNumToKeepStr: "5"
            daysToKeepStr: "100"
            numToKeepStr: "10"

Override the settings with a job specific discarder

Adding a job specific discarder will make sure the Default Build Discarder is not applicable.

# Jenkinsfile
pipeline {
  options {
    buildDiscarder(logRotator(numToKeepStr: '30', artifactNumToKeepStr: '30'))
  }
  ...
}

Background

The build in Specific Build Discarder discards build independent of specific job discarders.
