1. Background 1.1 Problems with the Current Use of Jenkins The orchestration engine is unstable Jenkins is an orchestration engine written in Java, and it stops the world (STW) during a full GC. Under large-scale builds, STW can prevent Jenkins from handling new requests. Heavy builds stall Jenkins stores data in disk files; every pipeline and every build occupies a file directory, producing a huge number of files.

1. The Advantages of Multi-Cluster Tekton Builds Thanks to Kubernetes, Tekton already has good elasticity and can support large-scale builds. At the same time, developing Tasks mainly uses Yaml and Shell, which widens the range of scenarios Tekton can adapt to. The figure above is a sketch of Tekton across multiple clusters.

1. Basic Concepts master master is where Jenkins is installed and runs; it is responsible for parsing job scripts, handling tasks, and scheduling compute resources. agent agent is responsible for handling tasks dispatched from master; the actual operations are executed through an executor. executor An executor is the compute resource
