Building on the previous two documents, Creating Jenkins Slaves Dynamically on Kubernetes and Adding Windows Nodes to Kubernetes to Provide Dynamic Jenkins Build Agents, this document mainly attempts to dynamically provide Windows build agents on Kubernetes.
1. Adding Pipelines
For the Kubernetes and Jenkins integration part, refer to the two documents above; here we simply create two pipelines to test with.
- windows - the built-in Jenkins pipeline example
